Based on the idea that children with autism may find human faces confusing since they are unpredictable due to the fact that the autistic brain cannot cope with unpredictability. In Baron-Cohen's theory, children with autism are strong "systemisers" and faces are hard to systemise. In contrast, children with autism have a preference for predictable systems. The Transporters therefore focuses on mechanical vehicles that only travel along tracks, because they are highly predictable systems. Grafted onto these animated vehicles are real human faces.
