When I used to live in Mountain View, I rode Middlefield (the 2nd on the list) regularly. I don't think it is too deadly. Although I would ride from Ellis St. to Charleston, and not ride west of there. Maybe that's where everything happens.

Oh, even though I had my bike vs. car accident on Middlefield, is still think it is not dangerous. It was just a fluke. It has plenty of shoulder room, and nice big bike lane.
