Question

Babies born after 2017 may never need to take a driving lesson because of the development of self-driving cars. Some scientists say that self-driving or driverless cars(无人驾驶汽车) may hit the roads within 15 years, and it is possible that driving may become not necessary, or more relaxing and enjoyable.

Companies like Google, Baidu, Apple and Alibaba are working on driverless cars. If the tests are successful, these electric self-driving 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 the address!

According to Baidu, driverless technology has the following four advantages. Firstly, driverless cars are actually safer. Secondly, driverless cars are more efficient(有效的) than manned cars. Thirdly, driverless cars follow the traffic rules. Therefore traffic control will be easier to achieve. 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 self-driving car. The most difficult technologies of all are environmental perception (感知), behavior prediction, planning control, HD mapping, and exact GPS.
