I overheard French people talking about it on the street of NY, and I found it on likecool.com. The urilift unit (pictured here) can be found in several cities in Europe, it stays underground all day, and comes up at 10pm to go back down at 3pm... They seem to have noticed that this is when the drinking -therefore the toilet need- happens.
But these are for men only as they're actually a set of 3 urinals. The one we could import to the US would be the urigienic, which has a door, and also has the advantage of being unisex thanks to its "revolutionary suspended toilet seat".
