Ive a Jeep Grand Cherokee. It has the front sensing collision detector and auto braking. It may have hit the brakes 1 time that I wasnt paying attention and 9,999,999 times when there was nothing in front of me. I disable it and thus far have avoided crashing. The point is that driver assist systems are only assist and you have to pay attention when you drive. Ive said this here before, Autopilot is a terrible misnomer. It seems to sit squarely in the valley of being good enough to 'trust' but not good enough for real world use. If I were in charge of the world, it would be rebranded immediately.
