It's a weird way to show the quality of a road construction project to the public, but I'm grateful for the video because it shows to the public how narrow a road suffices for an auxiliary runway. The usual videos about exercises on German Autobahnen showed the use of wider roads only.
This doesn't help NATO much, though. NATO is in love with huge airbases only. There doesn't seem to be any interest in using auxiliary airfields, and thus all that attention is being paid to expensive aerial tankers even for missions on NATO's periphery.
