Motorcyclist are the worst offenders, they don't seem to follow any laws/rules whatsoever, and they think they can do whatever they want as long as they can squeeze their motorcycle through. They use Zebra crossings as U-turns, blow redlights at every intersection, they turn right or left from lanes that are not designated as such, they drive against oncoming traffic, refuse to wear helmets, ride more than two-up, ride perpendicular to traffic, change lanes without signaling (or looking), ride and/or park on sidewalks, block traffic by parking in no parking areas, etc etc etc......they seem to believe that all laws of man and nature are null and void when they head out on one. To top it off, I believe it was stated in the news at some point, that more than 35% of motorcyclists don't even have a license.
