Har man tillgång till bilspel så kan man ju pausa och titta lite med kamera bilden, förutsatt att det går i spelet. I spelen Forza motorsport 2 och PGR 3 - 4 vet jag att det går.
It is due to motorsport fans leaving messages. A lot of the graffiti is about lap times, when that person took their lap, also in memorial to those who have died there. The Nordschleife is a public road, but is only really used for those wishing to complete a lap.
It IS a regular road when it isn't being used for racing. Probably done by those lucky enough to have had a go. Car manufacturers use the track for testing standard road cars and the like. Possibly test results and braking markers distances etc linked to that Just people wanting to leave their mark on a piece of racing history. good question dont know the answer There are 3 reasons for this: 1)There are some smaller graffiti that was done to leave their mark that they were there 2)Vandals being vandals 3)It does serve as a regular road sometimes, but that could serve as part of 1 or 2
