Here is a comprehensive summary of the Wikipedia article on cars:

A car, or automobile, is a wheeled motor vehicle primarily designed to transport one to eight people on roads, with over one billion in use worldwide. While early steam-powered and internal combustion vehicles appeared in the late 18th and early 19th centuries, the modern, marketable car was invented by German engineer Carl Benz, who patented his Benz Patent-Motorwagen in 1886. Mass production began in the early 20th century with vehicles like the 1908 Ford Model T, leading to rapid adoption in the US and later, globally after World War II, with usage still increasing significantly in countries like China and India.

Over decades, cars have evolved with numerous features for comfort and convenience, though most in the early 2020s still rely on fossil-fuel-powered internal combustion engines. However, electric cars, which have been available since the 2000s, are gaining prominence as a key solution in climate change mitigation strategies. While cars provide immense benefits such as personal mobility, independence, and economic growth through the automotive industry, they also carry significant societal costs including air pollution, road congestion, and being the leading cause of injury-related deaths worldwide.
