Oh, I thought he said, "A girl teaching her son how to ride a bike". I should have paid more attention. I thought this would be serious at first. It actually kind of was towards the end. The animation was a tad off putting. It did fit the goofy tone.
I guess the instructor was wrong after all. I love "Mad Max: Fury Road" so much. Characters lose their arms and legs a lot. I didn't know it would be this long. It was worth the length.
