When you first started using a cell phone did you imagine that one day it might be used to help develop traffic reports? Google has figured this out. You can get some details in the google blog here: "The bright side of sitting in traffic: Crowdsourcing road congestion data."

Reading about this, I get a dreamy kind of feeling. If they can do this, what other sort of possiblities lay ahead? Of course some direct implications would be using this data for better planning of future road improvments. But we can also think about adaptive highways, where the road, detecting this congestion, would open a lane.  Many good uses can be invisioned. Police and fire personnel could respond to accidents faster, etc.

It seems a limitless horizon where we have only scratched the surface of what we are capable of.
