We aren’t talking about the average human here.

On average you include sleep deprived people, driving way over the speed limit, at night, in bad weather, while drunk, and talking to someone. FSD is very likely situationally useful.

But you can know most of those adverse conditions don’t apply when you engage FSD on a given trip. As such the standard needs to be extremely high to avoid increased risks when you’re sober, wide awake, the conditions are good, and you have no need to speed.

The problem IMO is the transition period. A mostly safe system will make the driver feel at ease, but when an emergency occurs and the driver must take over, it's likely that they won't be paying full attention.

> you greatly overestimate humans

Tesla's FSD still goes full-throttle dumbfuck from time to time. Like, randomly deciding it wants to speed into an intersection despite the red light having done absolutely nothing. Or swerving because of glare that you can't see, and a Toyota Corolla could discern with its radars, but which hits the cameras and so fires up the orange cat it's simulating on its CPU.
