I always wear my seatbelt now. Ive heard stories that people heard from another person and such but until i actually talked to one of my friends who was a victim i finally wore it all the time.
He told me that he was sitting in the back and he and his friends were hit by a drunk driver. He flew from the back, through the windshield, landed 20 feet from the crash, and was in a coma for 4 months. The way he described it.. omg.. i always had my seatbelt on from then on.
