What will the car be like in the future? Maybe we can sit in a car that can drive itself,

About 40 years ago* scientists from the United States started to develop self-driving cars(無人駕駛汽車)   .The most famous recent one was made by Google in 2009. There are cameras and radars(雷達(dá)) on the top of the car. They allow the computer in the car to draw a 3D map of the environment. Chinese scientists have also successfully developed a self-driving car. The car made,a trip from Changsha to Wuhan.

Is a self-driving car safe? A recent study shows that robots make safer drivers than humans. If only 10% of cars on the street are self-driving,they will save 1,000 lives(生命) every year. If 90% of vehicles (交通工具) are self-driving, 21,700 lives will be saved a year. However,a self-driving car is expensive and each costs about $ 100,000. So it is impossible to be very popular in the near future.
