someone may argue that the "realistic excuse" it's really poor since real underground races uses nos...i know you are going to say "but it's illegal!"...legal, or not legal it is REAL! moreover about "underground/ricer races": some are illegal, but also many are legal and preformed on real tracks; years ago vallelunga circuit was opened by the loca authority at friday night for "ricer" races.
i do not understand why some guys get angry at some requests, even if and when nos will be implemented, no one forces you to join nos-enabled races.
again about the "realistic" thing: the way lfs races works it's just like ricer races! ...indeed, few people meet in some places where they know there will be others willing to race, they may even talk a bit before and when they are enough they vote for race-start...there is no official competition or title, there is not even spectators so...please, don't say "it's unrealistic" unless you want to admit publicly you are a liar...guess what? nos requests arises from the fact nos addicted car really exists...they not come from comics!
of course you may say "i don't like nos!" and that's a legitimate, honest and respectable opinion.
i'm not whishing for nos so strongly, but if it will implemented, i will enjoy it! back in the S1 days, there was a NOS mod (so unfortunate few people used it to cheat online) and it was fun even if it was totally unrealistic and available only on demo cars...take it easy guys!
