I’m not sure what you mean, or what point you are trying to make re auto safety.
In my opinion and observations, the 1950s especially, were the safest, and also into the 1960s. In the sixties though, uni-body starting, with so many muscle cars on the road with teenagers with little experience drag racing did have a lot of accidents.
I once traded a friend my 1955 Buick for a 36 foot old cabin boat. The Buick was like brand new, and he crashed it hard. I saw it, what a shame. I think he lost control and hit a bridge abutment straight on. Front end smashed in. He mentioned he would have been killed, and that car saved his life.
re your model Ts ?? Like a wagon with no horse? crunch zones?? You mean weak accordion like? Then the doors can’t open?? You can’t get out? Have to be cut out? Forget anything you learned from the media.
