Well hell, how long have we been registering cars for the public roads? There's always some gun fetishist posting in his underwear on this site screaming about how many traffic fatalities versus gun murders ---- even though no car is intentionally designed for it and those are all accidents....
Have it both ways much?
AMENDMENT 11 of the Bill of Rights:
A well regulated car, being necessary to the security of a productive State, the right of the people to keep and bear vehicles, shall not be infringed.
Great comparison! Registering cars is unconstitutional! Its in the bill of rights too!
