The Trunkovs are modeled after the ZAZ-968 Zaporozhets, a car model from Soviet Ukraine, which means that there was a Soviet revolution in the cars history and by extension so existed the works of Car-le Marx and Vladimir Lemon.
Anyway, were all sick at the house and were just binging kids movies. Cars 2 is so weird. I thought the first 15 minutes were going to reveal to be some in universe movie the cars were watching. Then it just kept going...
My favorite Cars universe fan theory is the one that Jiblatner Mike and Fredrik Knudsen talked about one time, how all the cars are incredibly advanced robots, but once all the humans went extinct, they fell back on some strange base programming that makes them re-enact most of modern history from the ground up. Every single second of it, with a few variables to make the environment fit for cars. Which is why there was a Cars WW2, and a Cars soviet union, and a Cars pope, etc. Only beginning to create their own history after they ran out of instructions. It certainly has massive logic holes in it, but I think it's a fun one.
