Ok but don't you have to weigh that against the potential of avoiding accidents by reacting quicker then you as a human can?
I have defiantly seen cases where FSD Beta stopped and the driver didn't understand instantly understand why.
Or simpler cases where the car follows a lane while the driver wasn't paying attention (adjusting the radio or whatever). Those can easily lead to an accident but are unlikely to if you are in FSD.
How do you make that calculation?
