What the hell is going on with Cars? There are no people – yet there are sidewalks. I never saw the first film so maybe I’m missing something but I’ve had a hard time wrapping my brain around the universe portrayed in it. Maybe I’m overanalyzing it, punching a dead horse, and whatever other cliché you can insert here but it’s wrong – on many levels. Finally I’ve concocted a theorem about Cars’ civilization:
A long time ago motor vehicles gained consciousness somehow and overtook humanity. Subdued, in a Matrix-like fashion, humans are now the fuel for the cars (one character mentions “fossil fuels” at some point). Very much like Motel Hell the humans are harvested, possibly living in a computer generated reality, and used as fuel. Why else would there be sidewalks in a civilization entirely populated by cars?
