I spoke to an SFPD officer on Market and 2nd the other day, and he watched as five different cyclists ran a red light stopping vehicular traffic on Market. I asked him why he wasn't giving tickets to the cyclists, and he told me that he is specifically not allowed to. He reiterated to me that the official policy of the SFPD is not to enforce traffic violations by cyclists on Market Street. He told me that this is because the SF Bike Coalition has run a campaign vilifying police officers and accusing them of harassing cyclists. This is all at the cost of pedestrian safety.
I'm not making this shit up, either. I've been hit by two bicyclists in the last year who were running red lights while I was legally crossing Market street on foot. And let's not forget all the cyclists riding on the sidewalk or against traffic.
SF is a zoo enough without people gleefully ignoring all traffic safety laws to suit their own convenience, and I don't think we should make it any easier on the people who do it.
