Congratulations to @MattHaneySF and the city for this achievement. But if it takes decades to get one car-free street, you can imagine how long it will take to get free public transit.
Right now, one of the favorite troll attacks on free public transit is to say --
"the system needs to be improved before it can be free"
They disguise themselves as "planners" and "cycle advocates" and pretend that free public transit is just a matter of city planning. It is not. It is a struggle against the oil-auto-sprawl profiteers. A mass movement for free transit will unite us, and then we will have the power to make improvements.
