> Asking drivers to keep their eyes on the road and hands on the wheel while not steering guarantees that their attention will wander, because their brain isn’t getting enough stimulus to keep focused on the task.

Completely agree! When I'm driving her Tesla (no RSI issues here) I much prefer to use the adaptive cruise (which is really nice) and do my own steering for exactly the reason you cite. I have to pay attention anyway and steering keeps me from getting bored. Plus I do things like, you know, pass and keep myself from getting into bad situations that are many seconds ahead.

I only use AP to demonstrate it as a party trick to folks who have not seen it before. I half agree with the "use crowd sourcing to get AP training sets" but I completely disagree with how the thing is currently marketed -- even if (as you say) the legalese tries to cover Tesla.

Don't get me wrong: Her Model S is a spectacular car. I love it. But AP is somewhere between a party trick and a death trap unless, like my wife, you have serious problems holding the wheel for hours and are therefore happy to sit there and "supervise" what is a bad expressway autopilot.
