When I pass a vehicle on the highway I accelerate, get in the passing lane, pass the vehicle, get back back over into the right lane, maintain passing speed to put some space between me and the vehicle I just passed. Then let off the gas and coast down to the previous set speed. The system in this car applies the brakes as soon as you get off the gas. Very annoying. My first experience with these so called driver assistance systems was years ago. I had to take the company van to customer site. The car up ahead of me got off on an exit ramp that curved along with the highway, and when it slowed at the end of the ramp, the system in the van decided to jam on the brakes full force at 70mph with no warning. If there was ice on the road that day I would have been dead. The Chrysler 300 I traded for this car had both normal and adaptive cruise. Never used the adaptive cruise. I also shut off the automatic emergency braking after the first time it smashed on the brakes because it thought I was going to hit something.
