Yet another Google Maps fan post — the predictive traffic feature

Google Maps users (including those who use it via the iPhone) probably know the service provides real-time traffic data for 30 U.S. cities, including my hometown, Nashville, where there appear to be a few fender-benders today. For a view of some nightmare traffic, here is the other city I spend lots of time in, Washington, D.C..

Now, if you click on the “change” link while the Traffic layer is visible, you can view a predictive version of the Map that, as in the example below, suggests what the traffic will be like at 4:30 this afternoon. The predictions are based on historical data.
