A Widget for Real-Time Auto Traffic Information [updated]

The Apple Technology Laboratory (Laboratoire SUPINFO des technologies Apple) offers a new version of the Widget entitled "France traffic". Of course it only covers France, and is for the time being only localized in French, however, we would like to know if similar useful widgets are available for other countries. "France traffic" provides information about traffic jams, problems on the highway, etc in a real time manner, and one can even have detailed information for 12 large cities.

Once implemented in an iPhone, this widget will simply become a "must have", and might be the type of applications that consumers needs to be available or developed for purchasing an iPhone.
