Driving down the Autobahn somewhere between Celle and Frankfurt, we encountered our first smiley faces along the way.
The first one was to announce construction work being done, slowing down traffic for another 4 km.
The second one announced the end of it. Geschafft = Done with it!
For some reason, these smiley faces do their job. This way, I know some younger people are on the Autobahn force.
