As can be witnessed in loads of videos on YouTube, the current FSD betas still pretty much require full attention (I would say even more attention than driving youself because you have to watch the environment AND the behaviour of Autopilot). And these demos are on American roads which are among the easiest to drive in the world (generally very wide, lots of traffic lights, large intersections, etc.).
Bad weather conditons (which are a thing outside of southern California) are even more problematic. So while the tech might or might not be more advanced than what other car companies have in their labs, reliably its still pretty much an improved cruise control and in that regard not that far ahead of the competition (all premium brands have that in one way or the other).
