So, you haven't clicked on any of the several links in this thread to Sandy Munro with the Ford rep in the passenger seat as a slight bend in the highway turns off the Blue Snooze autopilot while they were chatting?I hear the ford autopilot is quite nice on the machE on highways. All I've heard. The GM product in cadillac is supposed to be nice from what I hear. Again, I have never seen it. I hope they all show that these systems beat the heck out of cars with no systems.
Ford rep then says something like, "It is designed to disengage on sharp turns" or some such nonsense. It was the slightest of bends on a busy multi-lane highway. No prior warning, it just disengages and the car starts heading toward the adjacent lane and Sandy caught it in time.
It seems to me that "using no system" would perform better than any driver assist that resorts to a "pure physics" pilot mode when confronted with anything beyond a straight road ahead, potentially sending an inattentive driver across occupied lanes without warning.
