Caveat: I'm a huge Tesla fan, and I have owned a P85D for 3 years now and love it. I also love AutoPilot and use it all the time. I think Tesla provides ample warning about driver responsibility when you enable the feature and I can't stand when people blame the car for their own mistakes.
With that being said, I find that "holding the steering wheel" is a horrible proxy for "paying attention", yet when Tesla posts information about crashes while on AutoPilot, they really seem to focus on how much the person was or wasn't holding the steering wheel. I just find that useless and misleading.
First of all, it is trivial to hold the steering wheel while not paying any attention. You could even be accidentally asleep and holding on to the steering wheel.
Secondly, at least for me, the most comfortable position for me to hold on to the steering wheel when I'm not driving is a loose bottom grip with one hand. But for taking over control from AP I prefer to use the standard "10 and 2" grips. When AP forces me to passively hold on to my steering wheel, in effect it just puts me at a slower response time for the grip I use when taking over. In other words, in my case, I'm confident that I'd be better off NOT holding the steering wheel, and simply being ready to take over.
Finally, Tesla also likes to talk about how many times people were visually and audibly alerted to put their hands on the wheel. Again, I think this is used to show that the driver wasn't paying attention. However, as I said above, in my case I'm more comfortable watching the road with my hands *off* the wheel, ready to grab at 10 and 2. So I get alerted to hold the wheel and I jiggle it and resume what I'm comfortable with. Most importantly, I almost *never* see the "hold the wheel" indicators... because I'm watching the road!
Basically, as a veteran AutoPilot user, I watch the road very carefully and I'm ready to take over the wheel in the 10-and-2 hand positions very quickly and when I do I can make significant adjustments to the steering. I think I'm an extremely safe and competent AutoPilot user for these reasons.
However, if I ever get into an accident, the Tesla report will go something like: "Driver had his hands off of the steering wheel for 45 of the 60 seconds before the accident. Driver receive 6 visual and 4 audible alerts to hold the steering wheel in the 5 minutes prior to the accident." I think that will completely misrepresent the level of care I take when using AP.
