I think that a small generator would be a far more likely option for now. I would definately support a small 15 hp generator that randomly spawns in factories or barns. You could still need to repair it, and you could find electrical wire, lightbulbs, and sockets to light up a building or a base camp. Besides, it should make slightly less noise than an ATV or car, but would definatley attract players or zombies by the light or noise. Hooking up homes or large towns is unrealistic for now as stated in other threads, but this should be something that they consider adding.
