Oh dear goddess that article was lame. I honestly want my 3 minutes back. Not only did I have to click through so they could get more advertising revenue, but they had a unicycle in there.

I'm sure that we could do better here with minimal effort. The criteria aren't that hard to establish:

1 - Is it bulletproof?
2 - How difficult is it to fix?
3 - Can it haul enough stuff to keep you alive?
4 - How many were made? (makes spare parts easier to get)
5 - Can you comfortably sleep in it so you're a bit safer?
6 - Will a lack of roads cause problems for it?
7 - Can you mount weaponry on it?
8 - Did the A-Team ever use a similar concept.

This means things like Jeeps and VW Beetles are in, but not necessarily preferred. Xs, oddly enough, might be out because they're difficult to work on.

Unicycles, however, offer no value whatsoever.
