You have to have a license to cut hair or drive a car, yes, but I don't get good haircuts from every licensed cutter, and there are plenty of morons behind the wheel of cars. The guy that rear ended me a month ago had a license and everything, but that didn't prevent him from riding my ass in cold and wet conditions.

Everyone seems to think that more regulation will somehow change bad experiences they have. Not in any way, shape or form true. The wrench I learned from worked on jets in the air force, serving in Desert Storm. Then he ends up being a bike mechanic. The best wheelbuilder I know ain't certified to do more than drive a car, but he can pull a motor out of his car and rebuild it in a weekend, as well as tie and solder a wheelset that you'll never, ever have to true. OTOH, I've met bad mechanics that went to Park school or a similar program.
