Don’t be too surprised if you see a car going down the road without a driver in Beijing these days. It might be one of Baidu’s self-driving cars. Last month, Baidu tested its self-driving cars on open roads in Beijing. Self-driving cars have been in progress since 2010, when Google said it was making such cars. From then on, companies like Tesla, Uber and Baidu tried to make and test their own self-driving cars.

Now, many people really want to buy a self-driving car if they have enough money. They think it will make their life easier. However, every coin has two sides.

Normally, when there is an obstacle (障礙物) in front of the self-diving car, the car will stop. But sometimes it also makes mistakes. In one test, when researchers sent a point of light in front of a moving self-driving car, the car stopped. And in another test, when researchers did it again, the car moved to another road. If scientists don’t solve the problem, some people may use the mistake to do bad things.

So self-driving at least now is still not safe enough. When we use our computers or smartphones, they sometimes don’t work well without any reason. If this happens to a self-driving car the results might be dangerous. So scientists are making improvements to work out the problem.
