i dont know, i have zero problem with helmet laws. if folks want to be dumb and skirt around them then thats on them and their buddies can pick up their skull pieces.
So you would be ok with the state mandating you wear one while in a car? While riding a bicycle? While riding on a Med? What about mandating eye and sar protection while shooting or mowing the lawn?
Where does the state get the authority to mandate personal safety equipment?
Seatbelt laws at least can be argued keep the driver in the driver's seat so they can remain in or regain control.
