The vampires are destructive and vindictive—they don’t kill Neville, so they satisfy themselves by destroying his car instead. But notice that Matheson parallels the vampires’ mindless destruction with Neville’s: for no logical reason, Neville takes his pistols and fires at his enemies, eventually giving up when he realizes that most of the vampires are impervious to bullets. Neville continues to be haunted by the death of his wife (and, implicitly, his child). He’s not a vampire, but he’s living a depressive, isolated life—a fate that is, perhaps, even worse than being a vampire.
