In the last third of the film: Max is seriously wounded and his car wrecked after being run off the road by Wez in Lord Humungus's nitrous oxide-equipped car. One of the Marauders kills Max's dog with a crossbow before Toady's attempt to siphon the fuel from the Pursuit Special's tanks triggers the car's self-destruct, which kills both Marauders during the explosion.
Contrary to what another comment said re: "is someone sexually assaulted," the rape and murder of a woman is shown on screen. Starts ~21:45, ends ~23:45. (There is a lot of cutting between the rape and other action happening at the same time, during those two minutes.)
It is strongly implied that Wez and his blonde companion are partners. When the Feral Kid throws his boomerang, Wez dodges it but it kills his blonde lover.
Portrays gay men as violent, predatory, and uncivilized. Their presence is used to illustrate “downfall of morals” and they’re killed by a straight cop.
