San Francisco tried to quietly push a controversial $100-per-year "driveway tax" on homeowners — and it didn’t go over well.City officials were exploring the idea of charging property owners simply for having a driveway connected to the public sidewalk (aka a “curb cut”) to help fill a $322 million budget gap in the public transit system. Critics called it “nonsense,” while transit advocates argued it was a fair use of public space.The backlash was swift, and now the city is walking it back. So… was this a reasonable funding idea or just another attack on car owners?
