And you are unfit to be making comments - I know quite well it's not self driving, the hype over "autopilot" is *way* overblown and I'm really glad I didn't waste money on "full self driving" which doesn't actually add much to autosteer.
That said, autosteer is a nice convenience most of the time and "Accelerate it to your liking and then let driver assist do it again" is not how it works. When it gets the speed limit wrong, it's simply unusable unless you like blocking traffic (or, I suppose, want to manually control speed while letting it steer, but personally, I prefer the reverse).
