Or did you mean strictly in operation?

This seems like an odd take. Don't existing self-driving cars already have rather a lot of world-model? It's not like they're just hooking the driving apparatus to the output of an LLM or something.

(Of course there is also scope for debate about how much world model today's LLMs have; it seems like it's more than none even though it has to be built out of token-shuffling parts. But that's not relevant here.)
