Number of car-sharing locations: 696
Top neighborhoods: Mission, South Of Market, South Beach This is a city that stopped an interstate highway from coming through during the car-loving 1950s. It doesn't need your carbon-belching deathmobiles ... or so it would have you believe. C'mon, now. Supposedly car-hating San Francisco is a car sharing hub thanks to local fixtures such as City CarShare, which developed the first wheelchair-accessible car-sharing vehicle back in 2008, and BMW's DriveNow. The folks in The Mission who love themselves a weekend in Napa and Sonoma get their weekend wheels while Silicon Valley bros can bum a Beemer to touch base with colleagues in San Jose or catch the 49ers in Santa Clara (once they finalize their move next year, anyway). Besides, do you realize where the Times got those car-sharing membership numbers from? The Transportation Sustainability Research Center, right across the bay in Berkeley. San Franciscans may loathe the idea of car ownership in their dense, hilly city, but they seem to like the concept of car borrowing just fine.
