Good point, since it says "to work". But I can't imagine anyone could live in SF and drive three hours one way. I would assume it's round-trip, and that it's to the South Bay. Netflix is in Los Gatos, for example. (But then anyone who's had NFLX options for more than a couple years can probably afford to have two houses in the Bay Area....)

Anecdata: I know of multiple people that drove 3+ hours each way to work in the Bay. ~10% of the commuters I know there. It's not a majority, but it happens with frequency.
