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.
Or, with the number of very loud vehicles in Lord Humungus' group, the crossbow man probably figured Max's V-8 interceptor engine noise was the sound of a fellow wasteland raider and didn't warrant his attention.
