> SF is even more different in that nobody owns cars

70% of SF households own a car, so still a majority by a long shot [1].

Many of those households have more than one person in them (2.3 by the 2010 census) so I'm not sure it's a majority.

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.

Interesting. At 1.10 cars per household, and 2.26 people per household, about 47% of SF residents own cars. (Though subtracting out the under-18 population means 55% of driving-age residents own a car.) Also, given there must be some people who own more than one, the actual percentage is probably lower. Still, that's a lower number than I imagined.

SF also has like 1/10 the population of NYC.

People also cycle a lot. Most Caltrain services almost always have two bike cars.
