Do you have a link? What’s the best venue? TomTom, OpenMaps? I have one area that does exactly what the “Hyperbole Guy” did (minus the over the river and through the woods to Gramdmas house we go bit). It’s done it 2 or 3 times. What was crazy is the first time (which caught me by surprise) was it actually turned on the left turn signal first (with no left turnoff on a double yellow burb back road) before it departed so at least I had a warning.Check the map in those areas. Won’t be surprised if it’s a mapping issue.
If there were cars coming in the opposite lane, it is unlikely the car would have switched lanes.
