Back in the 1950s and 1960s if you got hit or you got in a really bad car wreck you were pretty well going to be dead or hurt and maimed for life because let me tell you they didn't have much in the way of safety equipment. A lot of them just got impaled on the steering wheels. You know what happened to people that went through the windshield before they had safety glass. A lot of people got thrown out of the car and then the car rolled over on them. A lot of them were trapped in the car and burned alive. And a lot of people just brushed their teeth on the dashboard which was usually made of solid metal and bashed their brains out too. Or just caved their faces in. Believe it or not I know a couple of guys that were working on their cars underneath the car without jack stands they just use the jack that came with the car.... That ended badly....
I had a friend who burned in a car accident and lived because he had his seatbelt on. The buckle became jammed and he could get it undone right away. Burned his ears off it was so hot. I didn't wear belts for a long time after that. These newer designed buckles are better.
