Today, there is at least one of the most advanced Neural Networks entering each car: A human being. If we could just implement the AI to add to this person and not replace it...

I will be amused, intrigued, and possibly a bit horrified if by the time FSD hits level 5, and they stick with the Neural Net of Neural Nets architecture if there isn't a rash of system induced variance in behavior as emergent phenomena take shape.
Imagined news: All Tesla's on I-95 engaged in creating patterns whereby all non-Teala traffic was bordered by a Tesla on each side. Almost like a game of Go, says expert. Researchers stumped.
Then again, that's imply you had an NN capable of retraining itself on the fly to some limited degree, which I assume no one sane would put into service... Hopefully this comment doesn't suffer a date of not aging well.
