When I first read about it in Popular Science, the idea was attributed to an engineer whose Lotus Esprit got outrun by a 2CV in the rain. The obvious answer was to put it on skinny tires, but if he did that, it would handle like a 2CV in the dry, so he used eight of them on special wheels. Goodyear later refined the idea into the Aquatred.
