Here are two types of cars that may some day take place of today's big cars. If all the people drive such
cars in the future, there will be less pollutions in the air. There will also have more space for parking cars in
the cities, but the streets will not be so crowded. Three such cars can fit the space now need by one car of
the usually size. The little cars will spend much too less to own and drive. Driving will be safe, too, because
these little cars can go only 65 kilometers per hour. But it will not be of any use for long trips.
