You are risking your life and the lives of others in return for convenience.

Why is this a benefit? In this video [1] you only have two seconds to make a correction.

That is concerning given what we know about AP's behavior.
The behavior demonstrated here was new as of March 2018, later disappeared, and then reappeared again in an AP update in 2019 [2]. This issue was also demonstrated to appear at the location of a Model X crash that resulted in a fatality [3].
Then there are the two left-turning white tractor-trailer deaths in Florida, seemingly identical conditions on divided roads, spaced 3 years apart [4] [5].
You could say, "well I don't have conditions like those where I commute", but then, you don't know where the next screw-up will be.
EDIT: Here is another case, just happened two days ago [7], a Model X on autopilot unexpectedly veered right at highway speed, crashing into a truck.
Also note, there is no proof that AP is safer. NHTSA's "40% safer" claim was debunked when they were forced to release data as a result of a lawsuit [6].
> In fact I personally think it's quite analogous to how airplane autopilot actually functions
Airplane pilots have minutes to react to autopilot malfunctions. In a car you may have only 1 or 2 seconds.
