it was a sunny afternoon in april 2003, i was wearing the new underwear i bought the day before, it fitted perfectly. the pizza i had for lunch was great, cokes tasted good and was ~ 7C° cold. i looked into a pc game mag and saw a small article "geheimtipp" (secret tip?) about lfs. downloaded it, went to mp, annoyed everyone with the question on how to get the gtt "enabled" and loved it since then (had a thrustmaster formula one wheel since 1995 or 1996 for nfs1).
well, autobahns just go straight and that's quite boring on a bike (at least it was for me. could be, because i only had a 600cc suzuki bandit and was missing some speed there :shy
of course going via autobahn is much faster than going abroad, but you are going for fun, right?
except when you want to restart a race only because you got a slight hit and leave the server after shouting "idiot" at the one who caused your crash perhaps, right?
