Once activated, how do others find the motorway ACC/lane assist experience? I do very little motorway driving and keep lane assist off most of the time. When I am on the motorway and engage ACC and lane assist I really struggle to trust the lane keep as it seems unable to stay centred(ish) in the lane, instead behaving more like sliding toward one side of the lane, then over-correcting to a gentle slide toward the other side of the lane. It's not savage over-correction, but it's unnerving that it doesn't just find the centre and stay more or less there.
How does it behave for you? How relaxed are you with it on?
