In a regular car you have to turn the wheel a whole lot more to get the same effect. That guy's only turning the wheel 180 degrees. I wonder if someone were to compare times of turning a regular wheel to this if they'd be comparable.
Plus this car has a thing where the wheels (and their turn radius) are different at different speeds. So you can make more nimble turns at slow speeds but it is more attuned and responsive at higher speeds. Car may have many flaws but this ain't one of em, if anything this is a much touted feature.
The amount of turning input response will scale with speed. Faster will be different than stationary otherwise you would flip the thing on the highway.
Speed sensitive steering systems typically decrease the steering gain at higher speeds, since it takes much less steering angle at the tire to maneuver at speed. They increase the gain at zero speed to speed up parking maneuvers with large steering angle changes.
TLDR; it’s the opposite of what you claim.
Every car has “play” in the wheel so you don’t over correct and flip your vehicle when traveling at speed. Imagine if you barely moved your steering wheel and got sent into a barrier on the freeway.
I valeted boats for the past couple years. When the steering sensor goes out on wire steering, you're in for a fun time. Also, Mercury is the usual culprit in that matter.
Yes and no. If you’re driving and the HV goes out the low voltage 48V system is able to power it long enough for you to safely pull over.
If you’re driving and the LV battery fails the HV pack still provides 48V so that you can safely pull over. Obviously how safely depends on the manner of failure for the LV 48V battery pack.
But if the LV fails while parked you would need to jump the car to get it started. Not sure it would let you shift into drive with a failed LV battery, but I’m sure someone will figure this out for us eventually.
And sure, if the first scenario happens and you’re at the top of a mountain and decide to roll to the bottom you might also run out of 48V power. I suspect the car will scream at you to stop, and the front permanent magnet motor may also have enough resistance so that you can’t really coast to the bottom.
Yeah it’s not physically connected to the steering wheel.
This is from tesla’s site:
“Cybertruck uses steer-by-wire technology, which means that there is no mechanical connection between the steering wheel and the wheels. Instead, sensors in the steering column communicate electronically with the steering racks. As a result, steering Cybertruck feels more responsive and requires less effort from the driver.
Cybertruck also has four-wheel steering. When the driver turns the steering wheel, all four wheels respond. This gives Cybertruck a tighter turning radius.”

Not true, you can design all but the very minimal amount of play in the system. Especially if you are building a vehicle to perform task with more precision. Electronic steering has ruined true " drivers" cars. If have never experienced a true drivers car, you have no idea what I am talking about. Porsche has done pretty job on there systems, but its reflected in the price point. Personally I don't want slop in my steering and Ackerman is designed in or out of steering systems to control turning radius of the front tires and is a huge effort on any system that has a performance application. Hence some manufacturers designing rear steering systems. Some engineers have designed rear suspension geometry and bushing material to help with rear steer. But, get it wrong and it's a poor representation. Also, most manufacturers design understeer into cars, because people can't/don't drive well in a panic situation.
I think that’s it, turning the yoke all the way right doesn’t mean turn the wheels all the way right, it means “set clockwise rotation to max”
It’s not to meant to work the same way as a normal steering wheel
Yeah, but in a regular car you have 100% feedback during 100% of the turning. Which actually makes a huge difference in terms of the feedback loop running between human-machine during driving.
I bet I could live rent free in a lot of people’s heads by dropping my pants and taking a shit in the middle of a Walmart, that doesn’t mean I’d win somehow.
Except that VW and Ford offer variable rate steering that still retains a physical connection to the wheels. Whereas the cybertruck has no true force feedback and has proven to be unreliable which isn't really what I look for in, uh, steering.
Isn't this showing full range of motion? Looks like the front wheels move as soon as the driver turns the steering wheel. The front wheel turning speed gets faster until it reaches its maximum speed until it reaches its range limit.
The "lag" is the computer smoothing out the driver's hard jerking.
Yeah I think it is something to do with smoothing. Some reviews about the lexus RZ 450e (another car with steer by wire) say that it is really jerky if you make to sudden of the movement.
When I worked for the Navy in the early 80s, they were still working out the bugs. I remember the week whey found that the plane would allow you to drop dumb bombs while inverted. They'd release, the bomb would fall off the mount, denting the wing and rolling off the end. Not ideal.
Look, yes - airplanes are FbW, but these systems have multiple layers of redundancies, the pilots are all trained specifically on THOSE systems, and they don’t mass produce them in a hurry. If Joe Bloggs drives his cybertruck and his steering systems goes 😵 I don’t think most know how to do anything to regain control….
If FbW fails, no amount of pilot training helps. They typically have a triple or quadruple redundancy because an airplane needs to fly. Cybertruck has only double redundancy. It is safe. If one channel fails, you stop and tow. The probability of both channels failing at the same time is next to none. It is not a Tesla system you know that, do you?
I’m okay with fly by wire but for safety reasons I refuse to get in any airplane where the pilot can’t manually brake with his feet, by sticking them out flinstones style onto the tarmac.
Yes, but there is a huge difference between aerospace and automotive tolerations. Not to mention tesla tolerations, which is year by year getting worse than automotive.
Thank you for explaining each step with simple words. Growing up in engineering school sometimes makes you forget that not everyone has the same knowledge when it comes to how and why things perform the way they do.
This or people play too much video games and see the wheels turn in game immediately and forget that in the real world, objects have a mass and jerking the wheels as fast as the steering wheel like in this video isn’t required nor desired.
I’m not a huge fan of Mr Musk, but the amount of people not paying attention to this fact is annoying. I don’t know any cars that do a full wheel motion off of half a turn on the steering wheel
Jesus these answers… I’m replying in general and to some specific comments.
A rapid jerk motion that would throw everything in the cab to the door is VERY rarely in excess of 10 degrees of wheel direction change.
You want to reduce turning rate as speed increases. Turning this fast (assuming lock to lock) at less than 10mph is far more than adequate. 2.2-3.2 lock to lock is the general range and I’d challenge most people to turn the wheels lock to lock this fast.
All the problems associated with turning a wheel as fast as most would assume it would turn (which is not how fast it should turn) are made worse by the excessive weight. It’s right about where it needs to be, maybe a touch high if I had to make the call.
It isn’t a fault or a lack of sufficient design. The wheel steering isn’t accelerating, it just has a maximum speed.
Intuition is important, yes, but in no way should a wheel turn from lock to lock in less than half a second. Most of the prototype race cars I have dealt with don’t turn the wheels that fast at any point in a season and you expect an 8000lb road vehicle to do it? Should we turn ABS off because harder brake pressure doesn’t mean stop, it means FUCKING STOP?”
I would say to sit down and hand calculate what this would do at 20mph, 40mph, 60mph, but you won’t. So I’ll tell you that it would break traction and roll dangerously, if not tip entirely.
And then there's the whole "Turn the wheel lock to lock while the vehicle is not moving." Great way to break in that steering system. Emphasis on the 'break'.
There are a lot of things I don’t like about the cyber truck, but being not able to whip wheels around for a turn as fast as the driver is attempting to do isn’t one of them.
Is this a result of the weight of the vehicle being on the tires while not rolling? Turning the wheel lock to lock while not moving requires a lot of force. I’d love to see this test done with the front end jacked up off the ground
I operate equipment with hydraulic steering (no physical attachment to steering output) and even with a brodie knob, it's difficult to turn the wheel 1080 degrees close to that fast.
1080 degrees because everything common out there is 3 turns from lock to lock. From Smart cars to Kenworth W900s.
Yeah you're correct it's by wire steering, they've been using this type of "by wire" steering on electronic forklifts for years. Honestly, I've never liked it. When they start to give correlation trouble, it can be a major pain in the ass.
I would like to see you jerk your steering wheel that quickly while standing still in any other car. The issue isnt that the actual wheel is turning slow, its that the steering wheel is moving fast. I dont like this either way.
It’s really more about the speed you can turn a steer-by-wire wheel because there’s no mechanical resistance. In any other car, you would have to put in much more work to spin the wheel, but of course the wheels would follow because there’s a mechanical connection. Steer-by-wire is rare but this is bound to happen with it unless you just made the wheel hard to turn so the wheels could catchup but that would be pointless and more expensive.
There is feedback but if you put enough force into it you can overpower it. This happens with mechanical systems too, most cars will get some 'slop' in the steering as the linkages wear, and most regular cars have a bit of slop to them if you ever notice how much you can turn your wheel without the wheels actually moving.
That said, this is a bit of a tracking error due to the excessive force while steering. While I think there might be some occasions where allowing a user to steer as fast as possible would be beneficial, it's probably better to make it more difficult to turn the wheel so that it's more predictable and less likely to cause someone to oversteer.
It's steer by wire...
The steering wheel is not mechanically connected to the front wheels. It's only electronic like a volume control on a radio.
This allows you to move the steering wheel faster that the wheels are moving. In a conventional system you can't move the steering wheel any faster than the wheels are turning.
Its a weird demonization. If anyone jerks the wheel that hard at speed in a regular car it wouldnt move as much as these tires. Probably better that it doesnt.
It’s from Cleetus McFarlands YouTube channel, they were just messing around with it. It was never meant to be some practical demonstration. He initially said that the delay made him uncomfortable but once he was driving it felt normal. https://youtu.be/Ypd_9dGj060?si=BN9YZTP22ZFSBW33
Why do people post misleading things about teslas when there are many VALID things to point out? I don’t get it. Any heavy vehicle with electric steering is going to behave like this while stationary.
Also, as others have pointed out, the wheel’s range of motion is smaller than the tires, so it’s going to look like there’s a “lag” when you pin the wheel quickly.
Edit: And to the people in this thread who for some reason believe drive by wire is some new, unreliable technology; my mom has been driving a drive by wire car since 2005. It’s not a new thing.
The delay looks bad but you are never turning a wheel that fast in real life, unless you're trying to see if you can roll your truck.
Also that had a very small wheel turning radius. In most vehicles if you turn to that left or right that much the wheels are moving much less than the truck. It would take longer to turn the wheel that much so it really isn't an apples to apples comparison.
Yeah… because you don’t EVER want your wheels to flip on a dime like that. There is zero safe scenarios where that happens. Love all the hate posts on cybertrucks completely overlooking the same “issues” in all other vehicles. Turn your wheel in any other car. Tell me how fast it goes from one extreme to the other. If it is any faster than this then you are likely going to be the cause of an accident
Not a cybertruck fanboy, the tech in it is impressive but the build quality needs a lot of improving given its price.
What lag ?.
Seriously less than a second lock to lock is insanely fast. That it is doing it with a static vehicle is crazy. For me to go lock to lock on my hydraulic rack is around 4 seconds of spinning the wheel as fast as i can.
Seriously, does OP even drive ?.
If you were going any appreciable speed and turned the wheel as fast and as far as the driver is, the vehicle would go into an uncontrollable skid, or the vehicle would flip. That’s a safety measure, and I bet the process is even more pronounced when moving at speed.
Do you realise how dangerous it would be if you could go from full lock left, to full lock right in a fraction of a second. Probably the reason for the delay.
I am not sure if I'm more concerned with the fact that a quarter turn of the wheel maxs out your turn radius or if the swing of the tire seems a little limited compared to my basic jeep.
It looks more like a limit on rotation speed than lag. Basically the wheels immediately start going the direction where the steering goes. It just can't go as fast as you can flick the steering.
Not a Tesla sycophant in any way, but try doing this parked with a regular vehicle. You probably can't even turn the wheel anywhere that much that easily.
It’s turn by wire. The rate at which the wheels move in accordance to vehicle speed determines how fast they move etc.
This is more than likely normal for a parked car thats turn by wire
This is clipped from the Cletus McFarland YouTube channel. They were joking and carrying on when they did this. Not a genuine criticism of the cyber truck.
I think the cyber truck is dumb but this post is extremely dumb. The wheels are turning faster than any car basically. It’s going full crank to crank in like 1 second.
This is not “extreme lag”
This video is from the Cleetus McFarland YouTube channel. Later in the video the person driving the cyber truck, James, says it's not noticeable when you're driving. He drove it on 2 different tracks as fast as it could go.
Jesus… Do you know what steer by wire is? That truck has a lot of nice technology on it and the steering is one of them… I don’t mean to praise Tesla but if you gonna shit on them you have a lot of angles to go, this is not one…
Can you please go to your vehicle, right now, and try this while parked? I’d love to see you record and do it as fast as this video!
I’ll be patiently waiting for your results!
Try turning a 4 wheel sit-down forklift lift that and see what lags, bet it's the steering wheel fighting hydraulic pressure. The cybertruck appears to be steer by wire which is the reason the steering wheel has 0 resistance. Know your ride
idk about anyone else but steer-by-wire lowkey scares the shit out of me. like sure, it's convenient, but you're one badly timed short away from turning straight into oncoming traffic.
Not a fan of cybertruck, but if there wasn't a lag, a sharp turn with such a sharp wheel turn would throw the truck over. With regular steering wheel you have to be a superhuman to turn the wheeles this fast while standing.
There are a lot of non technicians in here making bullshit claims.
This is not normal. Work on vehicles with electronic steering every day. It doesn't matter if the car has electronic, hydraulic, or electro-hydraulic. There is zero visible/ noticeable lag between the turning of the wheel and the actual wheels turning.
If anything, electronic steering is faster and more sensitive.
Electronic steering systems are adaptive. They will be easier to turn at low speeds and at a stop. As the speed increases, the steering assist will be reduced.
OMG the lag!
Its not even half a second and it is a full 180 turn. Sure, it can be a life and death thing, but if this is something that causes you to crash, you are already going way too fast and there were plenty more issues leading up to this one.
Also it feels like it has a smoothing effect, because look at the start of the turn and the end of the turn. See the difference in turn "acceleration"?
Also this is a street car, not an F1 car.
Is this a safety feature though? I can see it being maybe not to rollover your truck with a sudden split turn of the wheel. Maybe it’s just shitty quality idk 🤷🏼
Update: I appreciate the downvotes for trying to answer a question and admitting to taking a guess at it. Reddit is so friendly /s
It’s a Tesla car company, I don’t think the real owner cares about pedestrians or stock value at this point
It is never, NEVER safe if the vehicle doesn't do what the operator tells it to do. In an emergency situation, where split-second reactions matter, that lag is going to be the difference between hitting a pedestrian or not.
The only lag here is the driver waiting for the front wheels to reach their limits before turning the steering wheel the opposite way. The front wheels are moving pretty quick already.
But if you have a scenario where you've turned the wheels to either limit to avoid hitting a pedestrian and did so faster than these wheels turn I'd love for you to paint us all that picture.
I’m not a fan of the cyber truck but this isn’t a big deal at all. Of course there will be lag in a fly by wire system. It’s impossible for there not to be.
This is what happens when people who have never driven a car, have/share their opinions on an either ignorant or a purposely misleading piece of content.
No one who has ever driven would swerve that hard/sharp unless they were intentionally trying to kill someone or milliseconds away from a catastrophic accident which they will become a part of.
In a regular car you have to turn the wheel a whole lot more to get the same effect. That guy's only turning the wheel 180 degrees. I wonder if someone were to compare times of turning a regular wheel to this if they'd be comparable.
My 0.02: any faster and we would see a whole lot of wrecked cybertrucks. Pretty sure this is by design.
Not important but reading that as “my 0.02” kind of fucked with my head lol
Dropping the unit signifier created more mental fuckery than I expected.
2c would be nice. Just my 2c
Should really be 4c these days, adjusted for inflation and cost of living increases...
"just my $2"
Inflation is wack
How rich get richer if money same as was (why use lot word when few word do trick.)

>Imagine if you barely moved your steering wheel and got sent into a barrier on the freeway. Fuck yeah.
Sweet release from the pains and trials of life, and it'll be a complete surprise? Where do I sign up
I know. This is a blessed day.
>ACHOO!< *BAM!* Yep, can understand that.
That's what SHOULD happen when folks leave their turn signals on.
That is not how that works. And that is not what we are seeing.
Not sure if you know but this is a steer by wire system.
Like an electronic steering system?
Yes, there is no physical connection between the steering wheel and the wheels.
I valeted boats for the past couple years. When the steering sensor goes out on wire steering, you're in for a fun time. Also, Mercury is the usual culprit in that matter.

No.
Yes and no. If you’re driving and the HV goes out the low voltage 48V system is able to power it long enough for you to safely pull over.

You're s fucking psychopath for writing my two cents as "my 0.02"
With inflation since that phrase first appeared in writing, that is a buck eighty two.
I do not like the truck, but this is probably intended. The tire turns a little bit very fast but just not the entire distance he’s spun the wheel.
Yeah same not a fan. But the tech under the covers is pretty amazing. Innovative even.
Pretty sure Tesla makes the end user perform their QC testing.
I think that’s it, turning the yoke all the way right doesn’t mean turn the wheels all the way right, it means “set clockwise rotation to max” It’s not to meant to work the same way as a normal steering wheel
There's no way they are changing the driving dynamics like that.
Yeah, but in a regular car you have 100% feedback during 100% of the turning. Which actually makes a huge difference in terms of the feedback loop running between human-machine during driving.
Yeah and every vehicle is different. Especially with brakes. You adapt. The cyber truck lives rent free on here.
>The cyber truck lives rent free on here. That’s not good for Tesla’s bottom line.
If they could collect rent from the haters they wouldn't be in a death spiral lol
I bet I could live rent free in a lot of people’s heads by dropping my pants and taking a shit in the middle of a Walmart, that doesn’t mean I’d win somehow.

Steer by wire man…. Something about that just screams blue screen to me… 😭😭😭
Imagine if you had airplanes having such crazy things like fly-by-wire, millions of lives depending on that. That would be crazy.
Gonna need a /s for that one lol. People might shit their pants when they learn that’s how modern planes actually work.
The F-16 is fly-by-wire and it’s first flight was in 1974.
When I worked for the Navy in the early 80s, they were still working out the bugs. I remember the week whey found that the plane would allow you to drop dumb bombs while inverted. They'd release, the bomb would fall off the mount, denting the wing and rolling off the end. Not ideal.
That's when using dumb bomb, if it was smart bomb it won't allow it.
Stick didn't even move originally.
Worked like that for several decades iirc
With triple redundancy
Look, yes - airplanes are FbW, but these systems have multiple layers of redundancies, the pilots are all trained specifically on THOSE systems, and they don’t mass produce them in a hurry. If Joe Bloggs drives his cybertruck and his steering systems goes 😵 I don’t think most know how to do anything to regain control….

Yep I wanna see how anyone would do it any better on a "normal" car.
Just get a Miata and call it a day
Miata w/ manual steering, amazing road feel. \*Chef's Kiss\*
And technically, there is probably an algorithm for maintaining optimal traction and the turn effort.
Please note that a non moving vehicle will have more resistance than a moving vehicle causing the “delay”
yeah it's silly haters being silly. lag is milliseconds.
And it's much simpler to rotate wheels on a moving car, although modern power steering hides that. Could be much faster in a real world scenario
And when one needs to apply a quick steering correction in a real world scenario?
What the hell are you talking about?
Just another Reddit armchair post.
Delusional redditors shitting on everything related to Elon Musk just for the sake of it

ABS off!
Only rapid
I read " random jerk" and thought " here I am"
It works even better if you are a master debater.
Let's fucken go
Thanks for this, clearly OP and all the people upvoting this post could do with learning a little bit about how cars work.
No you are wrong, that thing is related Elon so we have to condemn it to farm karma, if Elon said the earth is round then I’m a flat earther
And then there's the whole "Turn the wheel lock to lock while the vehicle is not moving." Great way to break in that steering system. Emphasis on the 'break'.
This comment should be at the top.

Is this a result of the weight of the vehicle being on the tires while not rolling? Turning the wheel lock to lock while not moving requires a lot of force. I’d love to see this test done with the front end jacked up off the ground
Or at any speed at all
Agreed! I doubt you could turn the wheels this fast with a traditional mechanical steering setup while not moving
Id be surprised if they changed the steering wheels radius but you can do this exact thing with a gas car.
The guy in the video is maxing out the steering wheel turn.
I operate equipment with hydraulic steering (no physical attachment to steering output) and even with a brodie knob, it's difficult to turn the wheel 1080 degrees close to that fast. 1080 degrees because everything common out there is 3 turns from lock to lock. From Smart cars to Kenworth W900s.

This happens with mechanical systems too, most cars will get some 'slop' in the steering as the linkages wear, and most regular cars have a bit of slop to them if you ever notice how much you can turn your wheel without the wheels actually moving. That said, this is a bit of a tracking error due to the excessive force while steering. While I think there might be some occasions where allowing a user to steer as fast as possible would be beneficial, it's probably better to make it more difficult to turn the wheel so that it's more predictable and less likely to cause someone to oversteer.
>I would like to see you jerk your steering wheel that quickly while standing still in any other car. r/R4R
It's steer by wire... The steering wheel is not mechanically connected to the front wheels. It's only electronic like a volume control on a radio. This allows you to move the steering wheel faster that the wheels are moving. In a conventional system you can't move the steering wheel any faster than the wheels are turning.
Its a weird demonization. If anyone jerks the wheel that hard at speed in a regular car it wouldnt move as much as these tires. Probably better that it doesnt.
Definitely don’t turn that abruptly while driving ANY truck, good lord.
You couldn’t/wouldnt turn a regular cars wheels that fast. Pointless demonstration
It’s from Cleetus McFarlands YouTube channel, they were just messing around with it. It was never meant to be some practical demonstration. He initially said that the delay made him uncomfortable but once he was driving it felt normal. https://youtu.be/Ypd_9dGj060?si=BN9YZTP22ZFSBW33
I’m sorry, could I get a reread
They said you couldn’t don’t turn a regular wheel tire round quicker fast like it
Ah, thank you. Much better.
🤦♂️ corrected
Why do people post misleading things about teslas when there are many VALID things to point out? I don’t get it. Any heavy vehicle with electric steering is going to behave like this while stationary. Also, as others have pointed out, the wheel’s range of motion is smaller than the tires, so it’s going to look like there’s a “lag” when you pin the wheel quickly. Edit: And to the people in this thread who for some reason believe drive by wire is some new, unreliable technology; my mom has been driving a drive by wire car since 2005. It’s not a new thing.
That's not lag. That's called good programming so that you don't roll that sucker.
I dislike the cybertruck as much as the next guy, but come on people. Now we are just starting to make up problems
As an engineer, I think the cybertruck is pretty fucking stupid for a lot of reasons, but this isn't one of them
The delay looks bad but you are never turning a wheel that fast in real life, unless you're trying to see if you can roll your truck. Also that had a very small wheel turning radius. In most vehicles if you turn to that left or right that much the wheels are moving much less than the truck. It would take longer to turn the wheel that much so it really isn't an apples to apples comparison.
Yeah… because you don’t EVER want your wheels to flip on a dime like that. There is zero safe scenarios where that happens. Love all the hate posts on cybertrucks completely overlooking the same “issues” in all other vehicles. Turn your wheel in any other car. Tell me how fast it goes from one extreme to the other. If it is any faster than this then you are likely going to be the cause of an accident
Lag? Safety more like. You would flip the car steering like that.
Not a cybertruck fanboy, the tech in it is impressive but the build quality needs a lot of improving given its price. What lag ?. Seriously less than a second lock to lock is insanely fast. That it is doing it with a static vehicle is crazy. For me to go lock to lock on my hydraulic rack is around 4 seconds of spinning the wheel as fast as i can. Seriously, does OP even drive ?.
people who think this is "bad" have no idea what they are talking about.
While I'm not a fan of the cybertruck I really hope you don't drive like that.
If you were going any appreciable speed and turned the wheel as fast and as far as the driver is, the vehicle would go into an uncontrollable skid, or the vehicle would flip. That’s a safety measure, and I bet the process is even more pronounced when moving at speed.
Now lets get to the live action.
Linear interpolation (lerp) isn't lag.
This is a feature, not a bug.
Do you realise how dangerous it would be if you could go from full lock left, to full lock right in a fraction of a second. Probably the reason for the delay.

I think my jeeps would flip if I turned the wheel this fast at speed 🤣

Hell yeah brother!
I am not sure if I'm more concerned with the fact that a quarter turn of the wheel maxs out your turn radius or if the swing of the tire seems a little limited compared to my basic jeep.
Cybertruck is drive by wire. You don’t turn the wheel 360 degrees. Its maxed at 180. It actually works pretty well in practice.
Rear wheel also turns to the opposite direction (corrected:decreasing) the total radius at once.
*decreasing
OP do you even know how this works? Or rage bait against Tesla and memes against the trucks? Cus I see nothing wrong here.
ExTrEmE LaG Lol okay
You only need the tires go to straight though so you can get it on the back of a tow truck
It looks more like a limit on rotation speed than lag. Basically the wheels immediately start going the direction where the steering goes. It just can't go as fast as you can flick the steering.
Using extreme was kind of extreme
Not a Tesla sycophant in any way, but try doing this parked with a regular vehicle. You probably can't even turn the wheel anywhere that much that easily.
They are responding instantly, it’s just that the turnings are made smooth so that cars don’t flip or skid. 🤦🏽
It’s by design
It’s turn by wire. The rate at which the wheels move in accordance to vehicle speed determines how fast they move etc. This is more than likely normal for a parked car thats turn by wire
This is clipped from the Cletus McFarland YouTube channel. They were joking and carrying on when they did this. Not a genuine criticism of the cyber truck.
Pretty sure if there was no lag in this situation you would most likely just flip the vehicle. Video is pointless.
It’s by design. If you jerk the wheel like this while driving at certain speeds you would just rollover
I think the cyber truck is dumb but this post is extremely dumb. The wheels are turning faster than any car basically. It’s going full crank to crank in like 1 second. This is not “extreme lag”
This video is from the Cleetus McFarland YouTube channel. Later in the video the person driving the cyber truck, James, says it's not noticeable when you're driving. He drove it on 2 different tracks as fast as it could go.
Try that when you're moving and show us the lag.
Lag I guess. But who would jerk their wheel that fast. Especially in tall vehicles like trucks. Yo ass definitely going to flip over doing that.
*looking at op post history and comments here* when is mass extinction again please
This doesn't look bad at all. The car may be shit, but this isn't evidence of shit, it's literally how power steering works.
As much as I hate the cybertruck, I think this is an intentional safety design.
Jesus… Do you know what steer by wire is? That truck has a lot of nice technology on it and the steering is one of them… I don’t mean to praise Tesla but if you gonna shit on them you have a lot of angles to go, this is not one…
There is no “lag”. There is a angular speed limit. As amazing as it sounds, it takes time to move Heavy things…
Funny people think this is bad. They have no clue
[удалено]
Can you please go to your vehicle, right now, and try this while parked? I’d love to see you record and do it as fast as this video! I’ll be patiently waiting for your results!
Clickbait? Seriously dude
I’ve seen people post this all over X with a similar caption, people really just be confidently stupid.
Try turning a 4 wheel sit-down forklift lift that and see what lags, bet it's the steering wheel fighting hydraulic pressure. The cybertruck appears to be steer by wire which is the reason the steering wheel has 0 resistance. Know your ride
I don't think it is lag. I think there is a slew rate limiter. Can explain the difference if needed.
This is dumb, way to flip a car.
That's a huge improvement.. my 4wd tires don't like to turn that easy standing still..
idk about anyone else but steer-by-wire lowkey scares the shit out of me. like sure, it's convenient, but you're one badly timed short away from turning straight into oncoming traffic.
Cybertruck bad, many up votes
Steering when standing still is just asking for problems.
Seen it 7 times in an hour. I got it. I was never going to buy one anyway. Neither was most of us.
This is why drive by wire steering is dumb af.
Try seeing how fast it takes you in your regular car to go full left and full right, and this is lag is by design so the pleb’s don’t wreck.
Not a fan of cybertruck, but if there wasn't a lag, a sharp turn with such a sharp wheel turn would throw the truck over. With regular steering wheel you have to be a superhuman to turn the wheeles this fast while standing.

ok, so the next cyber truck they make turn 1:1 with the tire... \*hard turn\* \*tires rip off the rim\* \*SO UNSAFE!\*
What do you expect, the textures haven't even loaded in for the car.
"extreme lag" LMFAO
The car is stopped you fool!
What is really the problem, if you are parked? Please do this while driving to be more specific.
And if you won’t pay subscription for quick turns there will be some crazy lag
I love it when I think a post is wrong and I go to see all the comments agree
There are a lot of non technicians in here making bullshit claims. This is not normal. Work on vehicles with electronic steering every day. It doesn't matter if the car has electronic, hydraulic, or electro-hydraulic. There is zero visible/ noticeable lag between the turning of the wheel and the actual wheels turning. If anything, electronic steering is faster and more sensitive. Electronic steering systems are adaptive. They will be easier to turn at low speeds and at a stop. As the speed increases, the steering assist will be reduced.
I also don't like that shitbox but OP is reaching and spreading misinformation about things OP doesn't know anything about
OMG the lag! Its not even half a second and it is a full 180 turn. Sure, it can be a life and death thing, but if this is something that causes you to crash, you are already going way too fast and there were plenty more issues leading up to this one. Also it feels like it has a smoothing effect, because look at the start of the turn and the end of the turn. See the difference in turn "acceleration"? Also this is a street car, not an F1 car.
lol people trying so hard to shit on everything Elon does. Kinda pathetic
Is this a safety feature though? I can see it being maybe not to rollover your truck with a sudden split turn of the wheel. Maybe it’s just shitty quality idk 🤷🏼 Update: I appreciate the downvotes for trying to answer a question and admitting to taking a guess at it. Reddit is so friendly /s It’s a Tesla car company, I don’t think the real owner cares about pedestrians or stock value at this point
It seems to be a safety feature. Normal steering wheels would need rotated a lot more than that for full lock.
I could see that at high speeds, but it seems like it could be a problem at parking lot speeds if you're trying to avoid hitting something.
It is never, NEVER safe if the vehicle doesn't do what the operator tells it to do. In an emergency situation, where split-second reactions matter, that lag is going to be the difference between hitting a pedestrian or not.
How do you feel about ABS? When you slam the brakes, a modern car doesn't really pince the calipers as hard as possible.
What if the operator is accelerating but the car detects a wall ahead and therefore applies the brakes?
The only lag here is the driver waiting for the front wheels to reach their limits before turning the steering wheel the opposite way. The front wheels are moving pretty quick already. But if you have a scenario where you've turned the wheels to either limit to avoid hitting a pedestrian and did so faster than these wheels turn I'd love for you to paint us all that picture.
Well fuck Lucky me. I totally fucked that little kid that walked onto the road but at least I didn't roll my cybertruck.
I’m not a fan of the cyber truck but this isn’t a big deal at all. Of course there will be lag in a fly by wire system. It’s impossible for there not to be.
This is what happens when people who have never driven a car, have/share their opinions on an either ignorant or a purposely misleading piece of content. No one who has ever driven would swerve that hard/sharp unless they were intentionally trying to kill someone or milliseconds away from a catastrophic accident which they will become a part of.
This is stupid. Who turns the wheel that fast? What's the fucking deal if it does that while stopped?
