I believe this has more to do with radars. France regs have changed a while ago and you can no longer show them precisely on the map, instead you may display a 'zone' that spans across a couple miles where one is present (they're not necessarily average speed ones, still a spot flash).
Essentially this add the radars map to France like we already have here.
My wife had a Peugeot about 10 years ago with something like this. French law made it illegal to use radar detectors or maps showing speed camera locations. The way round it was to show areas where extra care is needed - can't remember exactly what terminology they used.
