Mad Max 2 (1981) - 4 questions

Question: Where exactly are Humungous and his men getting their gas from? Given the amount of vehicles they have, it would take a fair amount of fuel to run them. But there is no explanation as to where they are getting it.

Answer: The same way Max did until finding the fortress- scavenging, and when possible, attacking other vehicles like they attacked Max at the start of the film. They take what they can find.

Question: How did the gyro captain and especially the little boy get back to the rest of the group from the refinery without attracting Humungus and his crew? The caravan left in the opposite direction like 15 minutes before, mad max had no vehicle to drive back, the boy can't drive at all, and the gyro captain crashed his gyro. But in the end the boy and the gyro captain manage to get back into the caravan before sunset without Humungus following.

Answer: The gyrocopter was just unable to fly. It still could roll along the ground. It is possible that he repaired it to get back to the rest of the group. As for Humungus and his minions, I'm pretty sure Humungus was killed in the impact with the truck that Max was driving. The few surviving minions probably lost interest in the whole affair when they lost their leader which one can assume when you see them turn around after seeing the spectacular collision and not even bothering to see if anyone survived.

Question: What type of car is the red Hummungus car with the bat on the hood that Max destroys during the chase?

Answer: The car is either a FORD XA Falcon or Fiarmont Coupe, built in the early 1970s. The X series falcons were only availible in Australia, and you'll find most of the vechiles in these movies (the cars at least) are some hybrid of the Falcon.

Question: Early in the movie Max finds an abandoned truck with graffiti on its side saying "The Vermin Have Inherited the Earth". Is this a reference to something?

Answer: Maybe the Judeo-Christian bible "The meek shall inherit the earth" (Matt 5:5). Not much of a stretch that someone in that environment would change meek to vermin.
