History Fridge / Cars

* In Cars 2, the discussion about dinosaurs and fossil fuels is brought up, chiefly that fossil fuels such as gasoline are derived from dead dinosaurs in a manner analogous if not identical to fossil fuels for us humans. So think about that for a second: gasoline serves as the main sustenance for cars in this universe, and gasoline, a fossil fuel, is derived from dead dinosaurs. But in the Cars universe, everything is a car or at least some sort of vehicle, thus dinosaurs can be assumed to be cars as well. This means that when a car in Cars drinks gasoline, they are in fact eating their long dead ancestors. [[IncrediblyLamePun Charlton Heston]] [[Film/SoylentGreen was right]].

* When we see Stephenson the bullet train take Mater, Finn [=McMissile=], and Holly Shiftwell from Paris to Italy so they can infiltrate the Lemons' casino, pay very close attention to Stephenson's caboose (it only appears for a split-second) after emerging from the tunnel leading to Italy.
** Most bullet trains have locomotives on either end, so the inactive end will serve as the "caboose" to the one that's pulling the train. In some US commuter trains (such as Chicago's Metra), there are two motorized ends. One is an actual locomotive, the other is disguised as a caboose (there are red-and-white safety stripes painted onto the end).

* Trev Diesel doing a long honk when Lightning sped up may seem like he was also speeding up at first glance, until one realizes that a long honk on a train is actually a warning to clear the tracks immediately when the train is approaching. Trev wasn't increasing his speed, he was telling McQueen to slow down.

* Mater being interested in the French market not only because there's interesting stuff, but since it's his job to tow stuff around he'd probably like to see all the stuff and learn about it to increase his knowledge...if you call it that.
* Also, in the second film, Mater takes out three or four cars that try to jump Lightning by himself. Of course -- he's used to being around broken-down cars, so he knows their weak spots.
* During the first race of the film, [[https://static.tvtropes.org/pmwiki/pub/images/red-ones-go-faster2_1730.jpg as seen in this still frame here]], the entire audience in the background is composed of either red or blue spots, and no obvious green spots. This means that every car there is supporting either [=McQueen=] (the upcoming rookie) or King (the seasoned veteran in his swan season), and not as many obvious supporters of Chick. It certainly makes a bit more obvious why [[GreenEyedMonster Chick is so jealous]].

* When Sally goes to court, she cracks a joke about [[DidYouGetANewHaircut Doc doing something with his side view mirrors]]. Which is the same idea as asking a balding man if he's doing something with his hair, since Doc only has one mirror. Hmm, that's weird, most of the cars in the movie have both side view mirrors. The most prominent ones that don't are Lightning and other...[[{{Foreshadowing}} race cars]]...

** Except in ''WesternAnimation/Cars3'', it's shown Radiator Springs does get snow.
* While you can of course chalk it up to PlotArmor, Lightning making it through Thunder Hollow's Crazy 8 demolition derby without a scratch makes sense when you consider that Lightning once expertly navigated through a huge pileup Chick's caused way back in the first film.
** Made all the more effective that Doc Hudson taught him how to properly drive on dirt as well.
* Tony Trihull looks out of place being a modern warship among older lemon cars, unless you are familiar with the teething problems the Littoral Combat Ships had. He's a lemon as well.

** If fossil fuels are going to be used up (if they are like ours- which is implied) so unless they come up with perfect alternatives to fossil fuels, eventually everyone in that world will starve to death.

* In one of the deleted scenes for this movie, while Lightning [=McQueen=] is lost, he drives into an area filled with just the outer bodies of cars, abandoned in the middle on nowhere, obviously long enough for the foliage to start growing through them. He, of course, gets freaked out, and you realize exactly how creepy it is when you think of the human equivalent of that...
* Speaking of Cars, where the hell are the humans? The cars are obviously developed to fit humans in them seeing as they have seats and rear view mirrors. What did they do to the humans?
** We never see inside ''any'' of the cars. Their windows are always opaque and grey. Convertible characters are always seen with their roofs up. The only time we see seats inside a car is (I've only seen ''Cars 2'' once, so I could be wrong) the car in Paris with her eyes in her headlights. All of her windows (and windshield) are transparent, and (I think) there are seats inside. (Likely a parody of Chevron cars.)

** Also, it's not just cars anymore: ''Cars 2'' shows us a talking plane, and Disney is has an entire ''WesternAnimation/{{Planes}}'' spin-off. By extension, does that mean that military vehicles are sentient? If so, and at one point they were accompanied by humans, what would they do if confronted with violence that they didn't want to commit? Or, even worse, what if they ''did'' want to commit violence? Could they have grown hateful in a bigoted environment?

** An alternate theory - there are also references to "birth" and to family relations (mothers, brothers, sisters, uncles, etc.) in-universe, so that implies that vehicles of this world may in fact be "born" in some fashion. Perhaps the role of factories, then, is to "modify" or "standardize" the resulting offspring. Imagine being an unaltered "natural" child in this world, especially if your mother was of one make/model and your father was another. Yikes. If it ain't Literature/BraveNewWorld, it's Gattaca! The fine folks at Pixar/Disney have been rather sketchy on the "birds and bees" of Cars, probably for this reason.

* A BlinkAndYouMissIt gag in the first movie advertises a restaurant with "topless waitresses" which apparently means convertibles with their roofs open. That's what all the ride vehicles for [[Ride/DisneyThemeParks Radiator Springs Racers]] are.

* The cliffs surrounding Radiator Springs all look like either 50's style cars, or muscle cars stuck in the ground.

*** There's a bit in ''Planes'' where we see the New York skyline... and there's no Twin Towers. Meaning ''there was a Car 9/11''. '''''And the plane that hit them would've been sentient'''''.
