> This needs far more discussion. I just don't buy it. I don't believe that you can have a car engaged in auto-drive mode and remain attentive. I think our psychology won't allow it. Does anyone know of psychology studies that measure human reaction time and skill when sometime like autopilot is engaged most of the time? I remember taking part in a similar study at Georgia Tech that involved firing at a target using a joystick. It was also simultaneously a contest because only the top scorer would get prize money. The study was conducted in two parts. In the 1st phase, the system had autotargeting engaged. All subjects had to do was press a button when the reticle was on the target in order to score. In the 2nd phase, which was a surprise, autotargetting was turned off. I won the contest and my score was miles ahead of anyone. I can't fully confirm it but I feel this happened because I was still actively aiming for the target even when autotargetting was active. |

Yes. That's been much studied in the aviation community.[1] NASA has the Multi-Attribute Test Battery to explicitly study this.[2] It runs on Windows with a joystick, and is available from NASA. The person being tested has several tasks, one of which is simply to keep a marker on target with the joystick as the marker drifts. This simulates the most basic flying task - flying straight and level. This task can be put on "autopilot", and when the marker drifts, the "autopilot" will simulate moving the joystick to correct the position.
But sometimes the "autopilot" fails, and the marker starts drifting. The person being tested is supposed to notice this and take over. How long that takes is measured. That's exactly the situation which applies with Tesla's "autopilot".
There are many studies using MATB. See the references. This is well explored territory in aviation.
