>It already is, but based on the availability and popularity of buses, it's not likely.

I guess it depends where. Here in London buses are everywhere.

It's an interesting take on who's responsibility it is to provide transport. My personal view (neither more not less valid than yours) is that it should be the job of the local authorities to provide transport (council or state). It will help companies of all sizes to grow rather than leaving the responsibility on a few big corporations, and it would give access to transport to every employee, not just googlers. That's only possible if the tax system is well thought and functioning, including taxing said big corporations.
