My Commute, as we explained in a news post, was a headline feature addition to Nokia Drive 3.0:
Nokia Drive's new "My Commute" monitors your regularly driven route (e.g. work commute, school run) and helps you make better decisions about which route to take, taking into account live traffic information (i.e. delays cased by accidents and congestion). The app does this by learning about the routes you like to take and will anticipate your driving habits (e.g. which two main roads you take on your morning commute).
The Nokia Drive tile on the home screen integrates with the My Commute functionality, indicating when there is information about a commute available (front side), and will flip to show a destination and estimated commute time. The estimated commute time is based on how long the journey takes and the projected traffic conditions during your usual commute time.
Tapping on the Live Tile will start Nokia Drive and drop you into a screen, with two commute route options displayed on screen (based on routes you've previously used). Nokia Drive will automatically choose the fastest option and tapping on the "commute" button starts the navigation functionality, with on screen and voice turn-by-turn instructions.
The My Commute feature is dependent on accurate traffic information and, in some cases, needs market specific adjustments. This puts a limit on the number of markets, and the speed with which, the My Commute feature can be rolled out in. The countries for which Nokia has traffic data, and are therefore potential candidates for the My Commute feature, include Austria, Belgium, Brazil, Canada, Denmark, Finland, France, Greece, India, Indonesia, Ireland, Luxembourg, Mexico, Netherlands, Norway, Poland, Portugal, Saudi Arabia, South Africa, Spain, Sweden, Switzerland, and the UAE. It's notable that the market Nokia has chosen to roll out the service in, are those with among those with the largest install base of Nokia Lumia users.
