A motor vehicle with four wheels, usually fueled by gasoline (a liquid petroleum product), intended to transport passengers or goods. Developed in the late 1800s, the modern automobile has become one of the most universal of modern technologies and is manufactured by a world-wide industry.
Automobiles can be used to travel far distances faster and more efficiently than walking or riding a bicycle. However, they also cause air pollution.
Cars are an essential part of the developed world and their use has been increasing worldwide. In the United States, automobiles were introduced in the early 20th century as a way to replace horse-drawn carriages.
Several inventors worked on automobiles over the years, but the first successful motorized vehicle was patented in 1885 by Karl Benz. He and his wife Bertha Benz drove a self-propelled motor vehicle for over 106 km in a single trip in Germany, which became famous and helped advance the technology.
The invention of the automobile changed society and gave people more freedom to do what they wanted when they wanted. For example, it made it possible to go shopping or visit relatives without having to worry about catching the last bus home.
Some places have public transportation such as buses, trains and trams, which can help people travel more quickly and cheaply than by car when traffic jams are a problem. This helps save fuel and cuts down on air pollution. In addition, many people who live in urban areas have access to bikes or scooters which can reduce the number of cars on the road and thus reduce greenhouse gas emissions.
