I write about cars all the time. I also write fiction, some of which you could term "horror." Recently, I have mashed the two together and the results have been great
The first example is a piece that was just published on the Carzz website, called "If Horror Movie Villains Were Cars." Read it for yourself here. I took considerable creative liberties and figured out what cars are like some famous horror movie villains, both from modern flicks and some classics.
The second example is also on the Carzz website, but it takes a look at the rules surrounding how cars are used in horror movies. Read it here. Just like the trope where the girl being chased by a knife-wielding murderer will always run upstairs, there are some hard-and-fast rules about how protagonists and villains interact with vehicles in horror flicks.
