Buses GPS

I've been thinking about this for a while. One of my fondest experiences with GPS is knowing exactly how long I have to wait for a bus or train (or any type of public transportation, for that matter). I think such implementations are especially useful for remote bus stops where you're never quite sure if the bus is really going to show up. Something about the time steadily counting down offers a bit of reassurance which makes waiting for your ride a little bit more bearable.
