Automobiles are vehicles that carry people and things on land. Cars are the most common kind of automobile, but there are also trucks, buses, limousines and even bicycles. The kind of automobile that you drive depends on what kind of transportation you need.
In the United States, people drive automobiles more than three trillion miles (five trillion kilometres) each year. Many of these automobiles are gasoline-powered, but some use other fuels. Some of them are powered by wood gas, while others run on a mixture of gasoline and ethanol. Some are even designed to run on more than one type of fuel, but this is rare.
Having a car means that you can go where you want to go whenever you want, without having to rely on other people or public transportation. It gives you the freedom to visit places of interest, travel for business and meet up with friends and family. Having a car also allows you to save time, by not having to wait for your next bus or train.
Cars have become a key part of the modern world. They are used to transport people and goods in urban areas, rural areas and even in remote locations where there is no other transportation. Despite these advantages, many people have limited access to them. The number of cars is rapidly increasing, especially in developing countries. Automobiles are often designed to suit particular needs, such as off-road capability, passenger comfort and high-speed performance.
