Here is a Windows Sidebar gadget from the Windows 7 Personalization Gallery that can give you a head start on your drive into work each morning.
This gadget provides a snapshot on your desktop of the current traffic status on your city provided by Bing and gives you direct access to Bings main traffic website to look into traffic details more in depth before you walk out the door.
The only limitation on this sidebar gadget is the number of cities covered which is a limitation of Bing Traffic itself. Currently only 93 cities are listed but it is quite popular as it has been downloaded nearly 840K times.
