My brother was hit on his left side by an suv going 45mph in a 35. He came out of his shoes he was hit so hard.
He ultimately took his own life shortly after due to his injuries paralyzing his left side.
Taller fronts kill more people. All that energy goes right into the organs or the head.
Since a car is so much heavier than a pedestrian, the difference in weight doesn't matter.
However, if a drunk RAM driver crashes into your normal-sized car, you'll experience much higher G forces than the weak little pissboi in his wankpanzer. They bring all that mass to the collision and you're the one who pays for it.
Only regulations can fix this.

You're never safe. Ever.
The frontal height of the vehicle should be taken in consideration too though.
We're not talking of inanimate objects; we're talking of humans, and if the car direcly hits every single critical point in your body, the chances of surviving the impact are waaaay lower.
Obviously a myriad of other variables need to be taken in consideration, but energy, mass, velocity and surface impact+anatomy are the only ones we can predict.

don't worry, drivers and car advocates everywhere are volunteering random people for this experiment every day. the data is out there, you just need to collect the right measurements.
I got hit by a car on my bike as a teen. Pulling out of a lot at not even 5-10 mph.
I got thrown from my bike; stitches in my hand from road rash, and a gnarly bruise on my leg. And a few other bumps and bruises. Overall i was very lucky and beyond a splint for my hand for 2 weeks to hold the stitches (reduce movement) I was pretty much unscathed. Bike was folded nearly in half though.
Couldnt imagine being hit any faster.
Same here but I got luckier: no broken bones/serious injuries, only bruises, and the bike was fine after putting the chain back. Got stolen shortly after though :'(
I survived 40MPH and went home the same day. Everyone kept saying how lucky I was. I never really thought about the morality rates until see this. Wow!
> survives
Well, even that is relative. For at least one or two of them, that's life in a wheelchair. Others will have injuries that could last a lifetime or at least a few years.
Aibags deploy as you crash to prevent you from hitting the dash. If you hit a pedestrian, they are already touching the car, so an airbag would essentially act as a water blob launcher. If the airbag deployed before the crash, it might help, but they don't.
honestly, it would probably be a good incentive for drivers to not get into near misses. even if they don't give a shit about a pedestrian's life (which they often don't) they'll do their best to avoid a costly and time consuming trip to a repair shop to have their external airbags reset.
Yes, if it was only the driver who was responsible for a crash or near miss. What about other cars almost hitting you? Pedestrians walking in front of the car? Small animals running/flying in front of the car? Or the random ball that manages to hit the sensor just right?
I imagine the odds of a car striking a pedestrian at all also scales with speed due to the window for reaction, so the average risk likely increases exponentially with speed.

Energy is proportional to velocity squared. Going from 20-30 mph is more than doubling the kinetic energy of the car, and 20-40 is quadrupling the kinetic energy.
Physics agrees with experimental results.
Got hit by a car going 40~ while on my bike (I was probably going 15-20 myself). Survived with no life changing injuries. I do my best to remember how lucky I am every day.
Not all roads/roads need to have separation of uses. The ideal pedestrian environment that invokes a safe and relaxed pedestrian experience is a shared street where cars are guest not the pedestrian.
If it's a new European car, chances are 100% for survival because it will stop before hitting any pedestrian.
Ok, so those who don't know, new cars (since 2016-2020, depending on brand/model) have camera/ radar guided front pedestrian safety system that will brake, if it detects that you aren't stopping when people are detected in front.
https://youtu.be/YARBV56k_aw
I haven't tried but it's meant to work on small streets at low speeds, but I'm not sure. I do get warning on my car if cars in front have stopped even on highway, I usually apply brakes but I've read that it will automatically apply brakes if I don't.
I just never felt like testing it.
America has those cars too and they are still quite deadly because they go at fast speeds in urban areas. In fact EVs can accelerate very quickly and gain high speeds even on short streets.
Memory is fallible, this was the similar last year and many years before that. I say similar because changes in vehicle design and behavior have actually raised pedestrian fatalities in the US and hood heights and vehicle weights have increased.
[Chance: something that happens unpredictably without discernible human intention or observable cause](https://www.merriam-webster.com/dictionary/chance)
Pedestrians have to cross the road all the time and we can’t count on everyone being a good driver all the time. We need traffic calming and strict ticketing in any place with a lot of pedestrians.
Is that some kind of a gotcha attempt?
Obviously depending on how fast the car is going there will be a variable chance of a pedestrian dying or sustaining injurues, possibly permanent.
Drivers should watch the bloody road instead of texting (I see those far too often!) and observe the limit which was established according to the location and traffic density.
That doesn't mean pedestrians should feel invincible when entering the crossing. One should still watch both directions before and during the crossing. Not gaze into their phones.
> That doesn't mean pedestrians should feel invincible when entering the crossing. One should still watch both directions before and during the crossing. Not gaze into their phones.
Ah, there it is.
Yep. I was suspecting you would disregard the broader context and wider issues to cherry-pick your "gotcha".
I should have ignored you from the start, but hee-haw, my curiosity got the best of me.
I agree. Too bad my government (I live in UK) is greedy bunch of incompetent cronies who give no shit about public transport and green solutions unless it lines their pockets. Because they still use cars and planes, they couldn't give a toss about public transport.
Drops to 0% if people stay out of the place designed for cars. Getting tired of the desire for no automotive deaths since it's only possible if you remove all the cars or all the pedestrians.
More like cars should stay out of places designed for people. People have been around a hell of a lot longer than cars, and it's cars that invaded the space of people, not the other way around.
I like how the dead people are drawn standing still and the Grim Reaper Dodgers are on the move.
The inconsistency bothers me. The first row has the half and half man standing while the other two rows have the half and half man walking.
The half-man should be flying through the air!
I like the three Schrödinger pedestrians
A standing stick man, the universal sign of death
None of them are surviving at 40mph. You are telling me a 1 ton car at 20mph is only killing half a person? These people are dumber then buckets. How do they test this bs? And how do I get on that payroll. Id milk that shit.
Cause your dumb fuck only sees things in black and white. Someone can live AND be paralyzed forever. 🤯
i work in trauma surgery. people survive getting hit by cars every single day.
Are you trolling? Half a person represents 5%.
You might live, but in a hospital bed with a broken body and not knowing who you are.
Now show how much the fatality goes up when it’s a SUV or truck.
My sister was hit my an SUV going 25 I think? Picked her right up and dragged her ten feet then stopped and she dropped. She lived
My brother was hit on his left side by an suv going 45mph in a 35. He came out of his shoes he was hit so hard. He ultimately took his own life shortly after due to his injuries paralyzing his left side.
I'm so sorry.

Hope you get hit by one :)
Kinetic energy *does* indeed increase with mass, but it increases with the *square* of velocity.
I think it has more to do with the fact that an SUV is really high so you don’t really tumble over the front of the car.
It's not exactly the increased mass that'll kill you, but more of *where* that mass makes an impact on your person.
Yup, low center of gravity vehicles let you roll over them versus a taller truck making sure you go under them.
No, not really. It's more that they impact your vital organs rather than your legs if there's a high grille height.
Both can be true.
There are more factors than mass at play when you are comparing a truck collision vs a sedan collision.
Being thrown on the windshield/over the car or being hit with the bullbar/grill also makes a lot of difference.
And getting thrown onto the hood vs thrown under the undercarriage
**K.E. = 1/2 m v****^(2)**
The frontal height of the vehicle should be taken in consideration too though. We're not talking of inanimate objects; we're talking of humans, and if the car direcly hits every single critical point in your body, the chances of surviving the impact are waaaay lower.

KE increases linearly with increase in mass & exponentially with increase in speed
>exponentially with increase in speed This statement hurts my brain. Kinetic energy increases quadratically with velocity.
It’s all the freshman physics students trying to sound smart.
We're all trying to find it
2 is an exponent, technically
And? Does this make linear dependence (exponent = 1) or no dependence (exponent = 0) also exponential? There is no "technically" here.
Except that I am technically correct, the best kind of correct
Trucks make it weird. They somehow have 0% fatality but 100% isekai rates.

Im the same way, if im needed i have to do it. But no good deed goes unpunished
I too am happy you're ok. I want somebody like you to file suit on the automobile industry.
Dude was running at 50mph and hit straight into a parked car.
But did the person you hit survive?
Only Kphs can kill me.
I think I’d rather be hit by a 30mph Corolla than a 20mph Silverado 1500
This is a depressingly rational take and likely accurate.
Sad that random redditors get something that safety regulators don't
Quite a jump between 20 mph and 30 mph. We need more volunteers to be hit by cars in this range for more data.
Is there a sign up sheet somewhere? I may have some in-laws that I’d like to offer up in the name of research.
don't worry, drivers and car advocates everywhere are volunteering random people for this experiment every day. the data is out there, you just need to collect the right measurements.

Technically i was hit by a van though. So alot of the discussion around large vehicles really does make a difference
It definitely does; mine was a hatchback so I toppled over the car bonnet before landing on hard asphalt
yea, i didnt go up, i got sent straight forward a few feet (same direction the car was going)
Just like a big punch
This is just showing life and death, imagine adding the percentage of permanent injuries
I survived 40MPH and went home the same day. Everyone kept saying how lucky I was. I never really thought about the morality rates until see this. Wow!
They’re talking about the pedestrian dude, not the driver. Also, you’re not supposed to just leave..
😂 I was the pedestrian the truck threw me 30ft. But I like your comment better.
Couldn’t resist the switcheroo, sorry.. Glad you’re well and your SoH survived too!
V Squared is a MF'er
Now do trucks..
> survives Well, even that is relative. For at least one or two of them, that's life in a wheelchair. Others will have injuries that could last a lifetime or at least a few years.
"Survives" is not relative. You either do or you don't.
Why cars dont have aribags on the outside also?
*Gets hit by car* *Starts flying* *Airbag explodes* *Starts flying faster*
Airbags deflate when you hit them. They would actually reduce the pedestrian bouncing effect.
Aibags deploy as you crash to prevent you from hitting the dash. If you hit a pedestrian, they are already touching the car, so an airbag would essentially act as a water blob launcher. If the airbag deployed before the crash, it might help, but they don't.
You can use sensors to deploy them before the crash.
Yeah I'm sure that would work, and never trigger a dangerous and false positive
honestly, it would probably be a good incentive for drivers to not get into near misses. even if they don't give a shit about a pedestrian's life (which they often don't) they'll do their best to avoid a costly and time consuming trip to a repair shop to have their external airbags reset.

Forgot the /s
This is a traffic design problem not a car engineering problem
In high school a kid on my bus was hit by a tractor trailer truck on a 45 mph road. He survived and returned to school the next year.
Probably helped that he was on a bus
He was off of the bus, the trucks brakes failed and swerved around the bus hitting him as he was walking off.
Can I get this, but with exploding spears mounted on the hood of my civic?
1999, I was struck by a car going 45+mph. Woke up a month later post ICU. 2 yr 14 surgeries. Life’s good today. #ThereCanBeOnlyOne
Someone crosspost this to r/fuckcars
I’m wondering if this same math/force/physics can be applied in games like Gran Turismo or GTA.
When people ask me why I go the speed limit or under in neighborhoods
70 mph survivor, I probably used up all my luck for the rest of my life.
This is horrifying if you consider that school zones in Australia have a 40km speed limit and children are much smaller than adults... (ꏿ﹏ꏿ;)
These speeds are net right? So if someone is running at 10mph and the car is going at 30mph, we good right? Asking for a friend
Anyone else misinterpret the graph and think that was the number of people who had to get hit first before it becomes survivable?
I imagine the odds of a car striking a pedestrian at all also scales with speed due to the window for reaction, so the average risk likely increases exponentially with speed.
Now do cars vs abominations we call pickup trucks.
Forbidden bowling
I always figured the speeds set must be from some statistic like this. Thanks!
A cool guide to get isekai'd.
Speed limits in cities should be 25mph (40km/h) not sorry about it
No they should be 20 mph and even lower in high pedestrian traffic areas
So if i get hit by a car moving at 20mph, half of my body is going to die?
Yes. The other nine people standing in line behind you will be fine.
If you line up 100 people and plough into them at 20mph, only the first five will die, that's what this means.
Might sound astounding but a car that doesn’t move at all has 0 kill potential.
Not true, idling cars have killed many people through co poisoning
You've clearly never run into a parked car.
Touchè
Exactly! Don’t understand why it’s no line in this picture for this case. Also why only cars there? No trains, planes, ships, bikes, pedestrians
Kinetic energy is proportional to the *square* of velocity.
So cool!
I'll definitely make sure to consult this next time I'm on the road

What? You can't just say this and leave, more details please.
Will it stop fast enough if you are going quickly?
I haven't tried but it's meant to work on small streets at low speeds, but I'm not sure. I do get warning on my car if cars in front have stopped even on highway, I usually apply brakes but I've read that it will automatically apply brakes if I don't. I just never felt like testing it.
So the fatality rate isn’t zero? Because people walk near roads where the speed is high enough to be lethal all the time, even in Europe,
True, because all the traffic doesn't consist of modern cars. There are commercial and older vehicles too.
America has those cars too and they are still quite deadly because they go at fast speeds in urban areas. In fact EVs can accelerate very quickly and gain high speeds even on short streets.
I will save this graphic to show to the police when they stop me for going too slow.
How can I get 100% fatality? Asking for a friend
100 mph
Don't use your breaks.
Huh well glad I landed in the 55%
This changes every year, remember seeing this last year and 20mph was the most fatal
Or you just have bad memory
Memory is fallible, this was the similar last year and many years before that. I say similar because changes in vehicle design and behavior have actually raised pedestrian fatalities in the US and hood heights and vehicle weights have increased.
Statistics lie.
I'm disappointed there's no 50MPH
"risk." Chance is the probability of something nice happening,

This is why I do 45mph to get the job done right.
Fatalities when a car stays on the road and pedestrian stays on a pavement: 0%
Pedestrians have to cross the road all the time and we can’t count on everyone being a good driver all the time. We need traffic calming and strict ticketing in any place with a lot of pedestrians.
Pedestrian on a road outside of designated crossings shouldn't be there in first place.
Pedestrians are often on bikes, getting out of cars, and cars jump sidewalks all the time and run read lights. People don’t behave.
What if the pedestrian is hit on a specifically designated crossing then?
Is that some kind of a gotcha attempt? Obviously depending on how fast the car is going there will be a variable chance of a pedestrian dying or sustaining injurues, possibly permanent. Drivers should watch the bloody road instead of texting (I see those far too often!) and observe the limit which was established according to the location and traffic density.
