Japanese automakers have created a car that gets 300 miles per gallon. Unfortunately these 300 miles are all in Japan and therefore useful only to a handful of local motorists. Engineer Ken Hibachi hopes to design a fuel efficient vehicle by restructuring roads in such a way that every trip will be downhill in both directions. "All that coasting will save on fuel costs and improve air quality" remarked this innovative man of science.
