The cruise control and steering assist system have no idea what it means to gradually slow down or what to do on a slight hill approach. It also watches the vehicle in the right adjacent lane too much. For instance, on a 3-lane road, I will be driving the speed set on the cruise control but if a car in the right lane exits the highway, the car will brake like the vehicle is directly in front of it. It seems like a safety issue when the traffic behind me sees me slowing down for no reason at all. The cruise control also thinks an approaching hill is a car and will perform an emergency braking maneuver when all that is happening is that the vehicle is approaching an uphill grade.
