we saw this matt on our way to brugge on the motorway, but too late and too much trafic, so I promised myself to take a pictur on the way home, but that was after midnight, with still a lott of traffic and I did not dare to walk to the middle of the E4O, so I parked on the far right and zoomed in, the picture was pure blackness, so I had to fresh it up. Perhaps it does not look like a matt, but it sure is.
