This would be great in those parts of Germany that are road but not Autobahn e.g Bundesstrasse. I had NO idea where the road was in Shleswig Holstein. (Which is flatter then The Netherlands) If there were no other cars, I had my high beams on, but if there were, the sight dropped enopurnously.
Sure there were lights at the crossings on one side, but which side?
Also: do not forget that this is a test. Itis only 500m. They will probably be testing if it sticks to the road or if it is pulled out after a few thousand cars. Also testing if it still works after a year and how well.
