Automobiles are four-wheeled transportation vehicles that use an engine to create mechanical energy that turns the wheels. They can carry many passengers and travel long distances more quickly than a bus, train or bicycle. Most automobiles are powered by gasoline, but some use electric motors. Whether it is to commute to work, shop or visit friends and family, having a vehicle provides a sense of independence and freedom, not to mention convenience.

The first automobiles were invented in the late 1800s, and they quickly took over the streets and byways of Europe and America. Engineers like Karl Benz perfected the manufacturing process, and American businessman Henry Ford revolutionized the industry by installing assembly lines to increase production and make cars affordable for middle class families. Today, it is nearly impossible to imagine modern life without a car.

DRIVING FORCE

A robust automotive sector is a vital part of the economy. It supports a total of 9.6 million American jobs—about 5 percent of private-sector employment. It is the number one customer of petroleum products, the largest user of steel and a major purchaser of other industrial goods. It is also a key producer of defense-related materials, and it is responsible for a large share of the nation’s transportation infrastructure. During World War II, automobile manufacturers turned out several million military vehicles and supplied other critical war materials with a value of over $30 billion—one-fifth of the nation’s total war production.

DISABILITY

A car can be an invaluable tool for disabled people who need to travel long distances on a regular basis. It can allow them to reach places that would be difficult or impossible to get to by foot, and it can provide them with a level of independence and safety that they may not have had otherwise. The automobile has also enabled disabled individuals to take part in new leisure activities and services, such as motels, hotels, restaurants and amusement parks.

CONVENIENCE

Having a vehicle can save time and effort, which can be especially helpful for people who lead busy lives. Being able to cross town in just minutes can save hours of waiting around for public transportation or visiting friends and family. It can also help to reduce stress by allowing you to set your own schedule and not be dependent on others.

PROS AND CONS

The biggest pro of having a car is the ability to travel long distances quickly and easily. However, there are some drawbacks to owning a car, including the fact that it pollutes the environment. Most cars burn gasoline, which releases carbon dioxide into the atmosphere. This can contribute to climate change, which is harmful to humans and animals. The good news is that there are ways to limit greenhouse emissions from automobiles, such as driving a fuel-efficient vehicle and keeping it maintained properly. These steps can also reduce the amount of money that you spend on gasoline each year. In addition, there are some new technologies being developed that can eventually replace fossil fuels.
