You may want to look into Alpha Zero. It learned to play chess at superhuman levels in just hours of play. The only human assistance were the rules of the game.
That wasn’t human instruction but it was arguably better since human instructions are ambiguous and imperfect. No chess grandmaster could instruct a chess engine to play better than the state of the art. Completing a task from first principles is much more powerful.
And once have an AI engine that, given just the instructions on how to drive a car and a list of road rules, can operate one perfectly, I'd agree we're a huge step closer to an AGI (if it can also learn how to do all the other things most humans can just given similar inputs, then sure, it would qualify unreservedly).
Sure, and at that point we can shift the goalposts to some other task since driving (like chess) will seem easy in retrospect.
Put another way, what would a system which has taught itself to drive tell us about general intelligence that we didn’t already know? Because as of now it seems like the pattern is
Computers could never do X
Computers can’t do X
Computers can’t do X very well
Computers can’t do X well in some cases
X wasn’t really a test of AGI because it’s just <algorithm to do X>
Well, let’s think about it from the opposite direction.
Say we built a general system without teaching it anything about driving. We discover that it can drive at a human level. Would we then be surprised if we discover that it cannot solve any other complex tasks at a human level?
I say yes, we would be surprised. I think that driving well requires enough general intelligence and that any system that solves it will be able to also, say, pass a high school algebra class or cook a meal in an unfamiliar kitchen. There can be no further goalpost moving at that point.
