Tesla says “ we count any crash in which Autopilot was deactivated within 5 seconds before impact, and we count all crashes in which the incident alert indicated an airbag or other active restraint deployed” https://www.tesla.com/VehicleSafetyReport

But even without that, there are no allegations of such FSD beta related fatal or incapacitating incidents, who would say it even if the beta put the human in harm’s way 10, 15 seconds earlier. The black box in the car includes both the dash cam camera and whether auto steer is activated, so any fatal crash would still leave such evidence of Beta being active.
