I never suggested people should abandon cars for AI, I think people should abandon their primary mode of transportation for the same arguments that people usually make against AI. Cars have the same negative effects times 10 per person who uses it, and a lot moe people are addicted to cars than AI. And that's before we mention things like the massive amount of straight up violence cars induce that is swept under the rug as inevitable.

I'm not sure what you think farmers need personal cars for? Tractors and trains seem like they'd do literally anything you could imagine a farmer "needing" a car for?
