If you have to take a turn or follow a (different) particular road often, you can calculate your route using Via Michelin and look at the details. It will say how long you'll have been driving already at every action/turn you'll have to take. Then you only have to add that time to the time you will leave and look into the details where you'll be at that time.
If your trip doesn't generate enough details, it's maybe too hard to tell what city you'll be in. But I hope it will suffice, if nothing better pops up.
