Crash and Menippean Satire

The repetition of and emphasis on Ballard's accident is interesting. This alone clearly demonstrates the obsessive nature of both Ballard and the novel. The scene - both the physical place and the event itself - are very important to Ballard. He revisits this scene over and over, and goes so far as to involve other people in his fantasies about it. He drives past the scene of the accident time after time and derives some strange sort of pleasure from it. This particular crash seems more important to him than crashes in general. He gets the exact same car after his is wrecked, goes to visit his totaled car, starts a relationship with the woman whose husband he killed in the crash, and, of course, revisits over and over the place the crash occurred. The idea of negative theology is interesting as well. Though the concept is fascinating, I've had a hard time directly relating it to Crash. What is the belief that is absent, that suggests an unnamable belief?
