On the way home from dinner and a bit of shopping, Jon and I were going through the traffic circle near our house, and we saw the most stunning example of stupidity I can ever recall seeing.
Someone was trying to make a 3 point turn in the entry port (split by a small triangular cement divider) to turn around. Presumably because he or she felt they were going the wrong way.
Now … stay with me here … he or she is entering a traffic circle … this is a circle … which means it comes right back to where he or she was starting, and conveniently pointed the other way.
So he or she was basically jammed into the entry portal sideways when it would have taken 5 seconds to simply go around the circle …
Duh … :-)
