In the new Mad Max: Fury Road,
after they hook up with Furiosa's clan, they load up the motorcycles and prepare to abandon the war rig and ride across the salt. Furiosa explains the plan to Max.
She states that they have enough fuel and supplies to ride for 160 days. She says it casually and it is repeated several times, so it's clearly not a mistake.
This is an unbelievably long time to ride without resupplying. Even if the bikes were solar powered and they had stillsuits that captured all but a liter of water, that's still an unmanageable 160 kg of water each.
Is there anything in the film (or other Mad Max material) that could explain how a group on motorcycles could carry enough food, water, and supplies to ride for 160 days?
