It's a horrible comparison. Why do people keep making it? This isn't Lyft vs Uber. A better comparison to Tesla FSD would be blue cruise, super cruise, drive pilot, god's eye, and every other consumer level 2 ADAS.
To me this metric shows that their cars are very high performing, and for most drivers they're probably the fastest accelerating cars they've ever driven. Tesla should probably default them to 'chill' mode and provide a warning about how fast the car is when you switch out of that mode.
For instance the model y had a fatality rate of 10.6 per billion vehicle miles 4x the average.
Its also seems unreasonable to suppose that they are poorly suited to survive a crash as this doesn't seem to be indicated.
A more logical conclusion is that a box with a giant flashing distracting tablet in the center which lies and says it can drive itself gets crashed more because people are functionally incapable of going from passenger to driver at random intervals with no notice.
I wonder if segregating bad drivers into a separate population affects those fatality statistics.
