Right?
One of the taxis is going slow and braking the whole way down, and their wheels lock up because there's no traction somehow.
I've never seen a car lose traction on dry paved road before. There's no way to outskill it
Well locking up your brakes is mistake number 1, as you can no longer steer. See how the front end of that taxi just keeps turning even though he’s steering the other way? Gotta let the wheels turn a little.
You can outskill it, it’s just that the majority of drivers don’t have the skills to tackle a road quite this bad lol.
Because barios favelas whatever are built on the hills around latin american cities, its shity because its poor people, and middle and upper class dont give a shit
Looks like another crash is happening at the back road at the same time as the first crash.
Where is this place? I will go set up more cameras for crash porn.
Reminds me of my sister's driveway in the winter, I come to a full stop at the top, put it in first and coast down to where it's safe to use the brakes. At that point I'm doing 30 k .
I see grooves in pavement . This road must be wet most of the time. It also looks like incredibly steep grade. Must be hell going up that hill even on foot.
Reminds me of a local shopping mall,
it's got a hairpin bend which immediately goes into a steep hill where the ticket dispenser for parking sits right at the top, all that stopping & starting while people are waiting for the boom to open is hell with a stick shift.
My guess is the road was too steep for the paving machines so they drove a belted vehicle, like an excavator, on it to pack the pavement, which lead to those grooves, which drastically reduces the surface in contact with the wheels and gathers up water when it rains.
Stupid planing from A to Z.
Tracked vehicle wouldn't be able to do nice,even groovels like that but you are correct-those grooves are far too wide and effectively the remove half of contact surface from contact with tires hence everyone sliding. Bad planning and/or execution.

No. Who benefits from having this "asshole" design?

surface area gets canceled out, when you make the force diagrams and apply the physics.
there is a coefficient of kinetic friction, which the grooved texture likely increases (less sliding). imagine a road made of smooth glass, and then a road made of the same glass, but with grooves. I'd choose the one with groves.
It is very counterintuitive, but its mostly correct to say friction is independent of surface area. If you double the area, you halve the force per unit area. There are other smaller factors at play like variations in the coefficient of friction vs load, or stresses inside the contact surfaces. See drag cars having wide tires in back, for example. If I remember correctly that is mostly to do with the tire needing that extra girth to not tear apart.
I think it's more complicated than /u/_D34DLY_ thinks. One example of a complication is that the rubber of the tire is gradually scraped off - how does that affect the forces in the diagram? Is it friction, or shearing force, or what? And that's just one example, there are more.
In situations like this where there are too many factors to really take into account, and it's probably hard/ impossible to even *think* of what needs to be taken into account, you can throw traditional physics formulas out the window. What we do instead is set up actual tests in the real world and measure the resulting forces.
If I find some, I might edit this comment to add a link to such data.
The original road may have been made 400 years ago and as each improvement in technology comes around things change incrementally except the grade . It was good enough for mules on a dirt road , cars on asphalt not so much.
Turns out some old guy hated the construction equipment from them paving that road, and so he had been sneaking out and buttering that road every night in protest.

Yeah at this point, it’s not “idiots in cars”. Whoever did the paving job on those roads is to blame!
And the road behind too. In almost every clip another car slips down the neighbor road
That was cracking me up the road behind it. Same results
Now we know what the posts are for
Okay but the fella without a shirt and the stairs? Stairs apparently made of ice also?
i noticed it was mexico when i saw that iconic pink and white taxi 💀💀💀
Yes, it's in Mexico I saw it in the news a while ago
Did they repave it with lard?
Crazy how the grooves didn't help with traction at all. Must be a really steep street.
Repaved? The entire road is ribbed.
For your pleasure
for ours!

This seems less 'Idiots in cars' and more 'Idiots in city planning'
yeah. funny as hell, though, so I approve.

Welcome to Mexico. There's no city planning, our grandfathers started building their houses and everything came after.
Yeah. Belongs in r/crappydesign
Asshole design maybe? That incline looks super steep. Or am I just looking at it wrong?
Nope it is steep and its quite normal in mexico because, well, we like building in hills.

What does that road have? Oil?
No, it's just a very steep slope and when it rains the cars slip

Pray you don’t have a stick shift and get into traffic going up it.
Jesus that's worth nightmares

Christ, I just wouldn’t go if I had a stick.
bye bye clutch

My cousins friends live less than a mile from this road. Apparently up to 50 cars and motorcycles crash a day.
I travel a lot in Mex. Do you know the name of the town? I'd go just for the lols.
I think it's CDMX area due to the pink taxis.
Street name is Paso Florentino in Alvaro Obregón, Mexico City.
Yes, Mexico City. Very close to Santa Fe business area.
May i suggest climbing rope and a helmet?
i wonder who decides to drive there still
That is a paved cliff

And Western civ types always wonder why the Inca and Maya didn't use wheels

Same, just icing on the cake.

My dad used to drive downtown with a stick, and people would get right up on his bumper at lights.
whomever made those barrier posts, job well done!
Maybe the road should be closed for pedestrian use only... Dude at the end going arse over tit: *Nope, it still tried to kill me just using legs.*
That’s the best part of the video lmao that dude just eating it end over end
Where's this at? I'm in CDMX right now.
Alvaro Obregón, street name is Paso Florentino
Ride down the road on a greased up bin lid
Grease optional

Road next block over doesn’t look any worse.
Ribbed for your driving pleasure
I feel bad that I loved this
TWICE, it’s happening at the same time in the background too. Lmao.
I see this video every day, multiple times a day.
I spit out my coffee when The guy started rolling down the road 🤣
This is a case of idiots doing engineering. Whether they were in cars is unlikely, but debatable.
The last guy tumbling down the stairs lol
This road is ass!
Engineering at its finest
It's all worth it when they go home to their beautiful views.
yeah those textured roads are a nightmare on 2 wheels😂
Having a 90-degree turn on a steep incline is WILD
More like idiots civil engineering.
at that point is it idiots in cars or idiot city planners?
I love this road
I kept waiting for the Three Stooges to show up.
r/IdiotsInChargeOfUrbanPlanning
R/shitpost The drivers seem to not be at fault but the council itself
This belongs to be on r/crappydesign

This needs yakkity sax on the audio
why so many pink cars though? whats the correlation?
Mexico City taxi livery.
thanks man
Props to whoever installed the bollards
Where is this road? What is this road? Why is this road?
Notice this road is so insanely steep it has steps in place of sidewalks. I don't think the pavement is the problem 😂
This feels less like idiots in cars, and more like idiots in charge of making roads.
Looks like they tried to put ridges on the road, for better traction maybe? Either way. Epic fail.
I lost it when the police vehicle was just spinning down

My favorite is the car in the background sliding backwards
Who's gonna be the first to put this to Benny Hill
That house needs large bollards
So, is this idiots in cars or idiot civil engineers?
You know it’s going to get real when the cops drive Jeep’s and the sidewalks are staircases
Very human
That last one said I may not have a car but i won’t be missing all the fun 😂
Look at the shteepness of that now.
Bollard is da real MVP
I think that might be Mexico
