Assuming positive intent here, I'm not sure how you reason that a fusion system might be less performant than a single model? My whole point is that a single system is not sufficiently safe to do what we're trying to do. The point of FSD isn't just to navigate without hitting stuff. The point is to do it with ~99.999% accuracy, ~99.999% of the time while flying down the road at 80 MPH. Humans are _terrible_ at this, just check the deaths due to automobile accidents each year. We have some pretty amazing stereoscopic vision. But I don't like trusting my safety to another human, and I sure won't trust it to a machine whose vision isn't as good as mine. For me to trust a machine, it needs to be an order of magnitude better than myself.
