Hoover this!

I've been assured (by an instructor) that Paris used to be knee deep in dog-shit (although I don't recall a problem on my last visit) just as reputed, and the problem became ridiculous in the 90s. It's really cleaned up now thanks to a penalty system (135E) that was instituted after the previous solution was laughed off the streets. The city had a fleet of two-wheeled vehicles with huge vacuum bags that would drive around sucking up the offending crap. They entered the french lexicon as "merde-mobiles."
