Question

Have you ever seen a car without a driver? It sounds crazy, but these computer-driven driverless cars will soon be filling roads near you. Some big companies have been designing and testing these cars. The first robot-taxis with no drivers are planned to hit the road, and it is said that more than 10,000 driverless vehicles will be in use around the world by 2021.

The cars have sensors (傳感器), including radar and GPS, which allows the cars to “ see” moving objects, like cars and people, in order to work out when to go faster or slower, or when to stop or turn. Sensors on the wheels also help when parking, so the car knows how far it is from the curb or other parked cars. Road signs are read by cameras, and GPS is used so the car knows how to get to the place you want to go. All you have to do is to type in the address!

Sound like your idea of heaven? Sitting back, looking out of the windows and even watching a film or reading a book while “driving” would be possible with this new technology. You wouldn’t have to worry about remembering directions to where you’re going. In addition, computers would drive more safely than people—they don’t get distracted by music or friends.

However, there are many drawbacks of driverless cars. Computers would have difficulties making decisions: if a child ran into the road, would the computer choose to hit the child or change direction and potentially kill the car’s passengers? Moreover, some people don’t believe these cars are safe and reliable. They think it’s highly possible for technology to make mistakes, meaning that driverless cars are just as dangerous as cars driven by actual drivers. There would also be many legal (法律的) decisions to be made—should children, or drunk people, be allowed in a driverless car by themselves?

Although being driven around by a machine would perhaps mean that no one needs a driver’s license, saving money for everyone, but many people would lose jobs. Bus and taxi drivers as well as driving instructors may not be needed any more.

Personally, I don’t think I’d ever want a driverless car because I find driving fun. But it’s only a matter of time before they’ll become more affordable and common on our roads.
