This is definitely not
Germany has blue traffic signs on the Autobahn, not green.
Note the van having a CH plate, must be switzerland.
I have never seen such speed traps here.
Text says they are beeing tested near Ulm in Germany, we'll have to see...
I would be more afraid of the latest laws on distance violations in Germany. A few meters under mandatory distance (half of the current speed in meters) will be very expensive or even cost your license!
