I don't think that's quite right. I believe that humans are essentially born as blank neural networks; it's the structure, and the graph of connections between brain structures and sensory inputs, that is effectively primed for learning certain tasks that we find to be intuitive.

Perhaps born is the wrong word. That freshly-born baby did have nine months of gestation during which it's undoubtedly been exploring how to move about and sense its very limited environment.

I’ve said this before, but I think that a lack of physical modeling might be the key barrier for AV technology. Human drivers have a mental model of physics that they’ve honed for 17-18 hours a day since they were born.

Vehicle dynamics is a fairly accurate science these days (50/50 for the tires)

Sure, but to be clear, I meant physical modeling which includes real-time modeling of all salient objects and surfaces in the immediate and foreseeable environment. I mean going as far as creating a physical model for deer, their range of behavior and speed, weight distribution, predictive modeling for subsequent behavior, etc...

Don't sell biology short like that. Human driver are born with a mental model of physics that's been honed 24 hours a day since before they were diatoms.

We're not even a dirty blank slate.

There are a zillion skills, aptitudes, and personality traits more or less hardcoded in a newborn.

Which is why there is such a thing as "human nature" that is meaningful to talk about.

Eh, I've seen my baby sucking on its thumb, and then the baby jerks and the thumb goes away, baby cries, somehow the wild flailing gets the thumb back to the mouth. Baby happy again, sucking on its own thumb.

I agree that we are not born a blank slate, but at the same time, there's a lot of knowledge missing on a newborn baby.

Side note, is "AV" to mean "autonomous vehicles" (assumed from context) a common usage? I've only ever heard it mean "audio/visual".

> autonomous vehicles

...oh that makes so much more sense! -.-
