Unlike a motorbike, automobiles are vehicles that have four wheels and are designed to carry passengers. They are the most commonly used form of transport in the world. They were invented in the late nineteenth century and have greatly affected the society around them.
The first cars were simple steam powered contraptions. They did not have seat belts or turn signals. They were also crude. However, they were still a great improvement over the bicycle.
In the United States, the demand for cars was driven by economic development and higher per capita income. More people had access to jobs and more free time.
The American manufacturing tradition made automobiles inexpensive for middle class families. The invention of the assembly line in 1913 by Henry Ford led to increased production. The car industry became more competitive as automakers began to produce more models.
The American automobile industry rebounded after World War II. By the late 2010s, Tesla became the most valuable automaker in the world. It produced over half a million cars in 2020.
As the demand for vehicles increased, automobile services sprang up. These services met the demand for fuel and parts.
While the automobile changed the way we see transportation, it has also caused many problems. In large cities, the exhaust fumes from automobiles are responsible for smog and air pollution. The depletion of fossil fuels has also contributed to climate change.
In the early twentieth century, the United States saw a rise in the middle class. More people were able to afford an automobile, which helped lead to better roads and paved highways.
