I don't know about other cities, but I've found bicyclists in NYC to be among the, well, most avoidable people anywhere. On the Brooklyn Bridge, the unwritten rule is that bicycles are going to race as quickly as possible, and pedestrians and slower bicyclists had best get out of the way. The same holds on the DiMaggio bike path. What is it with the costumes? And, if you are a pedestrian attempting to cross the street on the green, look both ways, because if you don't you will be buzzed by a bicyclist. Needless to say, I ride with traffic, stop at lights when there's traffic, and stop for little old ladies. Mr. Nice Guy, I suppose. Drivers are no better. Arguments over doorings have nearly gotten violent on some occasions over the years.
