In "Parks and Rehabilitation", the misplacement of the Norge Porthole accidently set off a chain reaction of artifacts. This RC car was knocked from its shelf by a soccer ball, causing it to speed along the ground until it collided with the crate containing Leonardo da Vinci's Gargoyle. This seemed to activate the automaton.
The accompanying data-tag states that the RC car controls its own speed and direction. It also induces wandering into dangerous situations, though whether this is referring to the car or the user is unclear.
