Spotting hookers in France can be pretty difficult. Not only do many of them use their cars and vans for their private prostitution business (a practice that is called “BMC” in French). In some bigger cities there is also a tendency to wait at bus stops for Johns to pick the prostitutes up. Granted, many bigger venues have high traffic and not much space for cars to stop and pick up a street prostitute. I would not want to be a bus driver in Lille, though (because they need to make extra stops without the prostitutes getting into the bus).
