For centuries, land travel was restricted to how fast and far humans or animals could walk. In the 19th century, the invention of the bicycle transferred human energy to a set of wheels.

In the early 20th century, the invention of the automobile forever changed how humans travel, and with the assembly line, Henry Ford forever changed how we manufacture goods.
