San Francisco numbers are misleading. They likely counted both BART and Caltrain. Since Oakland is included, Amtrak trains (Capitol Corridor, ACE, San Joaquin) might also be included. All the systems I mentioned are heavy rail and carry hundreds of thousands of passengers daily.

Muni has an always packed light rail subway system as well. Unfortunately, unlike San Jose's VTA, that subway has no bike carrying capacity. This makes it difficult to ride the bike to a light rail station and then use it again to reach your final destination in downtown or elsewhere in the city.

Regional heavy rail systems like BART have enormous ridership.

San Francisco buses need dedicated lanes in residential areas. Based on my personal experience, the root cause of traffic slowdowns appears to be double-parked cars. Buses run quickly at night when they are not slowed down by cars.

But this is changing. Dedicated lanes are being put in place. http://sf.streetsblog.org/wp-content/uploads/2014/07/Picture...
