If your'e a Tesla owner that is unhappy with the steering wheel nag, I have a suggestion for you.
I also just got the updated software, and I haven't noticed a change in the nag's behavior. I think that means that my steering wheel input mechanism is what Tesla is looking for, as evidence that I'm present.
The key is to realize that the car is looking for / sensing torque or twist on the wheel. Not so much that you break out of AP control, but enough that the car knows you're there. To apply that torque continuously, hang your hand from the left or right cross bar on the steering wheel. My arm is long enough that my left elbow rests on the arm rest on the door, and the left hand has 1 finger hooked over the cross bar on the wheel. I routinely drive an hour + drive between houses with nary a nag, and that included yesterday on the new software.
If you're resting your hands in your lap or you are gripping the wheel, then you aren't providing resistance to the wheel twisting (such as on a straight away where the AP isn't trying to turn the wheel). Your torque / resistance on the wheel isn't consistent enough for what's being tested.
So hang your hand from either side of the wheel - your hand + arm is lighter than the weight / torque needed to break out of AP, and will provide continuous assurance to the car that you're there.
