We can hear the rumbling rage of the city's cyclists as we type this: As noted on Uptown Almanac, local cyclist Amy Farah Weiss captured some incriminating footage for SFPD bicycle cops totally not coming to a complete stop at a stop-sign intersection on Haight. She reports on this quite angrily because she was one of those cyclists dinged by a cop in last fall's crackdown on cyclists who did "Idaho rolls" at stop signs, yielding to traffic but not fully stopping.
As she writes, "I received a $388 ticket for failing to come to a full and complete stop at an EMPTY intersection on the Wiggle (In my case I applied my brakes and wasn't pedaling, but the officer wasn't moved by my "spirit of the law" defense)."
She then questions them directly about it at 1:10 on the video, at which point they are stopped at a red-light intersection. They basically refuse to respond to her questioning.
As demonstrated by this story, some cops don't really give too much of a crap about whiny cyclists, and obviously the ones stuck on bikes busting camping stoners for aggressive panhandling or selling weed in the Haight are the last ones to care about practicing what they preach with regard to stop signs.
