FSD does use the internal camera to enforce eyes on the road hands on the wheel. It’s actually worse for road-trips on the highway than plain autopilot for this reason, aside from the fact that FSD will automatically pass and change lanes.
Acktshually, negging would be a tad bit more subtle than that. It is a form of backhanded compliment.
I imagine a negging Tesla car would say something like "it's so cool to see a person who has so little to lose they don't care whether they live or die" when you take your eyes off road and/or hands off wheel.
I find the time varies, and that the amount of attentiveness required is much lower than that for FSD. FSD will ding you very quickly if you have a device in your hand, especially compared to plain autopilot.
My car came with an internal camera that didn’t have IR lights, which made FSD completely unusable at night time (they put in a new one under warranty).
I only subscribe FSD every few months for long trips, but I have a 1400 mile road trip planned this weekend and I will be using plain autopilot.
