While I'm sure that Nissan DID in fact perform extensive wind tunnel testing, I don't have access to those results, nor does anyone I know of (with the possible exception of Alan T. HS30-H, which wouldn't surprise me one bit to find out). So I assume that once Bjhines and the guys do their testing, those results and possibly some video of the proceedings will be openly available, declassified for the masses, however you want to put it. At least I hope that to be the case, anyway. As for being harsh, you are free to present your perspective in whatever fashion you choose, though since you and I have neither met in person, nor interacted online prior to this thread that I can recall, I personally prefer to try to make a neutral to positive first impression with my posting if at all possible, and provide links to illuminate where my ideas are coming from...
