Automobiles are wheeled passenger vehicles that carries its own motor, typically powered by internal combustion of a volatile fuel. During the late 1800s and the early 1900s the automobile transformed American society. It spawned many new industries and services, such as hotels, restaurants, amusement parks, and fast-food chains. The automobile also opened up the countryside to suburban dwellers, and allowed people living in urban areas to visit rural areas. It became a vital force for economic change in America, transforming the economy from one that was based on manufacturing goods to a consumer goods-oriented society. It ranked as the number one source of jobs by the 1920s, and became a global industry.
Thousands of individual parts make up the modern automobile. Like the human body, it has several semi-independent systems: one for cooling and lubrication, another for electrical power, a heart-like engine that uses pistons to move fuel and air through cylinders, tubes that transport the air and fuel, and wheels and tires to propel the automobile.
The biggest advantage of a car is independence and freedom. You can travel whenever you want, without worrying about missing your bus or train. You can get to places that are not easily reached by other means, such as mountainous areas or deserts. You can reach work and home with ease, and have greater flexibility in arranging your schedule. You can also take trips to far away cities with ease, and have more options for where you want to live in relation to your job.
