Unless you forgot (perhaps you've read too much revisionist historiography):
Rock and roll is evil.
Perhaps most interesting in this film is the way the car out-acts all of the paid actors. The special effect where the car fixes itself is actually pretty good, so you can tell where most of the money went. It's probably one of John Carpenter's worst films, with the visual panache of a one-legged dancer; the panning is graceless and the palette a consistent rust-manure. But it is enjoyable. You have to love a movie bold enough to begin and end with "Bad to the Bone" (before it was used in everything from Terminator to Married With Children). Even perennial favorite Harry Dean Stanton puts in an appearance. Plus, some of the car fetishism recalls Kenneth Anger's Kustom Kar Kommandos (1965). Twin engines become excited breasts. The trunk becomes a firm ass to be caressed. And the cockpit is full of all kind of yummy knobs and levers with which one can pleasure the warm and vibrating lover. Mmmm. No wonder it makes a girlfriend jealous.
