Automobiles are vehicles with four or more wheels that use an internal combustion engine to move. They are used for passenger transportation, cargo transport and special purpose vehicles such as ambulances, fire brigade trucks etc. The automobile has become a central part of modern life. It has opened up the world to people. It enables them to work in different areas and visit friends or family living in other locations. It also allows them to visit places that would be impossible to reach on foot or by public bus. However, it has also resulted in increased environmental pollution and traffic congestion in cities.
The modern automobile was invented in the late 1800s, and it took a few decades for manufacturers to perfect production techniques and establish themselves as market leaders. American Henry Ford introduced mass-production methods with his Model T, and the industry boomed. Dozens of new spin-off industries opened up, such as tire manufacturing, vulcanization and highway construction.
Today automobiles are available in a wide variety of shapes, sizes and colors. They range from small, fuel-efficient models to large and powerful sport utility vehicles. Many cars have air conditioning, stereo systems and other amenities. Some are equipped with 4-wheel drive for off-road driving. These vehicles are often more expensive to buy and operate than standard vehicles, but they can go where other wheeled transport cannot, such as up mountains or on unpaved roads.
One of the main disadvantages to owning an automobile is its maintenance costs. Oil changes, tire replacements and unexpected repairs can add up quickly. Also, the value of a car depreciates over time. Some people have difficulty affording to keep up with car payments and other financial obligations. Lastly, owning an automobile requires that people respect traffic rules and be prepared to deal with the hazards of driving.
