It says something about San Francisco's housing density and public transportation system that Google needs to create their transportation alternative. It's not that Google employees have "fragile sensibilities" and cannot mix with the rest of the general populace. Rather, it's that everything is spread out and it's difficult to get around using the public transportation system. There are no Google shuttles in NYC because it's more attractive to live closer to the workplace and sufficiently fast to take the existing transportation. The local residents need to accept that high tech workers are there to stay and start solving these problems.
