The climactic chase as Lord Humungus' horde pursue the oil tanker driven by Max. Arguably the most memorable part of the whole trilogy.
Max leaning out of the rig and shooting the driver of a pursuing car, causing it to swerve and take out many other vehicles.
Not to mention The Reveal at the very end of the pursuit: There's no fuel in the tanker that Lord Humungus went through so much trouble to capture.
During the chase one of the gang members on a motorcycle collides with a car and is launched off the bike tumbling end over end through the air. This breathtaking stunt was actually performed improperly, with the impressive tumbling resulting in a broken leg for the stuntman, but was left in the final cut due to the awesomeness.
The Gyro Captain getting the drop on Max when they first meet, looking to steal the gas from Max's Cool Car. Max tries to trick him and reach for a weapon under the car, but the Captain is smart enough to figure "A fellah, a quick fellah, might have a weapon under there." And then Max's dog gets the drop on the Captain.
The opening chase, while more understated than the one in the first film, shows off Max's driving skills as he runs two different vehicles off the road and bluffs Wez into fleeing with his empty shotgun.
"Last of the V8 Interceptors! A piece of history... Would've been a shame to blow it up."
One of the nameless colony-members strapped to the front of Lord Humungous's vehicle remains Defiant to the End, chastising his broken-willed companion for his groveling and telling the other colonists behind the walls to give the Marauders nothing. Wez has to headbutt the guy to make him shut up.
