UNIT 2
Automobiles changed the world during the 20th century, particularly in the United States and other industrialized nations. They are indeed of great use to us, but they have brought some hazards as well, such as noise and air pollution, and highway fatalities. It is reported that automobile accidents rank among the leading causes of death and injury throughout the world. Fortunately modern innovators are reinventing the automobile. New propulsion systems, fuels, designs, and means of manufacturing cars have all developed rapidly in the past decade.
For example, by using the satellite-aided global positioning system (GPS), a computer in the automobile can locate the vehicle's precise position, and with the application of sensors, smart cars can eliminate most car accidents.
