A bit OT: bicycle corridors are one thing in SF that is mostly good with a bit of second order bad. Good – if you know the routes you generally try to ride with other cyclists, safety in numbers. Plus the wide green lanes help make it abundantly clear to cars that this is a bike lane. Bad – the other streets turn into crazy biking gambles. Every once and while I see someone riding on Guerrero and want to yell at them to go one street over (Valencia) and reduce your collision chances. It emboldens bicyclists to not follow the law quite as well, or maybe since the sample size is high, I don't know.
