WHEN Joseph Freedman, 44-year-old Philadelphia tailor, lost a leg in an accident, one of the greatest hardships he experienced was being unable to drive a car. Then old “Mother Necessity” was brought on the job, with the result that Freedman designed and built an auto which is operated entirely by hand, save for one pedal. The car is powered by a 2-cycle motorbike engine and goes anywhere on its two motorcycle and two airplane wheels.
