SFMTA should remove parking and replace it with passenger loading zones. That way, they wouldn't be blocking traffic, including public transportation. It's well known that free and subsidized parking encourages driving. Currently, passenger loading zones must be requested and paid for by businesses that want it, to the tune of thousands of dollars a year. [1] They don't, so rideshare and taxi drivers just block traffic lanes. There is no mechanism for passenger loading zones to be requested by citizens or designated by the city for public benefit.
