Continuity mistake: Furiousa's face is not bloodied anymore after she is knocked to the ground with a big thud after her tussle with Max. It goes from bloody, to not so bloody during the fight, to non-existent by the end of the sequence. (00:34:40 - 00:36:50)
Continuity mistake: When the Bullet Farmer (now blind) is being driven towards the War Rig, and is indiscriminately firing at Max and co, the weapons he is using change between shots. He starts by firing two MP5's, then two AK-type rifles, then back to two MP5's again. (01:10:33)
Continuity mistake: When Max jumps from the War Rig to the front of the People Eater's limousine the metal accent on the far left of the bumper goes from angled to straight. (01:37:00)
Continuity mistake: In the final chase, we see Max taking the arrow out of his hand and Furiosa pulling the knife out of herself. A few shots later, Furiosa is changing gears and moving the rig to the left of Max's rig. In that shot, the knife is still lodged in her body. (01:39:40)
Continuity mistake: During the final chase sequence when Max is on the front of the Doof Wagon, the wires hanging in front of the speakers change from a single black cable to many twisted multicolored wires between many of the shots. (01:42:00)
Continuity mistake: When Max sits on the back of Furiosa and loads the clip in the gun, the chain is visible around his right leg, but when he fires, the chain is no longer there.
Continuity mistake: Joe's windshield takes 2 bullets and slightly spiderwebs, later there is no damage.
Continuity mistake: The amount of silver paint sprayed on Nux's mouth changes between shots through out the whole film to dark, light and not there at all - it's car paint and should be hard to remove.
Continuity mistake: The amount of black axle grease on Furiosa's face changes all the time throughout the film to very dark, light, and not there at all. In one scene we see her apply it from the steering wheel column in the following scenes it's nearly gone. Axle grease is very hard to remove.
Continuity mistake: The amount of water coming out of the pipes is considerably less when we see it reach the bottom and that's allowing for some drifting off on the way down. The force of the water is different as well, more like from firehose pipes than a waterfall.
Continuity mistake: The large sandstorm that Furiosa charges into is nowhere to be seen minutes before when Nux backs up in reverse.
Continuity mistake: When approaching the rock arch at the end of the film the guys on the motorbikes are waiting, but the shot shows the large arch on the left and the war rig approaching from the other side. The large arch is on the left-hand side when it is blown up earlier, so the war rig is coming from the wrong direction - from the citadel side.
Continuity mistake: When Max gets out the car at the end, we are supposedly seeing this through the POV of the telescope. However, we see two completely different angles that would be impossible to see from the same telescope that is in the same position fixed to the ground.
Continuity mistake: When Furiosa is explaining to Max about the kill switches when the war rig is stopped, she begins to put her mechanic arm on. When the view changes, she is again beginning to put it on.
Continuity mistake: The bloodline between Max and Nux is entangled with the chain, but after the fight with Furiosa, when Max is sitting on her back, there is a shot where the bloodline is free from the chain. Later it's entangled again. Also the line is less than 2 ft long after Nux cut the chain, but at the end, when Max is preparing the transfusion it's much longer.
Continuity mistake: In the end chase the fuel rig starts to explode and Max jams the throttle with the people eater's foot and jumps to the war rig as the fuel rig is completely engulfed in flames and the trailer starts to explode. Moments later when Max is fighting the pole cat, the fuel rig isn't on fire so much and explodes a second time.
Continuity mistake: When Immortan Joe's body is thrown from the car it lies parallel with it, but when the crowd rush in it's now at an angle, with his feet pointing away from the side of the car.
Continuity mistake: Towards the end of the film, when Max is fighting the guitar playing doof warrior on the doof wagon and the guy loses his guitar, it then cuts to a front shot of the action on the vehicles in front of the 'band wagon' but in the background the guitar guy is still playing, it then cuts back to Max fighting him without his guitar.
Answer: The truck was stuck in the sand and they had to use the tree to winch it out - the tree was used as an anchor. The weight of the truck and soft sand pulled the tree out.
