It would be very fine if the color of the route would be special. A color, that you can't find in the map .... maybe violett.
(the blue one is like a "river" color)

If you make a route an you set the point on the wrong side of an motorway, the routing always tries to reach that point.
It would be fine if the routing app could "see" this mistake an clear the problem.

Thanks
