My favorite part of this thread is how it illustrates why the technology is so awesome: nobody is forced to use it.
Everyone has their own comfort level behind the wheel, and the system provides as much assistance as we want or need. I think autopilot has some advantages with reaction time, but it's a mixed blessing because the system is virtually incapable of anticipating people's reactions. I'm absolutely certain it can brake faster for slowing or stopping traffic than a human driver, or even countersteer when an accident is imminent. Whether or not that outweighs the system's inability to see problems arise further out is probably dependent on the drivers level of alertness.
I've driven about 24,000 miles in the last year, 90% of which have been on autopilot. I've gotten to know the system well, and fully understand why some are afraid to use it.
It is not only comfort level. Roads and driving conditions matter. When highways are open and there no triggers for things such as fantom braking and following "wrong lane", or when there's stop-n-go traffic, autopilot helps. In my daily driving I am mostly in between.
Then some people are OK to follow the slow lane on AP and some people like to be efficient.
Some people are too afraid to give up control, some don't realize dangers, and some in between, but all of them call themselves realists.
Some people are OK with autopark taking 5x the time of self park and risk scratches.
I again am thankful to those who use autopilot a lot and help train it.
Also, as I mentioned in another response, when I got my car, Autopilot did not do any fantom braking and didn't abort lane changes I triggered. It was more useful for my commute pattern. It got worse for my practical purposes.
From your comment it was not clear if you think $4-7K for FSD worth it or not.
