The SFMTA made a change in parking policy that actually works to support the City's often-mentioned but just as often-forgotten Transit First policy. While it doesn't generate nearly enough funding Muni needs to get into a state of good repair and deliver reliable service, it benefits everyone by increasing parking space turnover, decreasing greenhouse emissions, decreasing street congestion and double parking. It doesn't make sense to rollback something that actually works.
