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.
