At any time you can cancel auto lane change by simply tapping the turn signal. So if you have auto lane change on amd the truck engages a lane change you can tap the turn signal and cancel the lane change. There’s a 3 second delay from the time auto lane change engages til it starts to lane change so plenty of time to cancel if there’s a vehicle coming from behind too fast.

This video is such a wealth of information on SuperCruise. I am considering a GM vehicle for the first time, just for SuperCruise. This video answered so many of my questions. Driving on 2 lane rural highways will be a big part of my usage, and I was very hesitant earlier because all available information said SuperCruise only works on divided highways. Seeing SuperCruise work on 2 lane highways seals the deal for me.

The road noise in there sounds awfully loud
