The Golden Rectangle

Artists, I imagine, are quite familiar with the mysteries of---canvas size. What proportions to make the canvas, length and height, etc. Interesting forces come to play, and the easiest way to begin is to think of a portrait proportion as, possibly, different from a landscape proportion. And there you have it. And neither size is the golden rectangle.

What does this have to do with traffic? 99% of drivers drive too fast and 99% of paintings are the wrong size.
