Do you consider "The Road" to be science fiction?

Back in the 1980s, this kind of book and movie would undoubtedly be considered SF. I would put it on the shelf alongside novels like David Brin's "The Postman", Chelsea Quinn Yarbro's "False Dawn", and Pat Frank's "Alas Babylon" and movies like "The Rover" and "The Book of Eli". All Post Apocalyptic tales but lacking mutants, cyborgs, zombies, aliens or any other trappings of traditional SF. These are stories that present a more realistic view of what life would be like after an Apocalyptic event.

Back then in the 80s, there was no other place to put them except SF, but now with so many genres and subgenres, this type of story seems to have lost its place in literature.

These books are harder to find, now, unless you count the many "Prepper" novels, that focus on the preparations and weapons and survival gear and have a protagonist who embodies the Prepper lifestyle. A story like "The Road" with everyday people forced to survive without elaborate bunkers and skills is not the same as a Prepper novel at all.

Where would you classify stories like "The Road"? Do you consider them SF, or just a type of mainstream novel, or in a genre or subgenre of their own? Do you think there is a market for realistic Apocalyptic novels?
