The four way stop is never executed well with no one seeming to know that if two cars arrive at the same time, the car to the right goes first... There is always. Waving and confusion. Atleast in the round about, it is survival of the fittest.
Where I live, everyone knows how to navigate the four way stop. It’s very civilized. If people have to make eye contact and wave, what’s the harm in that? In a round a bout, the towns usually plant lots of stuff in the middle and the visibility is poor. No one knows how to yield and no one can make eye contact. I would like to see stats on accidents in both contexts.
