Lefty RX

The Lefty RX was a toy Nintendo released in 1972. It was an RC car that featured 3 different variants (each with three colors and each sold separately) for ¥4,980, ¥5,800, and ¥6,800 (depending on the model) each, a bargain for a type of a toy that was usually very expensive at the time. Gunpei Yokoi was given to task to make the product as cheap as possible, and succeeded in this goal by using only one frequency, which consequently only allowed the vehicle to turn left (hence the peculiar name). While it may seem to be an odd decision, users could still organize races by creating a track that was devoid of any right turns, or by simply performing a u-turn.
