Manhattan has the same problem, especially considering how narrow the streets are (due to "free" parking) and the lack of crosstown subway lines. It looks like the MTA has started a new program where some busses have police-car-like flashing lights and dedicated lanes. I haven't had the occasion to use the bus yet, but it doesn't look like it does anything. Taxi drivers make it their goal to use the road as rudely as possible, and there are a lot of taxis in Manhattan.
