keep in mind that the nürburging u guys talk about so the "Nordschleife" with over 20km distance is nothing else then a PUBLIC ROAD everyone can drive there if they want to...the nordschleife is NO RACE-TRACK since a few years already...so that means that your information is wrong about buying a license...
the only special thing about the nordschleife is that it costs a fee to drive but it is still a PUBLIC ROAD...there are also speed limits on the nordschleife and the police makes controls there because it is not a closed track / racetrack anymore...
but anyway i would love to see the green hell in LFS especialy because "The Mother" is the best track ive ever been driving on
