First Roundabout in the Parish

I missed the opening of the 1st roundabout in our parish which is part of a bypass for our parish's main village "Sontheim". When I first came to Germany to live in 1990, there were two roundabouts known to me in Bavaria. One in Munich which was of the variety, those in the roundabout had to give way to those coming in, and the 2nd one was in Lindau on Lake Constance, which worked on the "normal" UK principle, just on the wrong side of the road. Both these roundabouts are well known by my then-colleague Nigel.
Roundabouts have in the meantime become very popular in Germany and but for a few differences on how to signal, they all seem to operate as we know it in the UK.

The bypass reminds me of my holidays in Greece in the 1990s, where big boards proudly announced the huge pointless roadworks in the middle of nowhere were financed by European Union money. Well, we didn't have any boards but there are doubts as to why 3m Euros were spent on a bypass which spared about 12 households the traffic. The next village down the line (in the same parish), has the road going directly through the whole village and effects probably the tenfold of households.

The building emitting large amounts of smoke/steam is another quirk and I suspect also financed with EU money. It's a "green food drying unit", which means farmers cut their grass, deliver it to this building where it is dried & pelleted. The farmer collects it back & feeds his cows with the dried pellets in winter. These units can be found all over Germany. I just can't follow the logic of using tons of oil/gas (some units now use wood/biomass) to fuel these units. Have farmers forgotten how to make hay? Most of these units are placed well away from housing so the heat and steam cannot even be used for heating houses.
I have to admit that one year we used one of these units to process the grass from a field we had just rented. It was full of small bits of barbed wire & the drying process includes the grass passing over a magnetic field which pulls out any metal. We didn't tell the operators what we had in mind & were asked questions when we arrived to pick up the pellets!
