    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.1.

So how? The cars have sensors（感应器）all around which can find other cars and objects in the road. Road signs are read by cameras, and satellite navigation systems（卫星导航系统）are used so the car knows how to get where you want to go. 2..Finally, a central computer system takes in all the information that it receives from the sensors and cameras and works out when to speed up, stop and turn.

Sound like your idea of heaven（天堂）? 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.3. they would obey the rules and have quicker action times when in dangerous situations.

4..Computers would have difficulties making ethical（道德的）decisions: if a child ran into the road, would the computer choose to hit the child or turn suddenly in the risk of  killing  car’s passengers? Moreover, I personally find driving fun 一I’d miss  driving a car myself. 5.. Should children, or drunk people, be allowed in a driverless car by themselves? Or would there need to be a person with a driving license in the car at all times?

I’m not certain I’d want a driverless car 一 but it’s only a matter of time before they’ll become more affordable and popular on our roads.

D:All you have to do is type in the address!
