The idea of getting gas from other cars or finding bikes never comes up. The four main characters in Carriers are perfectly willing to shoot innocent people for their gas, even though the world is almost entirely intact.It doesn't explain why nobody else has them, though. The Book of Eli could potentially have this be a Justified Trope, since the main character is blind, even if he also has a Disability Superpower.However, given the pace at which the infected run (and never seem to tire), this is at least partially justified. Particularly strange in that, as the title of the film says, the movie takes place only a month after. Ironic, since Jim's character was a bicycle courier before the accident that got him into a coma in the first place.
