If you're choosing a route , waze suggests it always under the aspect of as-fast-as-possible aspects. I got time and am looking for a route under sightseeing aspects, For me it does'nt matter if the route lasts 2 hours longer. i'll make a rest in a nice littel town in a café and are enjoying the landscape.
So we have to use our analog paper map, waze is not really helpfull.
Please give the possibility, to choose a route under touristic aspects.
