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.
The reading and the lecture are about the pros and cons of driverless or autonomous cars. The reading claims that they have several benefits such as reducing the number of car accidents, reducing pollution, and taking the painstaking task of driving off commuters' hands. However, the lecture refutes each of these three points for the following reasons.
To begin, the writer claims that driverless cars may help to alleviate the issue of road accidents caused by human errors. She claims that software makes no mistakes and cites the example of one driverless car model that drove a million kilometers without any accident. However, the speaker of the lecture directly refutes this claim by stating that, just last month, the same car crashed into another car. The speaker says that since software is designed by humans themselves, it is bound to have errors.
Secondly, the writer posits that driverless vehicles will lessen the pollution caused by frequent starting and stopping of the engine. While the speaker concedes that this may be true, this benefit might be outweighed by the existence of such a car itself. Since more people may wish to have a driverless car and the criteria for obtaining a driving license may be made more lenient, there may be more and more cars on the road. This may actually exacerbate the problem of vehicular emissions.
Finally, the writer says that not having to drive will free up time for commuters to do other things such as reading, watching videos, or working. The speaker says that this might not be the blessing the writer thinks it to be. Some people find driving relaxing and may not like the idea of having more time to work during the day. Driverless cars might essentially ruin their commuting experience.
To sum up, while the writer makes several good arguments in favor of driverless cars, the speaker believes that these arguments must be examined in further detail before such cars can be hailed as a cure-all for the problems associated with human driving.
