This seems to be simultaneously discounting AI (ChatGPT should have put to rest the idea that "it's all replication and repetition" by now, no?[1]) and wildly overestimating median human ability.

In point of fact the human brain is absolutely terrible at driving. To the extent that without all the non-AI safety features implement in modern automobiles and street environments, driving would be more than a full order of magnitude more deadly.

The safety bar[2] for autonomous driving is really, really low. And, yes, existing systems are crossing that bar as we speak. Even Teslas.

[1] Or at least widely broadened our intuition about what can be accomplished with "mere" repetition and replication.

[2] It's true though, that the practical bar is probably higher. We saw just last week that a routine accident that happens dozens of times every day becomes a giant front page freakout when there's a computer involved.
