"Hold Steering Wheel" - What's the purpose?

[Torpedo Ted]

Message seems to come randomly. Sometimes it appears although car sees lines well, on the other hand, sometimes car plays ping pong between lines and still no message.

That's my impression as well. It makes no sense to nag me when the car is doing perfectly fine. But when it's clear that the car has major problems reading the road and drives worse than a drunk, there's no warnings at all.

My hold steering wheel message can be grouped in 3 categories right now:
-Curve in the road
-Large truck in a neighboring lane too close to the white line
-Undetermined

It would also keep idiots from putting a sack of cement in the front seat and going in the back seat.

Ive noticed that I get the message more often if I'm cruising at a higher speed. 75mph seems to trigger more alerts vs 65mph.

Almost any time the car asks me to hold the wheel, it's going around a curve. There have been times when I was confused as to why the car needed help, on a straight road with good markings, but this seems to be happening less frequently. There have also been times that I've gone around a curve which I was pretty sure would trigger the warning, but the car handled just fine without any request to hold the wheel. The autopilot also seems to be handling curves somewhat better than it used to. Overall, I've been very happy with the autopilot performance and while I'm not 100% certain of what triggers the warning to hold the wheel, I am 100% certain that it's not any sort of regularly timed nag feature.
