I picked up my new P100D from the Dallas service center in December. I have been driving a P85D for two years and was very pleased with the performance of the autopilot. So far my experience with the new hardware has not been great. I'm wondering now, if it has something to do with the software still advancing or if maybe I have an issue with my particular vehicle? The problem that I've noticed from the beginning, which has become much more pronounced at higher speeds, is that the lane lines on the screen are constantly shifting/moving. Even when I am at a complete standstill they are moving to the right and left. While driving, this translates into a constant shifting within the lane (and sometimes across the lane). The system is particularly unreliable when heading up a rise in the road or when encountering shadows. Just wondering if anyone else is noticing this or if I might have a problem with my existing camera and hardware? As a long time Tesla fan, I don't mind being patient as they roll out upgrades. However, now that they have increased the auto pilot highway speed to 80 mph, and my system is still dangerously unreliable, I'm wondering if I have a problem? Any thoughts or comments would be appreciated.
