One thing I always look at in post-apocalyptic literature is how they treat transportation: notably, are people still driving cars and how long can they do so and under what conditions?

Entering our current oil crunch, I think it’s obvious how fragile the ecosystem around cars are, but just letting the car sit unused and untreated for as little as a month can start to introduce\ problems. The idea that you can just pop into a car that’s been abandoned for 3 years, pull the keys out from behind the visor, and start driving is unrealistic.

  • Best: The Postman. We’re back to walking and riding horses.

  • Good: The Last of Us, Season 1. People walk or ride horses, when our heroes DO find a working truck, it is treated as the jackpot it is–and I think it even had a spare gas tank in the back to maximize distance traveled to harvest gasoline. Realistically, gas as a fuel for fires would be a valuable enough commodity that it would have been scavenged, but they need to do some traveling and high speed dragons are not available in this genre (Reign of Fire aside).

  • Worst: Jericho. Nuclear explosions in the US pretty much wreck everything and despite the town of Jericho being completely isolated, people just drive their pickup trucks around all seasons long without comment. Horses and bicycles are maddeningly present but rarely used. I think the show thought American audiences could accept a premise where the federal government collapses after multiple nuclear strikes, but not where people in Kansas got off oil dependency–that would be too out there.

      Because there are a lot of parts on the tractor that might need to be repaired and replaced. Even if you had access to everything you need, how many people are going to know how to do it?

      And timing is critical in faring, so you’d have to get the tractor repaired quickly if anything goes wrong.

      So if you lose one person or can’t fix one part quickly enough, your entire agriculture system falls apart if its based around a tractor.

      A system built around human labor or even animal labor is much more resilient.

        We were talking about carbon inputs and biodiesel, not reliability. Growing biodiesel has no carbon inputs if the farm itself runs on biodiesel.
