This is due to the fact is must be set from factory as if folks were able to add it later and you had a crash, audi would be part responsible....if you get what I mean.
The apportioning of blame in the event of driving aid(s) failure is interesting.
My car has lane assist and, unknown to me, it was switched on when I drove the car out of the showroom. It took me a while to realise why the steering was fighting back on rural roads, some with a white line on the left.
The system is not perfect either.
On a wet 3 lane motorway I drove through a section where there had previously been some road works and a temporary cross over to the other carriageway. When the cross over was in operation, temporary "cats-eyes" had been stuck to the road to guide traffic.
Those "cats-eyes" had been removed but the square patches where they had been glued down reflected light differently, in the wet conditions, to the rest of the road surface.
At 70mph, the lane assist camera picked up those square patches and the steering tried to follow the route of the now blocked off cross over! That was somewhat unexpected!!
Lane assist has been switched off ever since.
