Alan Alda visits the research labs and testing tracks of the Big Three auto makers to find out what people will be driving 10-20 years from now. Fuel efficiency and alternative fuels are the future, and Alda test-drives a gasoline-electric hybrid that's already on the road, as well as several hydrogen-fueled cars still in development. The search for a quiet, fast, safe, exciting and non-polluting fuel-cell car takes Alda from Germany to California to Iceland, which is attempting to become the first nation to entirely replace imported petroleum with domestically produced hydrogen. watch
