    Yesterday was my first chance to play with autopilot for an extended period of time. On the whole the actual function worked pretty well.

    However, I had 2 hands on the wheel at all times, but still got a ton of "hold the wheel" warnings. It seemed as if a hand on the top 1/2 of the wheel didn't really count and on the bottom half I basically had to squeeze the wheel rather than just holding it to get it to register. Does anyone know what it's actually sensing? Is it pressure or a electric circuit touch type of thing? Is there some sort of preferred technique?

    I like the feature, but being chastised when I'm already holding the wheel firmly enough to yank it off of AP is annoying.

    Give it a little tug to the left or right once in a while. Squeezing it wont do anything. It's rotational resistance thats needed.

    Yep, it’s definitely not touch sensitive or squeeze sensitive. You need to put a little torque on the wheel. Enough that it can feel you, not so much that it thinks you want to drive and disengages autosteer altogether.

    I found that if I hold the wheel at the 9 o’clock position, and let my arm rest, it puts enough torque on it to keep the system from flagging me as needing to hold the wheel. If it does flag me, give the wheel a slight wiggle and the warning goes away.

    I used to do the wiggle, but now I find that I just maintain a slight turning pressure and I never get the warning.
