2. Immediately your map will update the route you have submitted.
3. The title of the page will tell you how many possible routes exists ( The inverse route is not counted in this figure, since it’s the same duration and distance).
4. The position in relation to all possible routes will be updated (position in terms of duration, not distance). The duration and distance of the trip will also be update.
