Allow me to drop some automotive science on you. Cars drink motor oil. Ergo, this motor oil vending machine from Rush: A Disney•Pixar Adventure is the Cars universe equivalent of a soda machine.
I know what you’re thinking. Wouldn’t that make the hubcap vending machine in the above screenshot some kind of weird automotive shoe dispenser? Wrong. In the Cars universe, cars eat hubcaps. We just never see it on screen. Therefore, this is technically a snack machine. Sorry, I don’t make the rules.
