As I see , Ron Dennis says some interesting things there. The fact that they needed to repeat the race 10 times, to have the Veyron as the winner, is very impressive for the Mclaren!
Through it still doesn't give a clue that the launch control was actually enabled ( He says that "So we had to do that whole thing about ten times before it managed to get off the line cleanly and catch us up. Because every time they dropped the clutch it bogged down and we were gone" and that the entire filming exercise had to be changed ad hoc to make the Veyron look quicker than it actually was, but he doesn't explain how it had to be changed ) . There is still a possibility through ( from what is said in the article) that they finally enabled it but we can't know it for sure and take it as a fact (in my opinion).
Also it doesn't change the fact that the Stig was the driver of the Mclaren ( You can't beat easily a pro like him ).
Still is very impressive for the Mclaren, but again, we must not forget that Veyron is not in the same category with the Mclaren . As I said is a gran tourer and it is a "one of it's kind" car for it's category and a very iconic car overall. Cars closer to Mclaren ( same category -light hypercars ) are cars like Gumpert Apollo sport, Ultima GTR, Pagani zonda Cinque roadster, Koenigsegg CCXR edition, Ultimate aero ( for races like the top gear one in a straight line ) and many more.
As to what is more iconic . When you google Prius iconic maybe it shows thousands hits and articles ( useless scientific fact : prius iconic shows around 734.000 results Veyron iconic shows around 2.970.000 results - i said "useless" because we all know how google shows thousands of results for every search term we put ), but it is because the Prius is part of an entire international campaign to to promote hybrid cars for the masses , so everyone sees countless advertisements for it.
And one question here: So every high performance car , in order to be included in our car games have to be compared first with the Mclaren F1, to be proven worthy to be included in our games? Why cars like the Prius and the i-Miev get a free pass, and are not compared performance-wise with the top-end everyday cars ? If for high performance cars, each of them needed first to be compared with every other high performance car in existence in order to prove "worthy" , then we would have only cars like Pagani Zonda R and Radical in our games, and every other performance car would be out of our games ( including the Mclaren).
As for Gran turismo, of course I know that , they hadn't the time to make all cars they wanted premium. Kaz has stated in an interview that the hadn't the time to make the Veyron and other cars premium. It is still a case of bad time management. I know also that we will have new DLC before christmas, and I am sure that it will not be another RM car pack ( It makes no sense to give us again RM cars ) . I'm sure that pack will have many good surprises for us!
