That's a fatuous response. There are many reasons why San Francisco doesn't have New York City levels of public transit, the most important of which is that it's a comparatively tiny city, approximately 1/8th the size of New York, by population. If the "bay area" were a single city with a single government, it would be much easier to build a comprehensive transit system. Moreover, New York has been one of the world's largest cities for over a century. It's had a while to get good at things. San Francisco was a cow-town until the 1980s. I realize it's self-satisfying to blame NIMBYs for everything, but the facts are more complicated.
