       | four rings with different number of dots around the perimeter.

             | Wait, no, I was working in km instead of m, it's only 54
             | mph. Should be fine.

       | There is an weird tradition of putting random art into the middle
       | of roundabouts in the German speaking world. There is even an
       | Austrian rapper who made a song about an artist unveiling his
       | creation in the middle of a local roundabout [1].

       | If you look for "Kunst im Kreisverkehr" you can find all kinds of
       | weird cases of the years.
