So far, they are not.
I haven't seen good stats on Tesla (they are less transparent than Waymo), but it would shock me if they weren't also at least slightly safer than the average human driver. Human drivers are really bad at driving.
But even if Tesla isn't safer, taken as a whole, the self driving industry as it currently exists still probably is, purely because it's mostly Waymo, and Waymo is dramatically safer.
I think humans will eventually fall out of practice of driving when they use SDVs for most travel. And then every once in a while they'll take their ol' 2026 classic car from highschool out for a spin and find they have forgotten how to drive!
