My dad installed seat belts in our car in 1956. In those days you had to put them in yourself. It wasn't easy, you had to drill holes in the floor and bolt them in, crawl under the car to install the nuts.
I feel uncomfortable driving without a seat belt.
I've got a friend that has been ticketed 4 or more times for driving without a belt, but she's one of those people that drives with the seat as far forward as it can go and is right on top of the steering wheel. She complains that the belt hurts her neck. She's one of the world's worst drivers.
I'm 5'2 and I have to sit right up on the steering wheel to reach the pedals. The seat belt cuts into my neck all the time, I have to stick it under my arm. But I suspect the damn air bag will get me if I'm in a crash. My face is right there on it.
