So, Paul, are you saying that you have the same level of attention with
autopilot on as you would with no autopilot ? Not sure I follow what you
wrote.

Is this personal experience or conjecture?
I agree with the other poster. When in heavy traffic and on curves you will be
paying attention. At least I do! On the highway going straight I agree but
don’t find this to be hazardous. I have autopilot and sometimes it times out
because of this but the timer is around 30 seconds most of the time shorter if
there’s a lot or traffic or on roads with poor marking. Some roads it wont even
turn on. I don’t believe FSD is different. Maybe someone who’s used it can
share their experiences but here say is not useful information. My wife’s Lexus
has similar software and it works as well as the Tesla.

I don't have first hand experience using Tesla's autopilot. Assuming you
are paying attention, then what is it like when autopilot fails and you
have to take control ? If you are paying attention, it seems to me that
it might take a tenth second or so to react. I'll guess that in nearly
all cases, that would be enough time to handle the car easily and
safely.
However, I'll further conjecture that most drivers aren't really paying
close attention when on autopilot. Even if they have the hands on the
wheel, how much time would they take to react ? One-half second ? More ?
That makes a huge difference in safety.
This is my real issue with AutoPilot / FSD Beta - really, any driver
assist system that does most of the driving. For safety a human being
has to be monitoring the situation. As a point of comparison, let's
say we set up a test where you and a friend have your hands extended.
Their hand is over yours. This is the slapping game. The goal is for
them to be able to slap your hand before you can pull it away. If you
play this game and slaps come within, say, 10 seconds you will be
prepared. You might not always win the game but you are looking
intently and you're ready. If they so much as move their hand you
start to tense up. Reaction time is very rapid. Now, extend that game
such that the slap might come within a 1 minute window. Your reaction
time is likely a bit less because you get a little bored and focus
fatigued. Now extend the time to 30 minutes. If the slap comes at the
21 minute mark you have probably long spaced out and aren't actively
paying attention any longer. Let's add a TV which is on and playing a
movie in the background. Almost certainly after 21 minutes you've been
watching the movie instead of playing "the game." Semi-autonomous
driving is like that. You get complacent when things are going well.
The reaction time gets worse and worse the longer a human is not
really required. Then, when you are required there is no time for the
human brain to get back in the game and assess the situation before it
is catastrophic. It seems to me that everyone likes to minimize this
aspect of the discussion. But, it's the most important part I'd say.
FSD Beta is dangerous because it is not yet fully able to handle all
situations but it is very tough to convince the human brain to pay
attention to minute details when nothing exciting is happening. This
is also why guards work in shifts. If your job is to "look into the
woods and find the bad guys that might be here in 5 minutes or 5 days"
you WILL get bored.
