Original toot in Spanish says: “OK, so I need some alternatives to Google Maps, because I just decided seconds ago to stop using it after I got proposed a trip with a completely unnecessary detour which adds two extra minutes just because it pass by a gas station that sponsors this trip.”
Does waze have a fuel saving mode? It might be sending you down an exit because the route uses less fuel. I doubt waze and google maps has enough users to cause too much traffic. Surely most people drive familiar routes. I could be wrong.
