The lane divider on the right is also quite visible; considering that its internal maps should tell it the road has a left exit, I'd expect that it should be able to guess that it should be holding to the right edge instead of the left edge of the lane.
This does bring up a theory: the lane keeping is biased towards holding itself to the left edge of lanes, on the basis that most exits are right exits and therefore the right edge will tend to diverge a ways before making a new lane. I'm curious how it would handle the split at the mixing bowl in Springfield, VA: https://www.google.com/maps/@38.7735345,-77.1816237,3a,19.8y... (functionally a left exit, although signed as if it were a right exit). The solid white line doesn't actually denote any lane exit boundaries there...
