Although the foundation to the modern car year was laid in 1886 by German inventor Karl Benz, Cars did not become widely available until the early 20th century. Henry Ford innovated mass-production techniques that became standard, with Ford, General Motors, and Chrysler. However, he certainly wasn't the only person to develop the horseless carriage.
The history of the automobile reflects a worldwide evolution. Dozens of spin-off industries blossomed creating thousands of new jobs. Oil and steel became two well-established industries.
Vehicle production and sales are one of the major indicators of economic status. Moreover, it influenced the technological advances in petroleum refining, steel making, paint and plate-glass manufacturing, and other industrial processes.
