Not exactly, that’s focusing on the rigidity and performance of the car. To survive a crash, the car needs to absorb energy rather than transferring it to you. New cars are designed to crush. Not only the body of the car, but the frame too. They also have better seat belts and front and side airbags. You can’t really build this engineering into a classic car (realistic). The only thing you can do to a classic car is structurally make it more sound, but then that also requires you to have a good restraint system and a helmet. You getting plowed by another car and you are in a solid chassis, caged car...your gonna take a good blow to the body. For everyday driving, I feel the only positive “addition” to a old car would be quality seat belts. I think Morris Classic is about all we got. Lap belts won’t cut it.
