The most obvious change for everyday people was that cars gave them a way to get around quickly. Suddenly, people had a new mode of transportation that could get them more places, which meant leisure travel became something common folk could afford. If you need to travel quite a distance, it allows you to arrive quickly, rested, and neither too hot or too cold. If you need to take along a lot of groceries or equipment, it is a lot easier to do so in a car, rather than pull a wagon.
