I'm bumping this thread because I found it interesting, and also I was searching for any reason why the graffiti at the Ring is all over the road?
1. Some of the graffiti is obviously advertizements. I've seen Opel, Benz, and others advertized in these virtual chalk drawings.
2. I'm also guessing that perhaps the owners of the 'Ring might not have wanted a bunch of billboards all over the place (like in other GT tracks) when the track is put into videogames, so this was PD's subtle way of introducing ads in a creative, more inconspicuous way.
3. I've never seen any pics online of real-life graffiti and/or ads on the Nurburgring road, but I'm not an expert on the 'Ring's rules, nor have I done an all-out search for Ring/graffiti pics. But wouldn't these drawings lead to small (but potentially dangerous) anomolies on the road's surface that could screw up a car's traction with the high G-forces necessary in some of those corners?
Anyone else wanna shed some light?
