You don't need to send the data to cars for wi-fi equipped traffic lights to be useful.
I can imagine hooking up a traffic light with both a wi-fi device and cameras to measure traffic flow. Traffic light A could communicate with traffic light B to let each one know how much traffic was on the way to the other light, so that it could adjust its programming. If you did this on a large scale, I would expect it to reduce traffic by a lot.
Of course, I don't know if the reduction in traffic would be greater than the cost of equipping all traffic lights with wi-fi devices and cameras.

But if you can measure traffic flow passing through one intersection, can't you measure traffic approaching another? It seems that the way to start implementing would be to improve nodes first. Connecting them seems a bigger, more political job.
