Mater is a closeted homosexual.Jossed in the sequel. Why do people keep guessing this for at least one character in EVERY show?
Satan made the carsThere, problem solved. You might be wondering why it was Satan and not God; its because mankind supposedly was made in Yahweh's image or some bullshit like that, so God cannot possibly be behind the creation of sapient, non-anthropomorphic cars. By contrast, Satan/Lucifer is described as a draconic light/air angel in the Bible that vomits water. It may not seem very car-like, but that's just because he has more imagination.
Alternatively, Cars takes place after Maximum Overdrive.Sentient cars, machines with dangerous and even homicidal tendencies? This is what happened after the humans were forced into hiding!
Cars and the Burnout games take place in the same universeBoth include a world fully designed to accommodate humans while distinctly lacking them, and feature self-piloting cars. Burnout would occur somewhere in the brutal past of Cars or in the bleak future, when society has dissolved and all the cars have turned feral, possibly due to The Virus.
The Cars world is not Earth, but a long-lost colony of Velocitron in the distant future of Transformers Cybertron.The ancestors of the characters were Velocitronians who visited Earth, which is why their descendants have Earth car forms; they were cut off from other alternatives. Rather than return to Velocitron, they decided to forge a new world of roads to challenge their racing skills. To honor the humans' part in stopping the Unicron Singularity, they named one of the first major roads after an Earth locale, Route 66. Soon after, a remaining group of aggressive Decepticons attacked and hit the planet with a version of the transformation lock virus from Beast Wars. The Decepticons were defeated, but the Cars Worlders were trapped in vehicular form; even the data used in reproduction was corrupted. Eventually, the Cars Worlders descendants lost the capacity for transforming and evolved into the body styles of the film. The only remnant of the faded memories of Velocitron is a love for racing; those skilled at it are treated like we treat pro athletes.
The Cars universe is our world after everything was automated, cars were intentionally given artificial personalities and put on a grid, and everyone died of something stupid (poison or radiation) that doesn't cause property damage.The reason the cars have opaque windshields is because nobody ever drove once the cars were put on the computer-control grid. People could watch movies on the inside during long trips and give the outside more "personality". The cars are more squishy because they are made of super tear-resistant fabric over warping frames (unlikely, looking at Mater), or are Nerf cars, both of which are real concept designs (the former of which was available on the market a couple of years ago from BMW). Something happened to humans at least 50 years ago that didn't wipe out electronics. The reason that cars correspond roughly to our current cars is that the classic-style cars were only made for collectors, and the more modern-looking cars were mass-produced. The cars can still fuel up and everything because the pumps are fully automated and/or they use some sort of hydrogen fuel cell that we have yet to invent, and the tractors were built as non-methane producing replacements for cows after artificial meat became popular.
The Cars are actually a race of car-shaped aliens.First of all: cars don't have eyes. They speak English because they picked up our language and stuff from the Internet. Eventually, the aliens forgot they were not from Earth and actually believed they were real cars. Where are the humans? Read the above WMG.
The passengers are still in the cars.They just never leave.
There are passengers, and they have the cars hooked up to their brains.This is why the cars have personalities and voices and can move about freely (jumping included).
Lightning McQueen is Steve McQueen.Continuing the WMG above, Lightning may be Steve McQueen with his brain hooked up to a car. "Lightning" is simply a nickname that he eventually gained after this happened.
Lightning got shocked one too many times by Dr. Mater and lost large patches of his memory.That's why he never remembers Mater's Tall tales even though he was there when they happened.
Lightning is a famous racer in a coma.He was put that way by a terrible racing accident, and the whole movie is a giant dream sequence. When he first comes into this "dream world", it's more of a nightmare for him.
Sally knew that Doc was a racer.During her time staying at Radiator Springs, Sally looked into Doc's garage and discovered his past. She was going to ask Doc about it, but she learned how much he doesn't want to talk about the life that nearly killed him. So she decided to keep it a secret from everyone, especially Doc. This explains why she's upset at Doc for calling the news and the press to send McQueen away. When she said "Best for everyone, or best for you?", Doc realized that she knows. the Industrial Revolution never ended, and machines were given artificial intelligence. They turned against the humans and wiped them out. The Cars universe is a more positive result of this. However, something happened that caused humans to disappear, leaving only the cars.
Most of the above WMGs make no sense because Cars obviously takes place near the end of the 20th century/beginning of the 21st.Seriously? Cars is from a post-apocalyptic wasteland? The passengers are using the cars like the chairs in Wall-E? This makes no sense. Look at the structures, the older cars like Doc Hudson and that really old granny car. There's no way those cars could have survived that far (at least a century) into the future for any of this to happen. The one with passengers in the cars makes a little sense, but remember that a lot of the cars in Radiator Springs remember a time before the interstate. That's in the 1930s, or too far back for your theories to be plausible. I know this isn't technically a WMG but it doesn't fit in any of the above because it applies to tons of them.
Cars is just Andy playing with Hot WheelsThe opening of Toy Story 3 suggests the idea that it's what toys truly experience during playtime. So a bunch of toy cars being played with would experience a whole different world. A toy car resembling Lightning McQueen even appears at Sunnyside.
HARV is a human being.
This movie takes place in an Alternate UniverseThere are car versions of real people like Jay Leno and Arnold Schwarzenegger, there are real places and locations made to fit with it's automotive citizens, and the car versions of other Pixar movies imply that there are car versions of the Pixar crew working on animated car films. So that means that there must be a car version of everyone on Earth throughout history.
The cars are able to move because they are Merchandise-Driven.Rule of Symbolism.
Mater's Tall Tales are all trueExcept for the bits at the end where he says Lightning was a part of them. Mater just says that to mess with him.
The Cars world co-exists with the Thomas the Tank Engine world and vice versa.Think about it. Both universes have Animate Inanimate Vehicles have little to no explanation how they came about, and both have very very little humans present (and in Thomas's case they're rarely shown).
Cars, like monsters, can slip into a parallel universe.Maybe when they go in a garage, they can drive out through the back wall into their world? It certainly makes car wrecks in our world much more horrifying, though.
Cars takes place in the normal Pixar universe, but it goes like this...At some point during the Pixar universe timeline, sentient cars built by the humans rose up and took over. The humans who weren't killed went into hiding in the places that the cars couldn't get to. At some point, though, the Cars universe falls apart. Why? Lack of fuel. They need it to run. They haven't developed many alternative energy sources. Only the richest cars of all could afford to be converted to solar power. Lightning McQueen couldn't, because after his racing career died (when the fuel was running out, racing was one of the first things to go) he spent all his money on car hookers, and car drugs like car-caine. He dies of an overdose, and the rest of the cast who haven't died are forced to live in this apoc-car-lyptic world. Eventually, nearly every car dies off. The few that are left get destroyed by the uprising humans, who saw the rapidly falling car population as their chance to take back over. They do so and rebuild the world, eventually into the futuristic one we see in WALL-E...
Acer's Start of Darkness came after a horrific injury....when Alice's dad tried to park his Skylark in Acer's trunk...
McMissile is......actually Doc Hudson, but altered for his role as a spy car!
Lightning McQueen and Sally are like parental figures to Mater.
Our own world is the Cars world after a Zombie Apocalypse.
Zundapp is an ex-Nazi.
Francesco is Agent Simmons.
Cars in this world can adapt, same way as humans in our world can.It would help explain some things, like how they are still around after all these years.
New cars come from...
Cars and other vehicles "evolve", at a much faster rate than organic life does.Or scientists and engineers figure out ways to improve the species, and then incorporate these designs into the next generation. This is why older cars are different models than younger ones.
The Cars universe is actually a level of "car heaven".Cars from our world that were well-loved by their owners are reborn into this world when they "die".
Rust is a diseaseIt seems like in the two movies, rust can act like leprosy or be an indicator of one's rapid aging. Maybe for Mater's case it relates to the former, his mind can't catch up with the aging and reverts him to a child like demeanor.
The mixed critical reception of Cars 2 was mostly because Bruce Campbell's character got killedCome on, nobody wants to see the Man with the Chin dying.
Red is part animal.He never actually speaks, just occasionally vocalizes and sounds his siren. Since he's a firetruck (and I always imagined elephants would be depicted as firetrucks in the Cars universe), we can maybe assume he's part elephant... After all the tractors are cows and Frank the Bulldozer is a bull, etc. Furthermore Tony Trihull, the lemons' combat ship, is said to be part shark, despite having human dialogue.
