At first I was like "a word of caution" because Germany is inbetween governments (even though they will be the same) but seeing that ministers from all three parties involved support it, there might be something in it. On the other hand, the EU as well as the German Bundesverwaltungsgericht are playing hard regarding air quality in cities. The source I've read (http://taz.de/Regierung-erwaegt-kostenlosen-OePNV/!5481464/ http://taz.de/Regierung-erwaegt-kostenlosen-OePNV/!5481464/ ) mentions seven more ideas in the letter to the EU, only the free public transport standing out as radical. Traffic restrictions, incentives for e-mobility and upgrading pollution vehicles are others. I bet that's what is to be expected sooner or later and someone just slipped the radical idea about free public transport in to see the fallout.
