Jenny's adventures are part of a DVD for autistic children released this week in the United States called The Transporters.
The DVD teaches autistic children how to recognize emotions like happiness, anger and sadness through the exploits of vehicles including a train, a ferry, and a cable car.
Autism, Baron-Cohen believes, is a condition where people perceive systems and patterns while remaining almost oblivious to other people and their feelings.
"To teach autistic children something they find difficult, we needed an autism-friendly format," Baron-Cohen said. Autistic children are particularly drawn to predictable vehicles that move on tracks like trains and trams.
Other experts said the video was not a replacement for working and playing with real people.
