Consider the difference between supervision and intervention.
All production Teslas need human supervision, this is enforced with driver monitoring systems as a safety procedure. But the current versions of FSD, released in the last few months, can often navigate through most or all driving situations without human intervention. So the computer will make sure you are paying attention, but will in most cases execute the drive perfectly without making mistakes that require the human to take over.

There’s plenty of videos on YouTube check some of them out :)
