Trivia: You might have to look close, but the Gyro Captain's copter is completely covered with pornographic pictures. It took many viewings for me to notice this. Apparently he's very sexually motivated, as later in the movie he complains that the only thing he really misses from the old world is lingerie, and the only reason he joins the escapees in the end is because he wants to be with the cute blond girl.
Suggested correction: Completely covered is an exaggeration. There is one picture on one of the rear fins. Also, that's an assumption about his motivation to join the escapees. It could just as easily be said that he's found people who accept him, and even make him their leader. That could be very welcome to someone who's been alone for so long.
Plot hole: Max drives from the hillside to the crashed car to save the occupants but the guy with the crossbow doing up his boots somehow doesn't hear Max's V8 engine approaching, or hear Max get out and sneak up on him, this area would be quiet and Max must have parked nearby to get the injured man to his car.
Suggested correction: Spoken like a person with no hearing disability. Maybe the guy was deaf.
Factual error: Mad Max turns on his engine blower with a switch. The blower in Max's car is driven by a belt attached to the engine itself. The only way to turn it off is to turn off the engine. It is possible to put the blower on an electric motor, but turning it off would simply shut off the oxygen and fuel, both of which are pretty important in an internal-combustion engine.
Suggested correction: Switch-controlled superchargers are real devices, for example the commonly used Toyota SC12 and SC14. They use an electrically controlled magnetic clutch to engage or disengage the pulley. When such devices are disengaged (off), a bypass valve on the air intake redirects air around the supercharger via some extra plumbing. Also, fuel doesn't go through the supercharger - it happens below the supercharger stack as normal (in the carburettor or via fuel injection directly in the cylinder head), so that part of the entry is also wrong. For the Interceptor in the movie, it's true that the Weiand supercharger isn't set up this way. It's all fake for convenience - just a hollow shell with a regular carburettor inside. The switchable effect is simulated through the use of a small water pump connected to the front of the blower drive shaft, driven by a tiny electric motor under the hood. But there is no technical limitation to having a real supercharger controlled with a switch, just like Toyota's SC14.
Other mistake: The amount of vehicles leaving the compound at the end doesn't make sense and the amount of fuel they carry is far less than they could carry in the tanker. The amount of vehicles they use apart from the bus being used as the gate are never seen parked in the compound throughout the film, they just appear when needed.
Suggested correction: At the end there are seven vehicles (including the bus) leaving the compound. That's the same number seen right at the end. It's quite possible for six vehicles to have been inside the compound. Also, the being able to carry less fuel than in the tanker isn't a mistake; it's just a fact. They sacrificed all that extra fuel in order to be able to leave with any. That was the plan.
