Vision Zero is failing across the whole State.

It is because the whole thing is fucking stupid, in SF in particular.
You have a fundamental problem in SF in that they want to eliminate Traffic Incidents by making driving in the City as inconvenient as possible. You have a lot of really vocal douchebags, particularly the most vile subhumans of the Bicycle Scum set, who really have the goal of not allowing Cars inside the City at all. What is worse, for the most part, the City seems to be very comfortable with a zero enforcement policy for bad behavior by pedestrians and Bicycles.
It is a complete failure of leadership and of Government policy. Individual vehicles simply aren't going anywhere. The need will not go away and will not be reduced as long as SF remains an employment hub surrounded by millions of People in suburban sprawl.
Responsible leadership would be investing in infrastructure that made driving a vehicle in the City easier, more convenient, and largely separate from the pedestrian traffic, but they just don't have an interest in that, so you get the clusterfuck we have instead.
