The cruise control is adaptive.
If it wasn't adaptive, I'd be worried about adjusting 1 mph or so just to avoid the annoyance of being just a HAIR faster than the car in front of me and having to slow down. With it being adaptive you just set it and going up or down 5 mph just makes it faster to adjust your target based on speed limit changes. It makes a heck of a lot more sense in my mind given the ability to auto adjust speed for traffic.
