Ca 1956, a high school classmate of mine’s father, a physician, had his sternum crushed which in turn ruptured the ascending aorta which killed him.
I once bought a '66 MGB as a hobby car. My mom expressed her concern that I'd be thrown from the vehicle if I were to get in and accident. I told her the chances of getting thrown out of the vehicle were minimal since I'd likely be impaled by the steering column.
