This is cool. Google Maps helps make your drive a little better and maybe a little more efficient.

Google says.

There’s nothing worse than getting stuck in traffic when you have some place to go, so I’m happy to tell you about a new feature on Google Maps that can help. For more than 30 major U.S. cities, you can now see up-to-date traffic conditions to help you plan your schedule and route. If you’re in San Francisco, New York , Chicago, Dallas, or any of the other cities we now include, just click on the traffic button to show current traffic speeds directly on the map. If your route shows red, you’re looking at a stop-and-go commute; yellow, you could be a little late for dinner; green, you’ve got smooth sailing.

Check out New York City. This may help save gas by allowing drivers to go out when the traffic is better. Of course, Google Maps also shows subway and bus routes for some cities.
