Could 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,2022,driverless taxis can run on roads in Wuhan,Chongqing,Shenzhen…
Why do we develop self-driving cars?Self-driving cars give us many benefits(好处).They use computers to sense the things around them and make better use of space.This means fewer traffic jams(堵塞) and better parking of cars.For disabled or blind people,self-driving cars can also help them get around more easily.
According to the US Centers for Disease Control and Prevention,each year more than 135 million people are killed on roads around the world.Many more get hurt.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.By using computers,self-driving cars don't make poor decisions or lose focus like humans do.
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 could.Also,during weather events like heavy snow,self-driving cars would be difficult 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(景象) on roads.And China is taking the lead in making this happen.
