Inside, most riders appeared to abide by the shuttle's etiquette rules. Cellphone conversations are allowed if they are work-related and sotto voce. But loud personal calls are definitely out. In fact, except for a couple snuggled together, no one sat on adjacent seats.

Snuggling couples on the Googleplex commuter bus? So notes this New York Times article on the free shuttles, concluding that the buses are pretty much the second coming of Google-Christ, in terms of employee benefits. The 32 buses embark on 132 daily trips to move 1,200 people a day over 4,400 total miles among 40 stops. With tolerance of public PDA (and we don't mean Blackberry action), it's only a matter of time before the first Google bus-child is conceived en route.
