One great feature of ACC that I stumbled into. My son was following me home from hunting camp and I was pulling our trailer. I was speeding up on downhills and slowing down on corners and uphills. He was able to just set it and forget it and stay at a nice even distance from me the whole time without doing anything. So, when following someone, you let them set their cruise to whatever and you just overshoot their speed but let the ACC keep you right on their butt effortlessly.
That's really the main way I use my ACC. I set it to a few MPH faster than the traffic and set my follow distance. It will bring me to a full stop and resume, if I sit for a while I have to tap the speed controller up and it resumes from a stop. The only time I don't like it is in hilly terrain or when someone gets in front of me. It kills the momentum, which is where the lower MPG comes from, whereas I could have judged it safe to just keep going and maintain my speed before the hill or knew that person was clearing my lane.
