You are assuming Tesla actually needs all that data to train a competing model, you're also ignoring all of the other training a human has before ever starting to drive. It's not so clear who is more efficient, not at all.

I think a better way to compare is thorough the lense of energy, a human brain runs on about 40w of energy, Tesla's models are trained on MW scale computers, how do they compare in terms of total energy spent to achieve certain performance?
