One of the most positive effects of automobiles is that they allow for regular long-distance travel by almost anyone, not just rich people. The mass production of automobiles has led to the development of extensive roadway systems to allow people to visit family and friends in faraway cities as well as commute long distances for jobs. Even traveling short distances is much faster, and people are able to make much better use of time.
Many effects have stemmed from the creation of the automobile, but not all them positive. One of the biggest challenges of the early 21st century is the reliance on nonrenewable fossil fuels in vehicles. Extracting oil from the Earth, as well as burning the refined gasoline for fuel in vehicles, is a major contributor to pollution. This pollution can cause a number of health issues, including emphysema, according to WebMD.
