I thought cyclists were supposed to act like they are driving a vehicle when on their bike. Why then do I constantly see people driving their bikes through pedestrian crosswalks? These are for pedestrians, if you need to cross, WALK your bike. Am I wrong about this rule because it happens so often I am starting to wonder. It is also dangerous. And another thing, if bikes are supposed to act like cars, why are people driving their bikes like maniacs? Two weeks ago a cyclist clipped my side mirror when I was stopped at a light just to pull ahead of me. I just don't understand. I support cycling but where are the cyclists who follow the rules of the road? We need more of them around this city. —Cranky Commuter
