The part where she had to make a motorcycle out of a car was a reference to a very real event that happened to Emile Leray in 1993.
Traveling in a car across the Moroccan desert, he came across an army checkpoint and told him to turn around due to the ongoing fighting in the region. He pretended to turn around and went around the army block off road. This caused him to hit a huge rock and break his front axis and chassis. Over the course of 12 days 11 nights, he built a motorcycle out of salvaged parts from the car.
