I enjoy AP but freak out when a car in front of me is stopped at a light and I am going at a high rate of speed. I find it stops to abruptly. Going 50 miles per hour waiting for it to slow down 500 feet away (radar engagement) is scary. I have started using the stalk to drop the speed from maybe 50 down to 40 mph in 5 mph increments. This is a little more comforting.
