Way back in the Race for Ridiculism days, I did a coin toss on whether to sumbit these guys or objectum-sexuals* as my doc. Clearly I didn't pick car fuckers, and I'm alright with that, because BomberJacket did a MUCH better job than I ever could have. I never even knew the exhaust huffers were a real thing. I was genuinely surprised at how bad the car fuckers are at actually acting on their fetish, though. I guess that's mostly because fucking a tailpipe is about as safe as sticking your dick in a hot circular blade, but with the additional fun of carbon monoxide.
What really got me was Totally-Not-Jason talking about exhaust fumes going on this teenage girl's feet. The vore and inflation shit seems to be part of the common strain of Internet Fetish Virus, but mixing car exhaust fetish with feet just seems...bizarre.
*(Objectum-sexuals do not need to be an episode, btw. It turns out it's way less "weird fetish" and way more "genuine psychological trauma" than I thought.)
