Many bus drivers are careful, safe and courteous, but a minority of them are outright dangerous. Some of the closest brushes I've ever had with vehicles has been school buses that passed me with inches to spare. City bus drivers seem to be better, but not always. I got behind a real doozy this morning. First, he/she straddled two lanes for several blocks, preventing anyone from passing. It was very slow to start at all of the traffic signals, and then stopped in the middle of an intersection to make a right turn without signaling. A truck in the intersecting street apparently was blocking the lane, making it hard for the bus to turn, so the bus driver just stopped in the middle of the intersection until the truck finally backed up. The bus caused about 20 cars (and me) to miss the green light.
