On a fine day last month, there were many small cars parking in the People's Square. They looked more like colorful eggs than ordinary cars. The cars were electric, rolled(滾動)on two wheels instead of four and could carry only two passengers. Thanks to their small size，six of the cars would share a parking spot. If the idea of parking such a small car makes you nervous, don't worry about that. These cars can park themselves and return to the owner controlled by a cellphone.

The car is called the EN-V. It is designed by the General Motors. One day, such small, electric cars might safely carry people around， especially in crowded cities. Scientists and engineers are finding new ways to make cars safer,smarter and more efficient or use less energy. New


 

cars may help you keep healthy by telling you to take medicine. Cars may even talk to other cars,your computer, your phone and so on.
