Auto are used to transport people and items from one location to another location. After years or various designs, inventors were able to develop a functional general design that is utilized by major automakers as the foundation of their designs. Automobiles generally use gasoline to fuel the internal engine. But technological advances have led to the design of cars that run on electricity and even water. An auto is a car: a vehicle with four wheels and an internal combustion engine. The automobile is one of the most common ways to travel.
Automobiles are just about everywhere: in cities, small towns, and even in rural areas, where it's too far to walk from place to place and there's very little public transportation. Trucks, vans, buses, and limousines are bigger than the typical automobile, but they’re automobiles, too. A motorcycle isn't an automobile because it only has two wheels. Automobiles are good for getting around, but they also cause pollution and automobile accidents.
