Cycling laws are the biggest problem in LA. Depending on where you are in LA, you're either can ride on the sidewalk or you can't. There's no consistency. I'm not in favor of ANYONE riding on the sidewalk, but cops in LA in areas where you can ride on the sidewalk like to be dicks and give cyclists bogus tickets for riding in the street.
