Some day little cars may take the place of today's cars. If everyone 1 such a little car in the future, there will be less pollution in the air, there will be more parking space in cities, and the streets will be 2 crowded. The space now for one car of the usual size can hold 3 one such little car. The little cars will . 4 much less to own and to drive. Driving will be 5 , too, because these little cars can go only 50 kilometers an hour. The cars of the future will be fine for going 6 the city, but they will not be useful for going far away. The little car needs only two batteries- one battery for the motor, and 7 for the home and the lights. If we still 8 the big cars along with the small ones, we will need 9 two kinds of roads. Some roads will be used for the 10 cars, and other roads will be needed for the small slow ones.
