Just because it’s in top 10 within the country doesn’t mean it is great and that people don’t need to rely on cars most of the times. “Just live near BART” is a laughable proposition since half the BART stations outside of SF do not have enough housing around them and the ones that do, have high density luxury apartments that aren’t exactly affordable to people outside tech and other high paying careers. Then there’s the question of “do I also work near BART?”, “buy groceries near bus stations?” Or “go to the hospital only near public transit?”. Answer to all of those questions is “No and I still need a car”.
