Tesla collected 780M miles of driving till 2016

A human learning to drive for 16h/day at an average speed of 30mph for 18years would have a data set of ~3M miles.

So we can say humans are at least 1000 times more sample efficient than whatever Tesla and any other autonomous driving companies are doing.

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?

Probably not, because a 16 y.o. human has 16 years of interactive navigation pretraining in a real world environment in real time before learning to drive. So it depends on how you include this pretraining.

And it also depends on the accuracy of the model as a function of the size of the dataset. Let's say Tesla is 80% (random number) accurate while driving after training on 780M miles, a human is 75% accurate after 3M miles, and if you train the Tesla model on 3M miles instead of 780M it's 75% accurate, on these metrics alone Tesla would be as efficient as a human.

No comparison is perfect but we can't ignore that during the first years of our lives we train to understand the world while not being very efficient to perform tasks.
