It is now hard to believe that for nearly three decades into the twentieth century, horses or horse-driven stagecoaches were still the personal modes of transport for many Americans in big cities. The building of the Interstate Highway System by the Dwight Eisenhower administration and the emergence of the American suburbs in the 1960s changed the dynamics of car travel. The advantages of having a car in the vast, sprawling, continental landmass of the United States are many.
Americans frequently cross state lines in their cars for work purposes. This mode of transport does away with the hassles of having to book tickets for airplane, train or bus travel.
