Suggestion: Manufacture cars with two gas tank doors, one on each side of the vehicle.
Description: Cars always have one gas tank door on either left or right hand side of the vehicle. In U. S. gas tank doors are commonly located on the left side, the driver′s side. Feeding from the opposite side is… cumbersome, and this creates the need for two different lines for waiting.
Pros: A dual or duplicated tank door would eliminate the need for two different lines or some drive maneuvering when the shorter line (with tank door on the right in U.S.) is chosen.
Cons: Additional manufacturing cost, decreasing number of gasoline & diesel vehicles in the near future, Idea
Drivers: Car manufacturers
