You’re not wrong, but arguably that doesn’t invalidate the point, they do drive better than humans because they’re so much better at judging their own limitations.
If human drivers refused to enter dangerous intersections, stopped every time things started yup look dangerous, and handed off to a specialist to handle problems, driving might not produce the mountain of corpses it does today.
That said, you’re of course correct that they still have a long way to go in technical driving ability and handling of adverse conditions, but it’s interesting to consider that simple policy effectively enforced is enough to cancel out all the advantages that human drivers currently still have.
If you select a number “fairly” (ie every number equally likely, not skewed towards smaller numbers) and your scale goes to infinity, I’m pretty sure the number you get out will be infinitely long, almost always (sure, you could get the number 10, but infinity is… infinite, so any number that gets picked will tend to be beyond anything we ever experience or know how to write down)
To put it another way, using your scheme, we’d only ever need 1 random number ever, it’d just keep printing forever and we could cut up chunks of it whenever we needed some random and it would just keep printing on and on.
