无人驾驶汽车 Babies born after 2017 may never need to take a driving lesson because of the development of selfdriving cars. Some scientists say that selfdriving or driverless cars(无人驾驶汽车) may hit the road within 15 years, and it is possible that driving may become unnecessary(不必要的), or more relaxing and enjoyable. Companies like Google, Baidu, Apple and Alibaba are working on driverless cars. But, if the tests are successful, these electric selfdriving cars could be put into use very soon. This kind of cars may change the way we live in the future. All you have to do is typing in your address! According to Baidu, the driverless technology has the following four advantages. Firstly, driverless cars are actually safer. In China, there are more than 500 deaths caused by accidents. With driverless cars, the number will decrease by 100 times. Secondly, driverless cars are more efficient(有效的) than manned cars. Thirdly, driverless cars follow the traffic rules. Therefore, traffic controlling will be easier. At last, the cost of transportation will be reduced as the labor cost becomes less. There are many different technologies needed to make a successful selfdriving car. The most difficult technologies of all are environmental perception (感知), behavior prediction, planning control, HD mapping, and exact GPS. 1.
