Thanks for posting that. And I agree, the guy on the video is being silly. Public transportation works in SF if you are traveling WITHIN SF. Trying to get to Google in Mountain View from SF, Berkley or Oakland via public transportation would be ridiculously difficult.
And within Silicon Valley, public transportation is very poor.
I once plotted out how to go 5 miles from home to work in San Jose. Driving took 10 minutes on all local roads, no traffic, piece of cake. If I wanted to use public transportation I had to walk, take a bus, walk to a different bus line, get connection, walk again take another bus, and walk last 1/2 mile to work. All told it would take 3 buses, 45 minutes to an hour, with 1.5 miles of the total 5 miles walking!
