The infamous Tallmadge Circle has cars and trucks traveling around it daily at speeds exceeding the arm-swing of a shotput thrower.
As a result, cars and trucks wanting to enter the circle from its eight connecting streets cannot until one, or sometimes two, of these speeders slow to exit the circle on the connecting street which vehicles are waiting to enter from.
This produces long lines of waiting cars and trucks at each of the connecting streets or, in other words, traffic congestion.
So then, as you would expect, once the waiting vehicles, after a long wait, are able to accelerate into the circle, they speed rapidly around it in order to make up for the time they lost waiting and become the speeders causing the traffic congestion.
It logically follows that if all drivers entering the circle would treat it as one lane, drive slowly around it and allow the first entering vehicle -- at each connecting street they intend to pass -- to merge onto the circle in front of them; then there would be no long lines or traffic congestion and everyone would get where they are going sooner and safer.
