Lets look at it from a logical prespective. Our cars were designed and build when there were WAAAY less cars on the road. Traffic was a lot less and the injury stats werent very high because of that.
But now your driving your old car in a modern envirnment,one where the other cars are vastly superior in the braking and handling departments. Not likely you'll be able to "drive" your way out of a predicament,and because your older car has what I'd call a "hard" interior your going to be VERY injured.
