Over a million people around the world lose their lives to car accidents （事故） each year.
While nearly all of these deaths are the consequence of human mistakes, there are no good ways to reduce the number of deaths. Surely one of the best plans is driverless technology.
Driverless cars are no longer an idea of the future. With the technology for the driverlesscar already developed for quite a long time, and some important inventions already seen in some cars, the driverless car could soon be with us.
This is wonderful because driverless technology is expected to reduce the number of roaddeaths. A research group in the United Kingdom says that driverless cars will lead to 2, 500fewer road deaths before 2030.
How are driverless cars safer? Firstly, driverless cars can help manage traffic. By using communication technologies to "talk" to each other, driverless cars find the best roads. Information such as distance（距离）between cars, traffic and time is sent to the cars.This means fewer chances of these cars running into each other. Secondly, the use of driverless cars means fewer accidents will happen because of human mistakes. For example, accidents caused by little sleep or drunk driving will be avoided.Finally, the driverless technology of the future, is expected to be more reliable（可靠的）than a human driver.
If lives can be saved by driverless cars, let's hope these cars will be on our roads very soon.
