I use MSN Traffic Alerts to keep abreast of traffic info in the area. It's rare that I'm impacted by traffic, but always helps when I go into Chicago.
Yesterday during the big storm I kept getting timely alerts on road closings, major accidents, etc around Michigan City. Very helpful as I made my way to and from Spencer's grandparents house the next county over.
Also more impressed with Quattro than I have ever been. Actually pushed a stuck Hyundai out of a bad spot yesterday, and did not get stuck myself. That's sweet.
