Sure that could happen, but in that scenario depending on speed even a fully caged car isn't going to save you. I don't think its representative of the vast majority of rollover situations. There are plenty of other scenarios, such as a low speed rollover where two wheels dig into the grass and the car ends up on its roof with no crushing of the passenger cell whatsoever.

As an example, here is a more high speed rollover where the car rolled 4 times. 3 point belt, no cage. Driver walked away. The roof is impacted, but absolutely nothing like the picture you posted. If you look at the channel he does a full walkaround of the car afterwards. Modern cars are very structurally rigid and specifically tested in rollover situations. Older cars? Different story obviously.

Two sides to every coin. No guarantee as to which side you’ll land on.

Posting a picture of a car that probably fell off a cliff, then drawing a straight line to track safety isn't even the same coin.

ExMB, a post without ‘search’. You’re slipping.

I’ve seen two crashes at Mid-Ohio with roof failures. One guy got out and walked around his car. The other was air lifted to a hospital.
It’s sometimes just down to luck. Have it your way.

Obviously all a compromise. Watching impact crash test dummies in both factory 3-point belts and 6 point harness, i am impressed with the amount of body movement that occurs (even in 6point harness). I think it hard to comprehend the forces generated in crashes multiplied by speed and mass. these are only at 30mph. See links.

Given how much body movement occurs in factory 3-point belts I can understand why a roll bar padded or otherwise is not ideal on street in a crash as bodies move forward and up and back a lot and likely more in rollovers. Would have to be well designed and tested.

So in our dual purpose cars on the streets with a rollbar, but no helmet and 3-point belts where crashes of all kinds seem at least as likely as on track, presents another side to the coin.
