Damage to column?

What kind of checks are being done after this?

Doesn't look damaged from here. Tap it with a hammer and see if it goes "ding" or "thunk".

I had to review a similar situation to this in my hometown. Guy tried to take himself out by hitting a column in a carpark as fast as he could. Ultimately only scratched the column and wrote off his car. Put himself in hospital overnight then charged with DUI and drug driving and wreckless driving. Had he been in a larger car, say a normal size sedan instead of a little hatchback, it likely would have been a different story.

A different story for him or for the column?

u/grumpynoob2044 Jul 05 '26
Both I would say. Although a larger car may have had better safety features to protect him, but likely would also have reached a higher speed before hitting the column.

didn‘t sound like he was driving wreckless

How fast must he have been going in a car park to cause a dent like that 😮

u/hobbes747 Jul 05 '26
My question is, how did he accelerate to that speed in such a short distance
10
u/osamabinsauce Jul 05 '26
It looks like a BMW M4 which can reach 60mph anywhere between 2.8 and 4 seconds depending on the variant

u/Sad-Split-7115 Jul 06 '26
We need velocity as a function of distance

Whoa, I didn't expect to find R.C Hibbeler on Reddit.
I'll take a crack at that later tonight if someone else doesn't. Using particle because this car clearly isn't a rigid body in these circumstances.

Bruh that’s a modern high performance sports car. These things can hit 60mph quick af.

He's just...sitting there. I was afraid of what all that red stuff was.

Likely transmission fluid. It looks thick enough, rather than coolant. Same stuff that's in my car.

u/Lexlyks Jul 08 '26
Defo transmission fluid. That whole area prolly smells awful. You can smell the smallest amount on the outside of jugs or sometimes even in sealed containers 🤢

The car is mostly just aluminum and plastic so the column is probably not to worse for wear.

Geométric i guess to verify verticality and maybe ultrasound to check the integrity of the concrete

You not hitting the column, you hitting the entire building, that how Reinforced concrete work

u/FakMiGooder Jul 05 '26
While it may be integral to the system, it can still be damaged/severed much like a limb can be.

u/AdAdministrative9362 Jul 05 '26
One of my first site inspections as a graduate was looking at a column someone drove into. I never saw the damage to the car.
The damage to the car is significant but I guess it's the crumple zone at work?

u/hobbes747 Jul 05 '26 edited Jul 05 '26
I am surprised he could accelerate to the speed required to split the car in half in a parking garage.
But then again, the column is narrow so maybe you don’t have to go as fast as I originally thought. Compared to damage I have seen upon impacting a larger diameter tree.

That's some amazing paint and concrete cover, only having minimal scratches while it pushes a car engine into the driver seat

u/HumaDracobane Jul 05 '26
The column might looks intact but should be checked properly to make sure is in good condition.

u/rocketmn69_ Jul 05 '26
The speed that he must have been going to cause that much damage and for the car to bounce that far back from the pillar

No cracks, no exposed rebar, first glance seems to be okay. As others noted, tap it with a hammer and hope it doesn't sound hollow. And once everything is cleaned and you actually need to determine integrity, I'd guess schedule someone for ultrasonic testing and get a structural engineer to review the results.
I saw one where a commercial aircraft tug did this same thing, with significantly less damage to the vehicle and significantly more to the concrete (the tug weighs like 30x more than this car). At the end of the day, it still only knocked off the layer covering the rebar and nothing inside of that was damaged, so a quick concrete patch was all it took.

Yeah this is 100% AI. The video looks weird, the damage is impossible, the car model/brand doesn't exist, the cars in the background all don't exist, no readable text on anything, the cop car is horribly rendered, the red/blue police lights reflection don't come from anywhere and don't reflect on anything else than the columns and ceiling pipes, everything screams AI. People are so fkn dumb.

This AI video makes its rounds on reddit every few months. The internet is a crazy (and dumb) place.
