First, let me say I enjoy cycling, and do it responsibly. However, my experience in multiple locations around the urban Bay Area is that most cyclists only follow the rules of the road when it suits them and ignore the rules rest of the time. They consistently run stops signs & red lights, cut in front of cars, switch lanes and make left turns in traffic with no signal or warning. Then when one of them is contacted by a car or truck, (usually the cyclists fault), they "literally" start screaming about thier rights. (and no, I've never hit a cyclist). Also, if youv'e ever seen "critical mass" cyclists in San Francisco snarl traffic downtown at rush hour, week after week to make a point about sharing the road, (or in thier case, NOT sharing the road), you might be more inclined to consider many cyclists a hazard. I don't hate cyclists, enjoy cycling and respect "responsible" cyclists. But think "aggresive" urban cyclists hurt their cause far more than they help it. Not only that, even when they are "in the right", when accidents occur, the cyclist always loses to the motor vehicle. One more thing, if you are packing while you ride and don't have a CC permit, that's a Federal offense. Not responsible at all...
