> You’d think if using commute time productively was a big draw, everybody would be riding the bus already, right? No, because the buses themselves are not a reasonable working environment. Every single person I know who can take the train to work does, many of them able to work (on trains that allow working - that's not, e.g. subways anywhere I've seen). Not a single one of those will use a bus, even if it is overall faster (better route, etc.). Driverless cars are likely to provide a reasonable working environment.
