I often travel to Italy from Switzerland and vice versa, in Switzerland to use the highway you have to buy a sticker (or register your license plate online since this August) and pay a set fee for the year while Italy uses toll booths.
If I choose "avoid tolls" on Google Maps ALL the Swiss highways are excluded while in Italy Maps will tell you to use them for section where toll booths are not present. If I allow tolls the highway system of both countries is allowed.
Let's say I already have a Swiss sticker but don't want to pay the tolls in Italy (or I don't care about the Italian toll booths but I don't want to buy the yearly Swiss sticker for just one trip). Right now the only way I have found is to allow (or disallow) tolls, stop when crossing the border, disallow (or allow) tolls again and wait for the route to be recomputed.
Is there a way to tell Google Maps E.G. "Allow tolls but only for this country"?
