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 information, it chooses the right __6__ for the intelligent cars, and gives __7__ to the “hands”and “feets”to act accordingly. In this way, the virtual driver controls his car.
　　What is the virtual driver’s best advantage? He reacts __8__. The mini-cameras are __9__ images continuously to the “brain”. It __10__ the processing of the images within 100 milliseconds. However, the world’s best drier __11__ needs one second to react. __12__, when he takes action, he needs one more second.
