modernmechanix: Speedy Motor-Cycle Car Runs on Two Wheels.

Via modernmechanix.com;

"WHETHER it’s a car or a motor cycle would be hard to say, but the inventor of the novel vehicle above declares it has the advantages of both. In motion, it rides upon two wheels, guided by a steering wheel. The driver experiences a pleasant swaying sensation as the machine tips like a plane or motor cycle for the turns. When the driver stops, a pedal lowers a pair of small auxiliary wheels at the sides for support. The photograph shows the odd gas buggy being driven by a mechanic in a tryout run at Miami, Fla. Another model has a seat for a passenger mounted behind that of the driver."
