　　An Intelligent Car
　　Driving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all 1 and can control a fast-moving car. But how does an intelligent car control itself?
　　There is a virtual driver1 in the smart car. This virtual driver1 has “eyes,” “brains,” “hands” and “feet,” too. The minicameras 2 each side of the car are his “eyes,” which observe the road conditions ahead of it. They watch the 3 to the car’s left and right. There is also a highly 4 driving system in the car. It is the built-in computer, which is the virtual driver’s “brain.” His “brain” calculates the speeds of 5 moving cars near it and analyzes their positions. Basing on this information2, it chooses the right 6 for the intelligent car, and gives to the “hands” and “feet” to act accordingly. In this way, the virtual driver controls his car.
　　What is the virtual driver’s best advantage3? He reacts 8 . The minicameras are 9 images continuously to the “brain.” It 10 the processing of the images within 100 milliseconds. However, the world’s best driver 11 needs one second to react. 12 , when he takes action, he needs one more second.
　　The virtual driver is really wonderful. He can reduce the accident 13 considerably on expressways. In this case, can we let him have the wheel4 at any time and in any place? Experts 14 that we cannot do that5 just yet6. His ability to recognize things is still 15 . He can now only drive an intelligent car on expressways.
