Behind the scenes
The title of this challenge comes from the opening monologue of the movie Mad Max 2: The Road Warrior:

"Their world crumbled, the cities exploded... A whirlwind of looting, a firestorm of fear... Men began to feed on men...On the roads it was a white-line nightmare.

Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice."

- Narrator, Mad Max 2
