alt Hacker NewsI don't really understand, don't you just go out of your house, go to a bus-stop and wait for the next one? Isn't the bus arrival display more of a convenience to know how long to wait? For the bus stop in my neighborhood I see busses every couple of minutes.
You're very lucky to have high frequency transit. I've lived in several places (in cities) where the bus routes ran every 20-30 minutes. So if you don't feel like waiting at a bus stop for 20 minutes, often these days one without any seats, it's nice to be able to check the ETA.
