Earlier quoted context omitted.
What other vehicle will change lanes by itself, and take on/off ramps through interchanges to take you where your navigation is routed, without you touching a single thing?
You have to keep touching the wheel or it will disengage. It sounds like you’ve never used it.
What I mean is, you are not providing input to the wheel, or pedals, or turn signal or driving the car in any way. You're just letting it know you have not fallen asleep.
And, yes, thanks for asking, I have used it.
