I have a 41 mile commute (one way) over a ton of blind hills (where I lose sight until driving over the crest) and sharp curves in western Pennsylvania that I use autopilot HW1 for 90% of the drive. I have been recording my drive with each update and noticed improvements here and there. The car still pull to the extreme right or left, crossing the line and forcing a takeover when going over some of these hills, unless following another vehicle, and there are two curves where it forces a takeover on its own. Today, after the 8.0 (2.52.22) update, I noticed some new behaviors. It slows down and handles sharp turns much more gracefully, and although there are three beeps (a new tone I've never heard before) AP stays engaged and asks for a nudge on the wheel instead of disengaging. The most surprising thing was that there was a section of curved and straight road that was covered in salt and no lines could be detected for about half a mile. There was no vehicle in front of me and the autopilot display on the dash showed a dark grey road with no lines but continued to follow the road in and out of curves, flawlessly. I was not recording my trip home (when it happened) but I will tomorrow. The hills, I'm sorry to say have the same behavior and it seems that roads with lines on the left and a curb, sidewalk, or grass on the right have gotten "worse" as the vehicle really hugs the right where i'm afraid the wheels are going to scrape the curb. The vehicle used to stay smack-dab in the middle under these conditions. Anyone else find any new behaviors on there normal route?
