Active Track Keeper – Experience and Function

Hello together, for 2 weeks we have our new ceed (1.4 SW GT-Line, switch) and so far we are also very satisfied. However, I personally can not see any real benefit of the active lane stop assistant. I have to say that we drive to 80% of the country road. Sometimes he does not recognize the track, although the road is flawless, then he recognizes one where not even I can really see strokes on the road. But the worst thing is that here we land roads without middle line and it often happens that the assistant wants to steer into the middle of the road – what I think is quite dangerous at over 100km/h. Somehow it only bothers me while driving. Sure, in an emergency situation it could prevent worse, but now I deactivate it immediately. Is the system really only good for the highway to use, or do I do something wrong?
