What would the world be like if cars could drive themselves?

Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping. But none of them is worried about the road ahead.

Well, all of these could be the future of driving. There are several companies, for example, Google, working on driverless cars. So far, no Google self-driven car has got a traffic ticket but some of them have been in accident when other cars hit them.

These cars are now still in the testing stages (阶段). If the tests are successful, these electric (电动的), self-driven cars could be put into use very soon. But how is it possible for a car to drive itself? Cars already have many features (特征) allowing them to replace drivers during certain situations. Some features include cars being able to park themselves, or slowdown when they notice other cars close by. They can also control the speed if there are dangerous conditions.

Scientists believe that with the help of wireless signals (无线信号), cameras and GPS, it is possible to create a safe self-driven car very soon.

Usually serious road accidents happen because of careless drivers or dangerous conditions. The self-driven car may be able to stop this. However, some people do not like the idea. They think that technologies can also be mistakes.
