The laws of physics suggest clearly enough that one ought were a seatbelt in a car, or helmet on bike. There is no need for the state to make redundant laws stating the same thing.
The state is not concerned even the slightest little bit with your safty. They want more reasons to pull you over and write tickets, and snoop around your car.
It might actualy be impossable to operate a motor vehicle completely legally in this state. Keep voting for statists and you will get more of the same.
