50 is such a nice round number, I think that's why no more have been added and why there probably won't be any more added either. That is unless some of those tiny little New England states are merged (which I think is a good idea. Many states have counties larger than those.)
It's true that red is always on top, green on the bottom. Seems simple enough, yes. So what happens at night when you can't see what order they are in?
The only thing I'm uncertain of is the shapes they have chosen. As someone said, a triangle is used for yield or caution signs, not stop. Stop signs are hexagons but at night a small lit up hexagon shape could be hard to distinguish from a circle. I believe red should be a square, yellow a triangle and green a circle.
No, the paint would be chipping and flying off, the outer shell would probably have shattered and it most certainly wouldn't continue acting like a water balloon after the initial impact. I call fake.
