Screwing up "The Naming"

In Gaiman and Pratchett's Good Omens, they claim that "the Naming" would give an object its purpose, its objective.

If that applied to the world of automobiles, then the Oldsmobile folks seriously screwed up when giving their new SUV its name--they called it, of all things, a Silhouette. You'd think that with a name like that, it would be a sleek, smallish SUV, but the truth is nothing of the kind. We're not talking about Unimog-level atrocity, but still, an SUV just really shouldn't be called a Silhouette.
