This has not been my experience. Twice, on the first full day I had 8.0, my AP was disabled (had to pull over and put in park) without any audible warnings. I'm not saying that's how it's supposed to work, but that's what happened to me. I have mitigated the problem by changing my hand position on the wheel to a point where I'm applying more torque. I don't get any nags as long as I leave my hand there (roughly 10 o'clock position). It's not as comfortable, but it works. As for the general performance of auto-steer, 8.0 is not significantly different in my car than later versions of 7.1. Earlier versions of 7.1 were superior to both. I'm not getting the sharp swerve to the right that some are reporting, but my car loses the lanes at times when there is no obvious reason for it. This occurs on stretches of road that I drive every day and on which the car used to perform flawlessly. I think as they get more data feedback from the fleet using the radar as the primary sensor, AP performance will improve. Also, things are going to be in flux until the regulatory scheme catches up to the technology (which could be a while). I got a thumbs up from a guy on the highway yesterday that reminded me how happy I am to be able to take part in these discussions. Still really love my car.
