This is the problem with automation, what happens with technical failure. Although cars travel at a fraction of the speed of airplanes, the demands for a car are one hundred fold, because instead of having a several mile cushion, you have as small as a 10' cushion, such as on a narrow two lane road, with opposite traffic, and up to 140mph closure. It's like depending on technology to thread the eye of the needle, and your life depending on what happens when there is a malfunction.
With peoples phone and movie distractions, being complacent, and not paying proper attention is a cause of accident rates going up. This will only make it worse, until they can perfect the technology, as in how do they keep the auto pilot car from killing you when it breaks and you are taking a nap. 🙄
