Discover the "Piggyback Driver", a helmet that allows children to drive their parents! With two handle, this prototype is carried by an adult with a child on his shoulders during a walk. Thus, the child can take control of an adult. By turning the handlebars, it lights blinking LEDs and causes a vibration in the helmet to tell adults what side he should turn. Also, a fun "Turbo" button produces sound and brings out flashes of light. The helmet is also equipped with a horn to warn passers-by and not a detector. More walking, the faster the LED flash. The Piggyback Driver is a prototype designed by the laboratory Party New York.
