Automobiles are self-propelled vehicles used for transportation on land, with four wheels and an internal combustion engine fueled most often by gasoline. The most common use of automobiles is for passenger transport.
The automobile is one of the most universal and influential modern technologies, manufactured by a world-wide industry. In 2017 there were more than 73 million new automobiles built worldwide.
Cars are a popular alternative to public transport, and can be a good way for people to travel around their cities. They also allow people to travel safely and efficiently.
Owning a car can help people make money. Some employers prefer employees who have reliable transportation, and some jobs require a car.
A car can also be a good way to reduce greenhouse gas emissions, which are a major contributor to climate change. However, drivers should be careful to choose fuel-efficient vehicles.
Automakers can also improve their cars by using more efficient engines, fuel systems, and other technologies. These can help them reduce their carbon footprint and keep their operating costs low.
Cars can also be a great way to get from place to place quickly, and can save people time by eliminating the need for taxis or rental cars. They can also help people avoid the cost and hassle of getting dropped off at a train station and walking to their destination.
The first automobile, a three-wheeled car with an engine that drove the rear wheels, was designed by German engineer Karl Benz in 1885. He patented his design in 1886, and other teams began producing similar vehicles almost concurrently.
