I'm considering purchasing a refreshed 2022 AT4 with the 3L Duramax with adaptive cruise control (ACC). The problem is there aren't any on dealer lots near me to test drive. I've looked at a couple of YouTube videos showing the adaptive cruise control in the GMC Sierra but none of the videos are in slow traffic. I was wondering what has been anyone's experience with ACC in slow or stop and go traffic. I'd appreciate any input. Thanks!
