To the parent(s) who keeps defending ATV riding on the streets, can't teens ride street-legal mopeds that are registered and insured? How about mountain bikes? Public streets are for the benefit of joggers, baby carriages, skateboarders, dog walkers, legally-regulated vehicles, etc., all of which are put in harms way by the illegal riding activity of unregistered and uninsured quads and dirt bikes. The public, public safety and traffic laws are about everyone in America, not just a few who elect to break the law and endanger everyone for their own, self-serving interests.
