Gas Tank Poka-Yoke
Have you ever been driving a rental car (or a car that you normally don't drive) when you pull into the gas station to fill up only to realize that you don't know which side of the car is the gas tank? In the past, you had a 50/50 chance of getting it right when you pulled up to the pump. After getting out of the car to check, you may have to pull back in on the other side...Definitely muda.
Here is a great example of a simple poka-yoke device that solves this problem. Look on the dashboard at the gas gauge. Most newer cars have added a simple arrow indicating the correct side of the vehicle to fill up the gas tank. Cool poka-yoke device, almost as good as the low gas indicator!
