What two things contributed the car culture?

* The rise of the suburbs. As people moved out of cities and into the suburbs, they needed a way to get around. The car became the ideal solution, as it allowed people to travel long distances quickly and easily.

* The development of the interstate highway system. The construction of the interstate highway system in the 1950s and 1960s made it even easier for people to travel by car. The highways connected cities and towns across the country, and they made it possible to drive from coast to coast in just a few days.
