However, PA is behaving very badly, can't even hold in the center; on small curves, it just goes over the line, making usage very dangerous. Lane keeping assist detects the line extremely well, but when using PA it just misbehaves. I have tried recalibrating the cameras from Orbit, but I am not sure if it is just for 360 cameras or also for PA. I don't know what else to do; this option is very useful for me, but constantly having to think if it will go over the lane is awful.

Did anybody have a similar experience? Is it possible to solve it somehow?



P.S. The car is 100% maintained properly; no DTCs related to any of those systems used.

And it does likes to keep a bit towards the edge of the road rather than to the middle, to stay away from opposing traffic.

It did feel worse for a while right after changing my windscreen, but since the system self adapts, it has gotten somewhat better than it was right after the swap.

These are my experiences at least, so it can vary of course.

I recognize that the system is not designed for self-driving, yet on a brand-new highway it should at least remain between the lines, which it fails to do. My vehicle does the opposite, tending toward the center.

@Entropy: Much like my situation, the system drifts across lanes during ping-pong even on straight highways. On ordinary roads with a slight curve requiring a two- or three-degree adjustment, I cannot predict whether it will steer or veer into oncoming traffic.

Yet, some people claiming they are using water bottle on steering wheel and the car drives itself nicely. There is even videos on youtube. I believe there must be some software update that we are missing...

Bit worse on the country roads that has an exit / off-ramp, where it loves to try to follow the exit rather than the main road.
