Did Google really transform Mountain View in the way that it proposes for San Jose, though? The Google campus in Mountain View still looks like a dressed up suburban business park to me, far away from public mass transit, just as it has always been. It relies on a private bus system to get many employees to work, which most other major Google offices don't need due to the effective mass transit (NYC, London, Zurich, etc.)
What is proposed for the San Jose campus seems far more urban, sited adjacent to a real mass transit station, like basically all the other major Google offices in the world outside of Mountain View.
EDIT: BTW, I'm not disparaging the Mountain View campus and private bus system. I've used both plenty, and they are a locally optimum solution for Google, given the lack of mass transit access, and the reality there is not enough parking for Google's high office population density. But a lot of what's there seems like duct tape and chewing gum workarounds on top of the mid-century suburban, car-centric model for siting work, housing, and transportation.
