43． Could you imagine being in a car driven by a computer，not a human？Recently，China has made a big step toward self-driving cars.
Since August，driverless taxis can run on roads in Wuhan，Chongqing and Shenzhen.Self-driving cars bring 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.For disabled or blind people，self-driving cars can also help them get around more easily.
According to US Centers for Disease Control and Prevention，more than 1.35 million people are killed on roads around the world every year.Many more are injured.Self-driving cars could reduce road accidents by 90 percent and save governments a lot of money，said the website TechDim.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.
But 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 could.Also，during weather events like heavy snow，self-driving car s would struggle（费力）to see the lines on the road.It might lead to an accident.The car's computer system could also get hacked（非法入侵）by someone，causing it to crash or change its destination（目的地）.
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.
