My only doubt is: why on hell did Pappagallo, the Mechanic and Warrior Woman embark on such a death trip if it was mathematically SURE they would have been killed and the gas tanker stolen?
How did they persuade Max to drive a gas tanker throughout the Wasteland AD LIBITUM, until the Marauders get tired and resourcefulness?

"Max... they will chase you... but when their cars would be running empty on gas, you win".
Is it supposed to work as a race?
