'why I am asking: the ACC functionality I don't like. If I drive (on German Autobahn) 160km/h on the left side and going into a left curve, on the right side is a truck - the RRS will slow down strongly.. I find it quite dangerous on such velocities.. '


Yes, I find this situation occuring in hairpin bends as well. Although I'm not going nearly as fast as on the autobahn, the car will brake heavily from 80kmh - the traffic behind you doesn't expect it, and it can be quite dangerous. --

Thank you
I also now have a "technique"... if you keep a proper angle with the steering wheel, it will not brake. So if you have to correct a little bit, it can brake.
In sum I can handle it better then a year before.

My dad has a Volvo also with ACC. I tried and it brakes also... Range Rover Sport HST D350
