Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. The idea of a driverless car is not new. Now there are already cars on the road that can park themselves. But a truly self-driving car, one that can drive itself, is being tested by scientists and engineers. Self-driving cars have already tested on public roads. These cars not only record images of the road, but their computerised maps view road signs, find alternative routes and see traffic lights even before they are seen by a person. By using radars and cameras, the cars can analyse information about their surroundings faster than a human can. In some of the tests, the car learn the details of a road by driving on it several times, and when it is time to drive itself, it can identify when there are pedestrians crossing and then stops to let them pass by. Self-driving cars could make transport safer for all of us by eliminating the cause of most of today’s accidents. Although self-driving cars may seem far off, some people believe that there will be driverless cars in showrooms in about 10 years. 28. What is the main idea of the passage?
