I'll admit at one point I just upped all the PA/ACC stuff (on my '23 V60 PE) to whatever the highest level is for awhile. It worked just fine, no errors and hundreds of miles without incident. I recently reverted the config to stock to get service and used the ACC on the way, and it felt "better". I can't really describe how, just more situated. I think there was less hunting between the lines, it seemed to actually follow closer, and the braking seemed smoother.
That got me thinking of possible reasons. One idea that stuck out in my head is that maybe the "levels" are related to the size of the vehicle for PA/ACC calculations. I wonder if by changing to a higher level I made the system think it was a different sized model. This could cause issues with lane hunting as the software doesn't know the car isn't as wide as it thinks it is, so it's constantly trying to "fill" the middle of the lane with the wrong sized car. On top, the following distance would probably be increased for a heavier vehicle as it would take longer to come to a complete stop.
I wish I could browse all of the default config data Orbit has pulled from cars to compare and see if there is a trend or "default" collection of settings for certain features or models.
I think you raise some very good questions and I would be interested to learn more on the lane keep and ACC values as well. Not sure about the theory on lane centering as the center of the lane doesn't change with the size of the vehicle but braking and following distance certainly could. I have played with the different levels of Pilot Assist and have not found a difference, they all want to bias to the left for whatever reason; so I always feel too close to the center in heavy traffic.
