I don’t know about you, but I have definitely wondered how exactly the cars in Cars were supposed to be alive, at least, in the weird half real, half not real world that is Cars. These rad rendering were done by illustrator Jake Parker and he does a much better job of articulating this bizarre thought:
I grew up in AZ and am very familiar with small towns strung along old highways. It struck a chord with me, and left a good message: Slow down, look around, and enjoy life for a moment. However, every other Pixar movie took either a living creature and anthropomorphized it (bugs, fish, monsters, rats) or in the case of Toy Story took inanimate objects and bought them to life, but did so with in the realm of our world. Cars is the only movie they’ve done where they’ve extricated the experience from our world and put it somewhere else completely. And that leads me to the one thing that didn’t sit well with me: the strange machine/flesh hybrids Pixar came up with to populate this world.
I had that exact same thought when I first saw Cars, glad I’m not the only one! I don’t recall them ever needing to eat in the first film, but this at least clarifies some of the anatomical mechanics that could be involved. Now I guess I should watch Cars 2, no doubt with this in mind.
