I'm guessing Elon's experience with any "FSD" version goes this way:
1) He gets it before anyone else. He drives it on limited routes in the LA or Brownsville areas that engineers know he will drive. It works pretty good in those 30 minutes (he's a busy guy, let's not pretend he ever drives it more than that). He tweets that it's awesome.
2) It goes to "FSD" beta testers. They use it in actual, hard traffic and city streets, not just highway entrances. They post YouTube videos. It's not great. Elon sees this and adjusts his opinion and resets his expectations for the next version (but usually doesn't tweet that)
3) Repeat #1, where now his drive is better than the YouTube videos of the previous version, so it must be amazing, because he forgot he already said the previous version was amazing before he learned that it was not.
