I just came back from a 1300+ miles round trip between Atlanta, GA and Ft. Lauderdale, FL. About 60% of the drive was day time and 40% of the drive was after sunset. My AP HW is 1.0 and SW is 2017.28 c528869. Overall experience was better than a couple shorter trips I had before in an earlier software version. The Autosteering this time was smoother in general and notably when road ahead ramp up and down. In the past, the car would ping pong between the lane mark every time a small hill coming up ahead. There were still occasional ping-ponging within lane marks that seemed very random. And sometimes during a turn it would grab the outer lane mark too close. It got scary a couple times when there was a semi in the next lane ahead of me. It did quickly corrected itself but the steering was not comfortable in such situation. I did notice for the same road condition, Autosteering performed better (less ping-ponging) on the most left lane vs. mid-lane. I am not sure this was because the solid line on the left was easier to recognize vs. dotted line on both sides in the middle lane. I also notice in the dark environment, Autosteering seemed more confident with high beam on vs. off. It does seem to predict the lane better when the light was projected further. Close to the end of trip, the car started to have trouble recognizing lane mark intermittently. I disengaged AP and restarted both screens and this problem went away. I wonder if there was a computer power problem that AP2.0 and 2.5 already resolved. But man, it's annoying. Overall, I love AP and it helped reduce my fatigue significantly. I do think the limited HW on AP1.0 made it harder to become significantly better than its current capabilities.
