They detect a lot of things they choose not to display. They also choose to display stuff they recognize poorly (cue in the dancing cars).AP has been using cones to limit driveable space for quite some time now (spring time?) Which means it see’s them. HW3 will now display them, which tells me they have more confidence in visualizing individual cones AND HW3 will do a lane change to move away from incoming cones. 2.5 will not.
So basing your assumptions about their state of detection on what they chose to display or not does not sound as a very good idea to me.
