I do not drive much (12k km per year) and this is 80% on roads I know. The remaining 20% is the road to vacation, usually with everyone in my region going to the same spots (this is in France). I am always wondering how good these apps are in such circumstances, when on a specific day everyone goes to the same place. They do not synchronize, which would help people to drive different roads from the start. Last Saturday I drove from Paris to the Alps, together with everybody else. GM was suggesting the straight road (A6) and I decided to take a completely different one (A5 via Annecy), supposedly 1h30 longer (over an official 7h30 trip). I arrived me of les at the same time as the others, with less stress (not one traffic jam). I would love to have an app which talks with the others to suggest an alternate road "because the others are PLANNING to take the obvious one"

Google predicts traffic in the future when deciding which route is best. That prediction will lead to users being spread across different routes.

  Ah? This is interesting and a very good thing - it may not be deployed everywhere, perhaps? I use mostly GM and the suggested road shows traffic being slow or fast "as we speak". The image, from the same place, will be vastly different at another time. And I see that in these times the road is different, avoiding the hot spots as of now. In other words: - at 5 in the morning it will route me through a busy town 500 km down the road because there is no traffic now. - at 17:00, from the same starting point, it will avoid the same city, because of high traffic. This high traffic is irrelevant to me as I will hit the town in 7 hours, when there will be nobody on the roads.

    It's actually a complex one, and a constant source of user complaints. The coloring shown, and delay markers, are as the traffic is now. The actual route planning is done with data as the traffic is predicted to be.
