I wear mine, Ill admit sometimes I forget, and ill put it on later, but 85% of the time its on whenever I start the car, and when I was in highschool 3 people were in a single vehicle roll over in a truck, it rolled into a river, the 2 guys that had seatbelts on, drowned. The girl, who was sitting in the middle, survived by not wearing one, but shes in a wheelchair to this day.
