Good design should be simple and intentional. Many times, however, it goes unnoticed. For example, the always there, but yet unseen gas gauge that is in every car and truck made today. Look closer though, I am talking about the icon for the gauge.
If I were to show almost anyone other than a young child where that icon is from, they would most likely say it is from a car of some type.

Now here is a question. Which side of the car is a Volkswagon Passat’ gas cap to fill up the car? Left or right? Have you ever driven someone else’s car or a rental and you drive up to the filling station and you realize you are on the wrong side? Why do I ask? Well like I said above, sometimes good design goes unnoticed. Get into your car and look closer at the gas symbol, notice anything else? An arrow? Yes, the often unnoticed arrow that is intentionally there to do one thing—tell you which side of the car your gas cap is on.

Simple, intentional and often unnoticed.

And now you know!
