There's an old roundabout in my neighborhood that's used like a speed bump; there's no left or right exits, just straight. The nav line goes straight through, and the car tries to drive straight through the center, which has some trees, a boulder, and a flagpole. The roundabout has existed for at least 10 years. I've already checked OSM and TomTom and they both show the roundabout. Reported a bunch when that was still an option.
Pretty sure originally that roundabout was a dead end cul-de-sac, and later they extended the road without eliminating the circle.
Can't wait for Tesla to fleetsource mapping.
