I'm mostly interested in the situation in France, but this might be interesting for other countries as well, especially in the context of the current rise of bicycle usage:
Germany has § 27 in its traffic law (StVO), permitting huge groups of cyclists to go through traffic as one single vehicle, even crossing red traffic lights as long as the vehicles at the front passed at green.
Do similar laws (for civil use) exist in France or other countries?
A first look at the French code de la route revealed nothing, and Wikipedia has no translations listed for the German article.
