Why not have a simple geolocation service that matched where you're going with people in cars that will be going your direction soon? Twitter that you want to go cross-town and in seconds you get a half dozen dynamically updated commuters that are going your way. Combine this with point-by-point gps instructions from point A to B, the commuter you select gets routing information that allows them to stop at an intersection and honk to let you know your ride is here. The service consists of three parts: (1) where you're going (and where you are via GPS) (2) a back end database that can figure out from all the real-time information who matches up (3) let you choose from the options - maybe based on the kind of car, their reputation/reliability, etc. Not too hard - in fact either Twitter or FriendFeed could be a big hunk of this business.
If geolocation and routing allowed people with cars to pick up people with minimum inconvenience, and if enough people with iPhone 3G-type phones could get streamed updated directions, and if there was a simple way to establish reputation, this could change how people commute and travel in cities, saving a tremendous amount of energy.
