Automobiles are the dominant means of transportation in modern civilization. They provide people with a great deal of freedom and offer the ability to go places much more quickly than could be done in a horse drawn carriage. However, automobiles can also cause traffic congestion and are a major source of air pollution. Fortunately, there are other ways to get where you want to go, such as buses, trains and trams.
It is hard to imagine a world without cars. There are more than 1.4 billion cars in operation today. Some of these are passenger cars while others are trucks, motorcycles and SUVs. Some of them are electric and some use natural gas. The internal combustion engine is the most common form of power for automobiles. It uses gasoline, diesel or kerosene to create the force that turns the wheels of the car. This is achieved by burning the fuel in a small engine cylinder that is attached to a crankshaft. The crankshaft pushes the piston, which then moves the wheels of the car.
Exactly who invented the automobile is a matter of debate. It was probably perfected in Germany and France toward the end of the nineteenth century by such men as Gottlieb Daimler, Karl Benz, Nicolaus Otto and Emile Levassor. However, it was Henry Ford that introduced modern mass production techniques to the automotive industry. By building the Model T, he reduced the price of cars to levels affordable to middle class families.
The American version of the automobile has changed society in many ways. In the early years of the twentieth century it was a driving force for progressive change in American culture. The automobile provided women with more freedom and a way to travel, especially for work. This was especially important for women during a time when they were not yet given the right to vote in America. Women drove around with “votes for women” banners and even gave speeches from their automobiles.
In addition, the automobile was a key element of an economy that became increasingly consumer goods oriented. The automobile allowed Americans to shop for their food, clothing and household items while enjoying the convenience of traveling by road. This trend continues today as the automobile is becoming less of a force for change and more of a mode of transport.
There are still some good reasons to have an automobile, particularly in urban areas where public transportation is often unavailable. Automobiles allow people to go shopping, run errands and visit friends in other cities without having to wait for a bus or train. They also are important during emergencies. When a child is sick or someone gets into trouble, the ability to speedily reach your destination can be critical. That is why all vehicles are required by law to be equipped with some kind of safety system, such as a seat belt or air bags. Many cars are also equipped with technology that can help drivers avoid crashes and keep their vehicles in top condition.
