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.”
It could also be a nearby break in the internal road definition. I know for some places, Google Maps will randomly start saying “continue on X road for 23 miles” every so often even when there are no obvious reasons.
Or maybe it’s because it keeps losing and reacquiring GPS signal. I haven’t messed with it when it’s happening because I’m driving.
