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.

Summarize the main points made in the lecture, being sure to explain how they challenge the specific points made in the reading passage.
In the passage, the author states the advantages of driverless cars over self driving cars. He states that the technology is simple to understand and will have a positive impact on the driving experience of people. The professor mainly disagrees with the idea put forth by the author and provides valid rebuttals to the reasons provided. The professor's argument is as follows.
Firstly, the author states that autonomous cars are more safer as they cannot cause human error and thus prevent traffic accidents. He also gives an example of a driverless car which has driven over 700,000 miles without a single accident to assert his point. However, the professor points out that driverless cars are actually designed by humans and thus any guidance system used in these cars are prone to the same error as regular traffic accidents. He also states that the car mentioned by the author actually hit another car in the past week and thus questions whether driverless cars are really more safer than self driving cars.
Furthermore, the professor states that with the coming of autonomous cars, the driving license would become a thing of the past as people would not be required to drive. Thus, the age limits are no longer in the picture and more and more people would start using cars for transportation and thus would end up causing an increase in pollution. This directly contradicts the author's argument that driverless cars will be good for the environment as they will drive more efficiently and reduce traffic problems.
Finally, the author states that autonomous cars will give people more time to read or catch up on work as they will be free of daily driving time of approximately one hour. While the professor agrees that these cars provide more free time, he questions the need for it. The professor states that most people consider driving relaxing and enjoy doing so while listening to music or radio. With this extra time, the people would go back to read, watch videos or work which is how they spend their regular time in the days anyway.
