I heard about it on French radio yesterday. Many French "experts" are against the idea, as it would be confused by "incorrect signage".

"If cars were still driving too fast past my cottage, all I would have to do was to put up a homemade sign marked "20" and they would brake rapidly". Total loon.

The "safety expert" just rattled on about drivers being distracted from the road, by having to check for speed limit signs and their speedo.
