I knew a guy in high school who didnt wear seat belts. So one time he is in a bad accident, gets thrown out of the car through the windshield... and lands in some bushes and walks away pretty much unhurt.

But unlike the OP, most of us know a fluke example like that does not accurately represent the other 99.999% of the time when not wearing seat belts and flying through windows is a helluva lot worse than staying strapped in the car.
