Automobiles are one of the most common forms of transportation in modern society. These vehicles, which are also known as cars, are driven by humans and use a fossil fuel to power the engine.
There are an estimated 1.4 billion cars in operation worldwide. They cover a total of more than three trillion miles each year. The automobile is an icon of American culture, from the Model T Fords that rolled off the assembly line in the early 1900s to the artful mid-century modern designs that cruised U.S. highways and byways in the 1950s. The invention of the automobile revolutionized everyday life in America. It gave people more personal freedom, allowed them to work and live farther away from home, and opened up new industries and social circles.
The development of the automobile was led by a number of pioneers. A French Jesuit priest named Ferdinand Verbiest is thought to have built the first self-propelled vehicle in 1672. In the late 18th century, German inventors Gottlieb Daimler and Wilhelm Maybach designed engines that could be fitted into carriages.
Both men developed prototypes in the 1800s, but neither car was manufactured in large numbers until after the Civil War. The United States’ vast land area, lack of tariff barriers between states, and cheap raw materials encouraged the development of the automobile.
During the first decades of the 20th century, the average income in the United States increased, and more and more families could afford to buy their own automobiles. The advent of the Model T and the assembly line made the automobile affordable for the middle class.
The automobile was a major force behind the growth of the United States as an industrial giant. It helped create and grow numerous industries, including the manufacture of automobile parts and components, such as rubber and plastics, and services like gas stations and convenience stores. It also created a more flexible workforce and changed the way that families and friends gathered.
Many of the same factors that affected the rise of the automobile in the United States also helped it evolve and expand internationally. Countries with limited resources and a need to develop their own transportation systems saw the potential of this useful invention. European designers began to look at the possibilities of the automobile, and soon, they were catching up with American design.
Most automobiles use an internal combustion engine to work. The fuel, which is usually gasoline, diesel fuel, or kerosene, is burned in the engine. This burnt fuel then drives a piston down, which in turn turns the wheels on the vehicle. Several other parts help make the automobile run, such as the transmission system, which is used to change gears to control how fast the car goes. In addition, there are safety features that are designed into most cars to help protect the driver and passengers. Some of these include seat belts, airbags, and crash testing. These safety features have contributed to a lower death rate in accidents caused by automobiles than would otherwise be the case.
