> How is it that humans can learn to drive a car in about 20 hours of practice with very little supervision, while fully autonomous driving still eludes our best AI systems trained with thousands of hours of data from human drivers?

Wow, are these so-called ai scientists really that daft?

Sure on paper we drive 20-40 hours "practicing" then hit the roads, but we've been back-seat driving and driving via video games or TV since the day we're born.

While a 2-year old doesn't know the intricacies of driving my 3-year old can definitely yell hey dad the lights red slow down.

Full-immersive life experience. Perhaps ai's need to be put into a real-world "birth" simulation (perhaps we already are this experiment) to learn as they grow.

The problem I see is the narrowness, if you're training on a narrow subset then you're gonna get narrow results. I don't know the best way of doing it but you need to start thinking of an ai's "brain" like that of a child's and how it absorbs things - the human brain is remarkable sure, but I don't doubt it's duplicatable in silicon.
