I would add that SF is even more different in that nobody owns cars and the transit network isn’t rxtensive enough for one to rely on it for all parts of the city. So people end up taking uber and lyft everywhere.
70% of SF households own a car, so still a majority by a long shot [1].

40% drive alone, while a bare majority 51% use a car, bus or van for transport (including carpools).
It's so popular, nobody does it anymore.
People also cycle a lot. Most Caltrain services almost always have two bike cars.
