I like using the Adaptive Cruise in city driving. But, one thing I find is that it waits to start slowing down much later than I would if I was in control. It brakes harder/later than I want to. To help combat this, I actually used the following distance buttons more. For normal city driving, following distance 2 is "normal" for where I live. But, when I see a red light in the near distance, I change it up to level 4 - so that my car starts slowing sooner. Then, when we're moving again, I go back to follow level 2.
