My Commute was supposed to learn from your driving habbits and traffic information to help you plan your commute more efficiently. The app on my Lumia 900 would usually pick a route that was slightly slower however less congested. There would be some stop and go and in reality I saved only a few minutes drive time. I'm hoping that updates to the application would give it more real-time information and better logging of your driving information to determine the best route/routes for your travels.
