During the 1920s, the automobile began gaining the role as transportation provider in land-use design. By the 1930s, trains and streetcars lost the title as leader in land-use design. Automobiles became an identity of fashion status. The Car Culture had been created.
Yet, unbeknownst to those who created and used the cars, it was totally unsustainable. Since transportation is the foundation to urban growth, it created a problematic scenario for Western Society expansion.
With the increase in global population, for the past 50 to 70 years, history shows that the concentration of inefficient transportation exacerbates the proliferation of unsustainability.
