I have a 2020 Silverado High Country, and I use Adaptive Cruise all the time and Love it!!! BUT!!!
It is like all technology, it has its limitations. I have had mine disable in direct sunlight and pouring rain.
the worst condition is nearing a red light in a 4 lane where the car in front of you moves over to the other lane.
even if there is a car in front of where that one was, the truck guns the accelerator to regain the cruising speed, right toward another car or an empty lane with a red light. Give me a software update so the Adaptive Cruise Camera can recognize red lights and stop signs! JK
all that said, I will continue to use the Adaptive Cruise. It works most of the time. the limitations are in the single camera and the software.
