I don't understand its rules. Do the sentient cars feel pain? What part of them needs to "die" in order for them to die? The implication is that the voice actor needs to die, but even then the Paul Newman-voiced "Doc" is resurrected (along with Tom Magliozzi's "Rusty") in Cars 3 through the miracle of old voice outtakes and flashback sequences. It raises questions about sentience in a Blade Runner sort of way. It invites speculation that this is all a post-apocalyptic nightmare in which our "smart" cars have either outlasted, or outwitted, their primate creators. I wonder, too, about how they reproduce, as these films have always been clear that there are "children" in this universe. Or are they like child vampires: wizened monsters trapped in infant chassis? When I look at a sentient ambulance in this one's central "Flesh Fair" demolition-derby sequence and how its patient bay is built for a human-sized customer and not a car, well...it raises questions. And let's talk about the idea of a demolition derby in a film populated entirely by thinking, feeling cars. What would the human equivalent to this be? Thunderdome? It's worth a conversation, though it's not the conversation Cars 3 wants to have.See also:
Cars 3 — the latest kid-friendly Pixar film — is out today, but it will likely not address the fact that a car genocide happened in which Car Hitler exterminated 6 million Car Jews during Car World War II. It is very easy to prove that Car Hitler is real, using canonical Cars lore.
