Depends on whether or not it is considered to have four wheels. If it has four wheels, it is an automobile, regardles of how you sit in it. Motorcycle are designated as having not more than three, and not less than two wheels. Do they operate with independent suspension? Or is it two tires munted on a common rim? In any case, the Dodge Tomahawk was never meant to be a production vehicle. It was a design experiment. IIRC it was only ridden once or twice, and I think the test rider said he thought it would be very dangerous, if not impossible, to really give it a good workout. Never made it over 100mph.I think it would be classified as a motorcycle because of the way one sits on it.
Where it gets difficult is when you have three wheels. At that point, the classificaiton varies from state-to-state. It depends on factors such as seat/saddle style, handlebars vs. steering wheel, enclosed or open (and even what constitutes "enclosed"), windshield or not, airbags or not, etc.
