The automobile industry entered the mainstream in the 1920s. Finally, the average family
 could consider owning a car. Manufacturers had found ways to make cars more efficiently, and safer to drive.
Roads designed for horses were being replaced with roads for cars. Engines were more powerful than ever before, and some interiors were almost as comfortable as home furniture.
Tunnels were being built, gas service stations were popping up left and right.
Owning a car completely changed people’s lives. Suddenly families could travel to the city on the weekend.
A new, mobile society greatly helped the already bustling economy.
