10 minutes after I attended a bike protest demanding #ProtectedBikeLanes on Arguello in #SF, I almost got ran over by a car turning left at an intersection where left turns are forbidden. It is #NotJustArguello where we need protected bike lanes. It is not just increased enforcement. It is not just changing how we cater all our infrastructure to drivers. We have to change the culture. We have to curb vehicles every way we can. It is a matter of life or death. #bikesf #bicycle #sanfrancisco
