MobileTraffic.tv: See Live Traffic Cameras
I've been dreaming of a service like this. MobileTraffic.tv gives you access to live traffic cameras around the globe. This way, you can see the highways, exits and intersections during your daily commute or for planning a trip to avoid backups and infuriating traffic jams. Of course, you'll want to avoid browsing while you drive, but check it out before you leave the house.
