You're just being silly. The government shouldn't be doing things that private industry does already. In this case: there are fleets of buses running all over

You're just being silly. The government shouldn't be doing things that private industry does already. In this case: there are fleets of buses running all over the Bay Area, run by companies like Bauer (which provides the shuttles for Google). They are on time, clean and well-maintained (and the drivers don't give you any attitude).
