Waymo is operating and doing passenger miles commercially with no one behind the wheel. Tesla hasn't yet done that even for the controlled Vegas loop they said they would do it in. Waymo still has remote operators who can handle unusual situations but they handle multiple cars and only the car itself responds to sudden events. They are operating at level 4.
Tesla still has one local operator per car who has to be able to have twitch reactions at all times.
Competitors like Honda and Mercedes also let you take your hands off the wheel and eyes off the road in certain areas (level 3), which Tesla hasn't yet achieved.
Tesla FSD is still a level 2 system.
