During WWII, the United States Office of Price Administration printed a great deal of propaganda meant to encourage the American public to support the war effort by conserving resources. Much of this propaganda centers on the idea that even the smallest failure (not carpooling, for example) directly helps the enemy.

This poster, created in 1943 by Weimer Pursell, depicts a well-to-do man riding in his 1940s convertible alone, save for a ghostly visage of Adolf Hitler riding next to him. The text, "When you ride ALONE you ride with Hitler!" is emblazoned above him, while below reads, "Join a Car-Sharing Club TODAY!" The effect today, in peacetime, is rather amusing.
