Back when I used google maps, I especially hated its insistence on making unprotected left turns. If I knew the area it was taking me to, I would scan ahead for those and try to avoid them, but there were some terrifying times where I pulled up to a busy 5 or 6 lane stroad expected to turn left. I invariably turned right and took an alternate path, for the safety and comfort of everyone (except my map, which would scramble to figure out why I had done something so stupid).
