What is a car crash?

This passage from "White Noise" by Don DeLillo is about car crashes. Because Dan and Betty and I are working on racing games, I thought that this passage might shed some light on why we enjoy the spectacle of a car crash.

"How is your car crash seminar progressing?"
"We've looked at hundreds of crash sequences. Cars with cars. Cars with trucks. Trucks with busses. Motorcycles with cars. Cars with helicopters. Trucks with trucks. My students think these movies are prophetic. They mark the suicide wish of technology. The drive to suicide, the hurtling rush to suicide."
"What do you say to them?"
"These are mainly B-movies, TV movies, rural drive-in movies. I tell my students not to look for apocalypse in such places. I see these car crashes as part of a long tradition of American optimism. They are positive events, full of the old 'can-do' spirit. Each car crash is meant to be better than the last. There is a constant upgrading of tools and skills, a meeting of challenges. A director says, 'I need this flatbed truck to do a midair double somersault that produces an orange ball of fire with a thirty-six-foot diameter, which the cinematographer will use to light the scene.' I tell my students if they want to bring technology into it, they have to take this into account, this tendency towards grandiose deeds, toward pursuing a dream."
"A dream? How do your students reply?"
"Just the way you did. 'A dream?' All that blood and glass, that screeching rubber. What about the sheer waste, the sense of a civilization in a state of decay?"
"What about it?" I said.
"I tell them it's not decay they are seeing but innocence. The movie breaks away from complicated human passions to show us something elemental, something fiery and loud and head-on. It's a conservative wish-fulfillment, a yearning for naivete. We want to be artless again. We want to reverse the flow of experience, of worldliness and its responsibilities. My students say, 'Look at the crushed bodies, the severed limbs. What kind of innocence is this?' "
"What do you say to that?"
"I tell them they can't think of a car crash in a movie as a violent act. It's a celebration. A reaffirmation of traditional values and beliefs. I connect car crashes to holidays like Thanksgiving and the Fourth. We don't mourn the dead or rejoice in miracles. These are days of secular optimism, of self-celebration. We will improve, prosper, perfect ourselves. Watch any car crash in any American movie. It is a high-spirited moment like old-fashioned stunt flying, walking on wings. The people who stage these crashes are able to capture a lightheartedness, a carefree enjoyment that car crashes in foreign movies can never approach."
"Look past the violence."
"Exactly. Look past the violence, Jack. There is a wonderful brimming spirit of innocence and fun."

Heartless, but I can see the truth in it.
