Automobiles and Motorcycles


Automobiles are the most popular means of transport for people all over the world. There are 1.4 billion passenger cars on the road today, with one-quarter of those vehicles made in the United States alone. They are also the most common mode of transportation for many Americans, driving three trillion miles annually. Manufacturers are increasing their production rates and introducing new models more frequently. In fact, 70 million new passenger cars are sold around the world each year.

Automobiles are also often referred to as motorcycles. Although motorcycles are three-wheeled and not designed to carry a lot of passengers, they can be classified as automobiles, especially when equipped with sidecars and seats. In addition, motorcycles are easier to tow than cars. A motorcycle requires only a winch to tow, and is much easier to drive than a car.

Automobiles are highly complex systems that contain thousands of parts. The circulatory system of an automobile contains the heart, lungs, and blood, as well as fuel and lubrication oil. The engine is also a complex system, with components such as pistons, cylinders, and fuel delivery tubes. These components are vital to the proper operation of the automobile.

Automobiles are classified according to their size and capabilities. Motorcycles aren’t considered automobiles, because they only carry a small number of passengers. On the other hand, automobiles are vehicles designed to carry a large number of passengers. In several court cases, a motorcycle has been ruled not an automobile.
