Your use of the word "it" has now confused me more than ever. What is now smoother? Lane to lane wobbliness or?

Yes less ping pong wobbliness

Example: With steering in comfort and Adaptive cruise not in sport mode. I tend to see the car drift to a line … overcompensate and drift to opposite line … then overcompensate and drift to the original line (ping pong drifting).

With drive control in Auto or Dynamic (so steering not in comfort I would assume) … then with Adaptive Cruise control set into sport mode. The car will drift toward line … move back slightly off the line …. then hold the the line pretty well (near center of lane) and never drift as far as the opposite line.

I think where I had been disappointed in past is … being on highway I think Comfort as drive setting should be best so I've always been in Comfort when testing (I'm leaving in Auto now on highway). Then of course I have no idea what parameters having Adaptive Cruise in sport changes … but it seems to definitely improve responsiveness.

Thanks. This detail is very helpful. I went from wanting to now buy the driver's assistance package in my D5 to now going back and thanking myself I didn't buy it.

I would not run the car in any mode other than comfort, so while good for the community here that you learned something new (And thanks for sharing), it doesn't help me, sadly. Oh well.

Auto drive mode seems to be good for highway and works well with what I want.

Personally - I wouldn't get an Audi without driver assist. When I talk about the ping ponging - this is in extreme cases where paying no attention to steering. You should keep your hand on the wheel not do as I'm testing and with hand on wheel no matter what mode it is great for keeping you in lanes. With hand on wheel the car doesn't overcompensate. Its only with light touch or no hand on steering wheel that what I'm talking about even applies. Driving down the highway with lane keep and adaptive cruise control makes interstate driving very enjoyable.

For sure. My other beef with the driver's assistance packages of 2019 have more to do with other variables not concerning ping ponging. That just adds to it.

Thanks for the very informative post. After applying your recommended settings my Q8 Lane Guidance behaves exactly as you describe which is a big improvement! Unfortunately, the abrupt swerves off the road remain unless I disable Lane Guidance completely. The latter is a bigger problem and a safety hazard. It also seems dumber than dirt to have to set particular DAS settings to get Lane Guidance to work properly. What I found interesting is that the inexplicable loss of lane perimeter markings does not appear to affect Lane Guidance with your settings. From your findings, my guess is that there is a simple firmware fix or fixes. Thanks again!

Luckily I never experience the abrupt swerve in this car or my S6 prior.

Well your settings looked good for a while, but I am not getting consistent results due to what appears to be the option lighting conditions. The other thing I noticed is that in the Sport mode the car accelerates much more quickly to the detriment of mileage. I have been keeping Lane Guidance disabled which is the most comfortable for me. Its a shame Audi won't fix the Lane Guidance so that it works properly under all settings! We all paid for it. Thanks for the information though!

I noticed today that driving down the exact same road at night yields completely different Lane Guidance results than daytime:
1. At night, there is never a displayed loss of lane perimeter markings; always green
2. At night, the vehicle tracks down the exact center of the lane with absolutely no ping pong
3. Tracking around curves is right on the money
4. At night, the Lane Guidance performance is virtually perfect
I don't have access to the semi-autonomous feature technical details, but the daytime problems could be something as simple as the wrong f-stop setting on the camera(s), thereby reducing contrast below what it needs to be. At night, the headlights reflecting off the lines could make the difference. I noticed this phenomenon before, but didn't do an apples to apples comparison between day and night driving. The lane markings on the road are very clear with no debris or other obstructions.
