I used to be anti seatbelt until a good friend and past employee went through the windshield of his truck. The truck wasn't hurt that bad and the passenger (who was wearing his seatbelt) is still alive today as are all the people in the other car.
That was the day I started wearing seatbelts like the law says. If you want to break the law then just be ready to pay the fine.
I think they should be required on school buses too.
