Nope, Those Aren't Mailboxes: Paris Rolls Out Sidewalk Urinals. (NPR, 8/14/2018)
In Paris, authorities are taking an unusual approach to combat the scourge of public urination: Make urination even more public. The city is experimenting with completely exposed, eco-friendly urinals.
The devices are called "Uritrottoir," which combines the words for urinal and pavement. They're not at all subtle.
They're bright red and in heavily trafficked areas — for example, directly next to the Seine near the Notre Dame Cathedral.
