These days, if you pick up a newspaper or turn on the TV or radio, you may hear or read about the advantages of driverless cars, also called self-driving or autonomous cars. The technology is simple to understand: using sensors and computers, these cars can drive without input from a human. This might sound like science fiction, but such vehicles are already on our roads and they will have a positive impact on our driving experience.
Traffic accidents are a leading cause of injuries and fatalities in the United States, and studies show that most crashes are caused by human error. The software that runs driverless cars is not capable of making mistakes. As a result, such vehicles will be much safer. One technology company has a self-driving car that has driven for over 700,000 miles – over one million kilometers – without an accident: a better record than all but the best human drivers.
In addition, self-driving vehicles are good for the environment because they drive more efficiently. On a typical journey within a city, drivers deal with urban traffic by stopping and starting their engines repeatedly. This type of driving means engines work less efficiently and this causes a lot of pollution. Driverless cars, on the other hand, can communicate with other vehicles, which will reduce traffic problems. Autonomous cars will be able to start and stop their engines less often and travel at higher speeds.
Finally, autonomous cars will give passengers time. Instead of having to focus on driving, human occupants can focus on other things. The average time for commuting to and from work in the United States is about thirty minutes each way. Instead of using this time to focus on the road, passengers in driverless cars can read, watch videos, or catch up on work.
In the passage, it is stated that, self-driving cars can put a positive impact in our life. Self-driving cars are safer, good for environment and can save passengers' time. However, the lecturer rule out those points by stating their limitations and counter-examples.
To begin, in the passage, we can see that self-driving or autonomous cars are safer than human drivers because machines are not prone to error like human beings. The idea is supported by the fact that, a self-driving car of a company has travelled about 70,000 miles without any accident. But the lecturer said that as algorithms of self-driving cars are written by humans, there will never be 100 percent possibilty of zero accidents. In fact, the example of the car mentioned previously, has been in an accident with another car. So, according to the lecturer, it cannot be guaranteed that self-driving cars are safer than human drivers.
Secondly, it is stated in the passage that self-driving cars are efficient and good for environment, as it will be driven by a computer program rather than human drivers. But the lecturer denied the fact by stating that if self-driving cars are brought to the market, more people will buy car which can increase the pollution created by cars. Moreover, as there is no driver license needed for such cars, there are no age restrictions for that type of cars. So more people will buy those cars and hence there will be increase in pollution created by increased cars. Hence the lecturer disagrees to that fact of passage because of this reason.
Thirdly, in the passage, self-driving cars are supported by the fact that, they will save passengers' time. Although the lecturer agrees to the argument to some extent, he stated that, as the saved time due to the passengers not having to drive the car by themselves, that time will be a part of daily routine instead. So it is less likely that that time will be used productively, rather it is possible that the increased time will not produce any significant change in the daily life. Thus, the lecturer does not agree to this fact presented in the paragraph.
In conclusion, it can be seen that, the lecturer disagrees with the fact presented in the passage that, self-driving cars will be more useful for daily lige. He ruled out the argument by showing some counter exanples
