Soon technology will provide smart cars: cars that virtually drive themselves. A computer in the car determines the speed and route to the desired destination. The computer is in continuous contact with a global positioning system and other
technologies that will provide extremely accurate information about the location of the car, other cars on the road, congestion, accidents, and so forth. The human driver will be little more than a passenger. Smart cars promise to make driving safer, quicker, and less expensive.
First of all, smart cars will prevent many accidents, thereby saving lives. The cars will be equipped with a variety of sensors that very accurately detect cars and other obstacles in their path, and they will have automatic programs that control braking and turning to avoid collisions. Given the hundreds of accidents that occur on highways daily, it is clear that humans do a poor job of avoiding accidents and that computer control would be a great improvement.
Second, with the wide use of smart cars, traffic problems will practically disappear. These computer-controlled cars can follow each other closely, even at high speeds. This ability will result in increased highway speeds. Today commuting by car can take hours a day. So the increased speed of smart cars will be a great benefit, welcomed by the many people who commute by car.
Finally, smart cars will bring a reduction in the costs of driving. Because smart cars are programmed to drive the most direct routes, car owners will have to spend less money on repairs and replacement parts. Expensive items such as brakes, tires, and transmissions will last much longer in smart cars than in other cars.
The lecturer challenges the topic proposed in the reading that smart cars promise to make driving safer, quicker and less expensive. And she thinks that it is not clear that smart cars would produce benefits predicted.
First, the article suggests that smart cars will prevent many accidents, thereby saving lives. However, the professor points out that there are still some accidents among smart cars when smart cars fail occasionally. there are more accidents involving much more drivers which brings more severe problems than mechanical cars.
Second, the essay supposes that traffic problems will practically disappear with the wide use of smart cars. But the lecturer supports that more people would like to drive because of the convenience of the smart cars. Then the increased number of drivers in the smart cars would not reduce the commuting time in that traffic jams does not allow drivers to take advantages of high speed of smart cars.
Third, the passage indicates that smart cars will bring a reduction in the costs of driving. Nevertheless, the professor argues that smart cars need to be very expensive to achieve global position. Plus, smart cars also have costly technologies such as sensors to detect how far between the smart car and the car in front of itself. Moreover, some repairs and replacement parts are also expensive so there are much more expenses for smart cars than mechanical cars.
