I’ve had something like this happening to me a long time ago. While going from a city in Uruguay to a city in Argentina, Google Maps “suggested” a route that was 2 hours longer but took me through the ferry (a paid business). Even though I chose “keep my route” several times, from time to time, the suggestion popped up with a “time limit” to confirm. If I failed to notice it, the suggested route would be selected.
Different studies. INDEC measured 41% last December.
