The FSD Beta uses the in-cabin camera's to do eye tracking and all the other attention stuff.
It may have been true at the time, but now Tesla uses the interior camera to make sure you are paying attention to the road.
If you don’t want to use the FSD beta, you don’t have to activate the camera, or you can put tape over it. With either of these actions the user can opt out but will not have the ability to use the beta.
