It’s not a giggling matter if you are a French motorist caught up in an anarchic traffic flow argument between two mayors of adjacent towns, who both think they have sole rights to your right of way.
Both mayors decreed a particular street one-way for traffic, but in opposite directions. The panoply of the French State has had to intervene. The State has designated the flow on the street for two-way traffic!
All’s well that’s ends well……peut etre (Perhaps).
