Atlantian, I'd like to ask you a single question. In fact I would like to direct the question at all the oval bashers.
Lets just totally forget that racing is a spectator sport for a minute. After all we dont play LFS to be spectators, we are here to be drivers, and in some cases support a driver via voice over IP. So the spectator followings don't matter here.
That said the question is quite simple, and I probably already know atlantian's answer. Have you ever experienced (sim racing or otherwise) the tension of being in the middle of a 3 wide situation, where the slightest twitch will take all 3 of you off track, at 170+ mph?
The answer is most likely no, oval bashers have not experienced this. And they aren' willing to, for fear of being proven wrong.
Even in the BMW-Sauber F1.06 the above situtation is truly hair raising, because of just how fast things happen at that speed. You might think that statement is a little obvious, but think about it for a moment. You are mere inches from your opponents, leaving you with less than a rally course's width to race on, in a situtation where you must recognize the fact that while racing these people, you must also cooperate to avoid mutually assured destruction, and if any of the 3 (or 4, ive seen this happen on the Kyoto oval as well) sneezes, twitches, or even shifts your foot on the throttle, it will end the race for all 3 of you.
