The fundamental problem is that Tesla's Autopilot is defective. It has repeatedly steered people into highway barriers, and sometimes has no clue which lane it's in or where it's going. See the opening of this video:
https://www.youtube.com/watch?v=sMvdI8nSAJEAn Apple employee was killed by his Tesla, which always veered into a highway barrier after an OTA update (he was distracted one day and didn't prevent the crash, died as a result).[0] The video above also involves the results of an OTA update.
There are more reports of dangerous Autopilot behavior than any other brand's cruise control that I'm aware of.
The problem here isn't neglectful driving, it's that you may be driving in a straight line on a highway for half an hour, distracted and "lulled" by the monotony and predictability of the road, and in a split second your car veers off and tries to kill you because it no longer knows where the lane is.
Now drivers need to not only pay attention to the road and over cars, but also be ready to react instantly with zero warning if the car does something unexpected and dangerous.
