!!What do these vehichles run on, again?
* Why would a world populated entirely by motor vehicles (which have been established in-universe to run on gasoline) grow crops?
** Biofuel? For the cows to eat? Which produce gasoline milk?
** Synthetic gasoline and jet fuel are the most likely answers.
** Biofuel is even briefly discussed in the movie (some of the planes were talking about fuel made of corn). Now where does the fertilizer come from?
*** Petrochemicals. ...How sustainable.
*** This is probably the point where one says [[MST3KMantra "Hey, it's just a cartoon..."]]
** An explanation is that their ''engines'' need oil and gasoline to run, while the more "organic" (?) parts of their insides needs food. How would any of that work? Let's go with that ''Cars'' and ''Planes'' take place on some alien planet.
!!Ancient planes?
* Mexico in the movie is presented as Teotihuacan with runways, and the pyramids being hangers. So... what would an ancient Aztec airplane look like?
** Who says they had airplanes? The Nazca lines don't make any sense on the surface either.
!!Somethin' outta place?
* Where in all of Shanghai did Dusty find, of all things, a ''mariachi band?!''
** Perhaps the scene was originally going to take place in Mexico, which was the next stop.
** They might be El Chupacabra's fans.
!!Skip's Armament
* Does Skipper still have his armament? Given the speeds a corsair can hit having him on their tail could have ended badly for the antagonists if Skipper knew about the murder attempt.
** Unlikely, given that most modern warbirds have their guns removed and the gunports filled in and smoothed over, for hopefully obvious reasons. Given Skipper's wartime experiences, I don't think he'd be too attached to them. Besides, if he wanted to use them, he'd still need ammo, and it would raise a few eyebrows to see military grade munitions being delivered to a nearby hangar.
