Google inventing new navigation system for cars?

I have made no secret of how much I am enjoying my Garmin iQue 3600 with built-in GPS and routing software. Well, it appears Google is about to do us one better by releasing a new automobile navigation system which integrates GPS, Google Earth, and their other information mapping software to provide Volkswagen drivers with real-time routing, traffic problem alerts, weather, and other critical driving information. If they can pull it off, it is a great idea. My Garmin is wonderful, but it would be even better with the ability to route me around the worst parts of a snowstorm or warn me before I have reached the traffic jam that is 10 minutes ahead of me.
