2. San Francisco
Walk Score: 80

Maybe Google employees prefer taking their glorified school buses off to campus, but the rest of the Bay Area makes due with a transit system that works out just fine for workers whose "do no evil" companies didn't opt for sprawling office parks.

This town was built on a small layout and has never been keen on letting the car expand its footprint. The city's compact, concise layout didn't take the car into consideration when it was incorporated in 1850 or rebuilt after the 1906 earthquake. Even while the rest of America was having a love affair with the car during the 1950s, local protesters were busy stopping freeways from running through town.

As a result, 17 of its neighborhoods rank among the top 150 most walkable in the country, with Chinatown and the Financial District sitting behind only New York's TriBeCa, SoHo and Little Italy. Only 1% of the city lives in areas dependent on cars.

This has made the city's mass transit especially vital. The Bay Area Rapid Transit subway system carries more than 100 million passengers each year and the San Francisco Municipal Railway takes on another 210 million. That doesn't include other commuter rail and bus service that adds more than 20 million riders to the mix.
