Could you imagine cars driving without human drivers?Recently, China has made a big step toward self-driving technology. This August, more and more driverless taxis run on roads in many big cities in China.
Why do we develop self-driving cars? Self-driving cars give us many benefits. They use computers to sense the things around them and make better use of space. This means fewer traffic jams and better parking of cars. Many people cannot drive for various reasons, including age, disability, or lack of experience. Now, they can get around more easily. Driving becomes more convenient.
According to a research, each year, over 1. 3 million people die in car accidents around the world, and many more get hurt. Self﹣driving cars can reduce （减少） road accidents by 90% and save a lot of money. The main cause of car accidents is human mistakes. By using computers, self﹣driving cars don't make poor decisions or lose attention like humans do. They can improve driving safety.
But self﹣driving cars aren't perfect. If something unexpected on the road happens, self﹣driving cars can't react （反应） as fast as a human driver can. Also, during weather events like heavy snow, it will be difficult for self﹣driving cars to see the lines on the road. It might lead to an accident. The computer system in the car can also get hacked（非法入侵）by someone, causing it to crash.
It's clear that there is a lot of work to do to make self﹣driving cars a common and safe sight on our roads. And China is taking the lead in making this happen.
