I have no love of CM, but no hatred of it either. I've noticed it is a lightning rod for cager complaints, and that only 1 in 100 of the complainers has actually encountered a CM ride.
Thing is, a lot of CM rides take place without incident. They're just rides. They have less intrusion and footprint than a Funeral procession (who also run red lights), and far less then the innumerable parades cities sometimes seem to have. The selfish box-blocking drivers during rush hour cause more backups than a dozen CMs
The trouble comes when the police or they mayor says "Something must be done!" and starts cracking down for no reason. Willie Brown made a mess of things, and now NYC seems to do the same thing. Someone mentioned it being a Guiliani thing, but that's just not true, as the crackdowns are recent and Guiliani is no longer mayor.
Not everything G. did was gold, either. His pedestrian controls by blocking off sidewalks from the streets did nothing but uglify city streets for the benefit of motorists (who gained nothing).
