So, you dont care about children on schoolbusses? None of them have seatbelts.
And motorcycles are explicitly allowed, and have no restraints or harnesses. Mopeds, same. Scooters, same. Bicycles, same.
Adults *should* have the right to do risky behaviors that increases the risk of bodily injury. But no matter the link you put forth, doesnt explain why fucking schoolbusses that transport years 6-18 dont have seatbelts.
