You would never make any friends in it.
Moot point after the zombie apocalypse I suppose.
just read two great post apocalypse books , The Road (by the greatest living American Author) in which the hero walks and the Dog Stars (find it , read it) in which the hero flies a Cessna, slow reliable, fixable. (he also teams up with a survivalist who has been stockpiling ammo since God was a lad).
Point is neither of them are reliant on land based motorised transport.
If it's a nuclear apocalypse then a diesel will work once you bump start it but isn't one of the side effects of a thermo nuclear device , that the magnetic field fries all alternators and starters?
