①Could you imagine being in a car driven by a computer, not a human? Recently, China has made a big step toward self-driving technology. Since August, driverless taxis can run on roads in Wuhan, Chongqing and Shenzhen.
②Why do we develop self-driving cars? Self-driving cars have many advantages. They use computers to sense the things around them and make better use of space. This means fewer crowded roads and better parking of cars. For disabled or blind people, self-driving cars can also help them get around more easily.
③According to US Centers for Disease Control and Prevention, each year, more than 1.35 million people are killed on roads around the world. Many more are hurt in accidents. Self driving cars could reduce road accidents by 90 percent and save governments a lot of money. The main cause of car accidents is human error (错误). By using computers, self-driving cars don’t make poor decisions or lose attention like humans do.
④But self-driving cars aren’t perfect. If something unexpected on the road happens, self-driving cars can’t react as fast as a human driver can. Also, during weather events like heavy snow, self-driving cars wouldn’t see the lines on the road easily. It might lead to an accident. The car’s computer system would be broken by someone, causing it to crash or change its direction.
⑤It’s clear that there is a lot of work to do to make self-driving cars a common sight on our roads. And China is taking the lead in making this happen.
