i dont know about it. im an EMT, and ive seen what seatbelts can do to people. i mean, yes they can save a life, but ive seen wrecks where someone has died or been pinned in a car for hours, just to die because they cant get them free just because of the seatbelt. i wear mine alot, but when i dont, i am making the concious decison not to wear mine because of what i see every day. in slower speed wrecks (under 40mph) seatbelts do a great job, but above that speed is where the people start getting hurt or killed by the damn thing yanking them back into the seat.
when its your time to go, its your time to go, and a seatbelt cant save you if your number is up.
