Autopilot certainly takes map data into account when available and to improve confidence of detections.
You can see it really well in less mapped locations. Like that South Carolina video where you can observe high correlation for mapped side streets (as seen on the side map) to show a lot further away from in the visualization, being a lot less jittery and stay on as they are passed vs the unmapped that appear only super close and disapear as they get out of view of the wide-angle cam.
The vision code now has map inputs into some NNs in addition to radar inputs that certainly helps explain this.
need a frame in-between, I think the left side of the other side shows what is a crosswalk. It appears the mapping displayed is not entirely "blind" but instead it still wants at least some faint confirmation before it shows a feature (but if it's not on a map it wants a much-much better view of it than just a hint)
I tried to outline what a possible hint might be that's enough in face of good maps, but not enough when there's no maps.
