> Almost every study on human behavior contradicts this. When you have no load, your monitoring and responsiveness gets poorer, not better. (Now, you can certainly go to the other extreme and get overloaded, with the same effect)
With both a plane and a car you still have some load; you are supposed to be monitoring the performance of the systems.
I perceive myself to be safer when I have autopilot enabled on a Cirrus. My thinking goes from having to manipulate the controls to monitoring the performance of the aircraft.
I could be derelict in my duties at ignore the plane and play a game on my iPhone.
I perceive that experience to be very similar to when I engage Autopilot on my Tesla.
I go from having to manipulate the control to monitoring the performance of the car. With over 110k miles on my Tesla I really do feel with autopilot.
