So in other words, if there's a traffic jam, then the displays could read something like: "next bus:
3 hours", if it calculates solely based on current speeds/positions? Fun. I guess it'd have to be a
bit smarteer than that though.
Actually, this might also eventually be a good way for the corpo to analyse traffic flow through the
city, as they'll be getting in real-time data on where teh choke-points are.
