Given the intense sexualization of automobiles in advertising -- especially notable at the time Ballard wrote these stories -- I'd say he's right on the money on that one. Yes,
The Atrocity Exhibition is one of, if not
the, most challenging of his books. Oddly, except for "The Recognition", which I encountered in
Dangerous Visions, the stories that make up
The Atrocity Exhibition were my first encounter with Ballard's work. I came across a few of them in places such as the
Best of New Worlds anthologies Moorcock edited, and Judy Merrill's
England Swings SF, and was immediately caught up in what he was doing. As a result, this has remained among my favorite Ballard books, and I'd still say it's one of the most innovative, imaginative, stimulating, and, yes,
dangerous things to come out of science fiction in the entire history of the field....
Incidentally, I'm curious: which edition do you have? There was a later edition with some additional stories and annotations by Ballard, as well as some very appropriate -- and therefore disturbing -- illustrations....
