Okay, so it takes 40 minutes PER POINT to get 10cm accuracy. Lets assume they took one point per meter, across three parts of the track (two edges and the centreline). Nordschliefe is something like 20.8km long, so there would be 6114000 points. Assuming, again, that 50 people did it at once, and that it took a negligable time to get from one point to the next, it would take over 9 years of CONTINUOUS AND UNINTERRUPTED 24hr PER DAY, 7 DAYS PER WEEK WORK to get the Nurburgring to that accuracy.
Thus Sony/Polypony are either liars, fools, or just plain wrong.
If a track is accurate in ANY GAME/SIM so far to within 1m in any dimension I will be seriously impressed!!!!
