Not sure I see the point. In AP1 it would show me cars in front of me and cars to the front side right and left, each of which are already in my vision. Other than the "look, it sees the cars" factor, it provides no benefit. In AP2 it clearly sees the other cars, as is demonstrated when you engage the turn signal. Then it shows them all. I have just assumed it was a UI choice and frankly it is less distracting this way. It shows the other cars when maybe I need to see them. When it changes to push my car further forward and shows cars coming up in my blind spot.....then I will care. But I could be missing something. Or not.
