On a route I take every day, Waze will switch up the routing at this point:https://www.waze.com/editor/?lon=-71.18367&lat=42.33987&zoom=5&layers=BFTFFTTTTTTFTTTTTTTTTFT''
Some days it correctly routes to take a right at that intersection, and then an immediate left. But other days (and today) it creates a very roundabout route for no apparant reason. All the turn restrictions seem right to me, and the right turn would be onto a primary street, as opposed to the roundabout way on regular streets.
Any ideas? I don't think it's a GPS problem, since this happens about 50% of the time.
