Automated breaking is a great idea in principle, I’ve had it on the last 4 cars (2 x VW, Jag and now the Audi A6).
The A6 is definitely the most keen, and has applied the brakes about 5-6 time unnecessarily in the last 3 months, albeit I could see why it did. Usually a car parked at the roadside or overtaking a bike has triggered it, but I have given plenty of room. It is verging on dangerous and frightens the life out of you when it jolts the brakes on suddenly.
Never had any problems with the Jag, or the VW Passat, but had a Golf R that was nearly as sensitive.
I’ve set everything to low sensitivity in the settings, I assume you have?
With regard to the hands on the steering and lane warning, never had any of those. Again I turn off lane departure every trip, can’t stand it.
