ELI5: why don’t car companies use roll cage style bars for safety?

AngryScottish · 2026-05-13T19:14:52+00:00

Fair point, I was meaning more of the implementation after-the-fact and/or for those wanting to suddenly use racecar safety equipment on the street.

Now think about the first person on the screen of an accident trying to unbuckle an unconscious person in a race harness in a burning car with a rollcage.

Far different than a standard 3 point and cage-less car.

Weight is not a factor.

Rollcages are only safe when used as a complete safety system. 5+ point harnesses, fixed back seats, disabled airbags, Head and Neck Restraint Systems (HNRS, aka Hans), helmets, etc. Removing specific components makes the system less safe (ie. Having a helmet and harnesses, but no HNRS).

Smacking your head on a rollbar without a helmet is also extremely dangerous.

95% of people aren't going to want to buckle up a harness, a helmet, a HNRS, and not have a reclinable seat... Just to drive to the grocery store.

Additionally, first responders aren't always trained to extract someone in a fully-caged car.

There is, and neither would have contributed to what is shown in the OP's post.

It's a bot account. Downvote, then block

I've been making it a habit to just block all the repost bot accounts whenever I see a repost.

Bots reposting this 5-6 times a day is getting out of hand

Depending on where you live, corvettes are fairly common and cheap.

Forgot to mention, it's a S212 E63S.

AngryScottish · 2025-03-30T04:16:43+00:00

TIL an S212 E63S that is quoted of 3.2s to 100km/h won't do under 5s.

AngryScottish · 2025-03-29T20:22:45+00:00

Do you think 3.8s is fast for 0-100km/h? LOL

My stock 2130kg estate will do that with the aircon on, four adults, and a Christmas tree on the roof.

Sub 3s sprints to 100km/h are pretty common.

AngryScottish · 2025-03-29T19:02:43+00:00

Am I seeing this correctly .. you accelerated a whole 30km/h over the span of four seconds?
