I'm on AP1 so I may be getting this sooner than AP2 cars? some improvements that I've noticed are: 1. It locks on to cars much further down the road now, (looks like a small blue dot on the screen), I noticed this yesterday when I was driving down a road damaged by winter weather and most of the lines were gone...It was tracking a car that was at least 200' in front of me! 2. It seems to be "looking" further down the road in general as I drive in AP with my distance set to 1 car length and it seems to start slowing down much sooner now rather than racing up on stopped cars when at a stoplight or traffic. 3. It does much better on badly marked roads or roads with no lane markings even when there's no car for it to lock on to, doing better noticing curbs and seems to be using GPS/Maps/Camera combined to take me down the road. (I will have to post a video tomorrow when I go back down this road, which isn't all the way straight!) You can see below that there are no road lines shown and it's not locked on the car in front of me, (the car would be blue if it was locked in), but doing a fantastic job keeping me going down the road.
