I've been travelling cross country for the past three days and have spent a lot more time with adaptive CC. I must say that it works a lot better than my '14 did. Acceleration and deceleration aren't as abrupt. I've also noticed that when you've caught up to someone and slowed to their speed, when you go to change lanes, the car accelerates as soon as you signal to pull out. It doesn't wait until the car is no longer in front of you. If you don't signal, it doesn't do this.
