I'm not sure how you take that from the original article. My 4 year old would drive that course in an automatic car, if only he could reach the pedals. Heck, he's done harder things at Lego land.

I wouldn't let him loose on the road though.

I think, at the very least, the guardrails would have to deterministic, ideally with super human senses, for people to accept self driving cars on the road.

Your four year old has billions of years of learning embedded in his weights/architecture for generalized motor control :)

Maybe 4 year olds already have the brain power to learn to drive if they so desired.

Nope, no "deterministic guardrails" for you. The domain is simply far too broad and unstructured to allow for that.

Unless you mean "a typical AI with all the computation constrained sufficiently to always unfold the same exact way, given the same input". In practice, that just kicks the can to "given the same input" street.

The noise in the system is going to come from the input plane. Which is, I remind you, facing the real world. It's full of noise.
