A car is a wheeled, self-powered motor vehicle used for transportation. Most definitions of the term specify that cars are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. Cars are equipped with controls used for driving, parking, and passenger comfort and safety. New controls have also been added to vehicles, making them more complex. Examples include air conditioning, navigation systems, and car entertainment. Most cars in use today are propelled by an internal combustion engine, fueled by deflagration of gasoline (also known as petrol) or diesel. Both fuels cause air pollution and are also blamed for contributing to climate change and global warming.
