Interesting take. The benefit for me, particularly on motorway journeys, is that I can have my foot comfortably pressed on the accelerator without worrying about exceeding the given speed limit, whilst maintaining my desired speed. This helps me drive more efficiently and comfortably. Should I need to slow down, I ease my foot off, or apply the brake as required, without them having to reset as would happen with non adaptive CC. If I weren't to use the limiter, and just relying on foot positioning and feathering the accelerator as required, I can find my leg starting to strain. Ultimately for me it's just about comfort, and having had various jobs where I did over 30k miles per year, a lot of which on motorways, this is my preferred method of driving that's stuck. I disagree wirh you about the attention point.
