SF #10 worst city in US for commuting

This was forwarded to me by a friend, so I don't have the original source. I'm happy to update that if anyone knows of it.

#10 San Francisco

San Francisco's biggest traffic problems are the result of bottlenecks. Due in large part to the city's geography, traffic gets nipped by bridges which force all traffic to a handful of pressure points, because they're the only ways to get in and out. Between mass transit, subways, street cars, trolleys, ferries, carpooling and walking, 28% of metro residents avoid single-driver commuting, the third best rate in the nation, but the delays of 60 hours a year (the second worst, behind Los Angeles) and the high rate of commuters spending an hour or more en route (10.5%) really slow things down.
