Minneapolis-St. Paul, which is as sprawl-y as it gets has done a pretty good job of connecting most of the area with paved bike-only paths. I am not sure how bad the situation in Bay Area is, but it is not easy to get too many people to bike to work 20 miles each way, every day. So I don't know how this helps unless most people live within a 10 mile radius of the work place.
