When inventors are inventing, they often look forward to see what product could make things easier, cheaper, and make money. They also could benefit from looking backward; Henry Ford’s Model T was a marvel of engineering. It was flexible enough to handle America’s horrid early 1900s roads, strong enough to keep running, and was manufactured using cheaper processes in one-tenth the time. All these changes were revolutionary at the time. But, nearly all modern automobiles are designed and manufactured using the same fundamental processes invented by Ford (though modern roads are much better now).
