Does this constitutes a ticket for DUI?

In Abbotsford, Wis., in August, Harvey Miller, 43, and Edwin Marzinske, 55, were both ticketed for DUI while driving the same car. Miller has no legs but was steering; Marzinske was operating the foot pedals. Hence, both men argued to police that neither of them was, by himself, "operating" the car.
