It's just all this circular argumentation on hand saying that it can't-can't-can't, and one on the other hand saying: "We have not seen enough evidence to prove it either way."
It is, hence it wont go much if any faster when independantly tested
That's not a logical argument. It's like saying "it's amazing that they got a man into space.", then concluding from this that we'd never get to the moon.
So... if 240 mph is shtongkingly and unbelievably fast for a 2 ton supercar, then it can't go any faster? The nice thing about having a ton of development money is that you can always go faster than the guy who built his car last year, or the year before that, or...
A lot of us were Veyron doubters when it was in development, simply because we couldn't see the point of it... but to deny that it can go fast when it obviously can is another thing altogether... some of us learned quite a bit of humility from that, and it's something you should think about.
Like I've said several times before, none of us have claimed that Nissan's claimed time is gospel... (except, in the last few pages,
Prosthetic, who probably needs to learn that the R34 actually makes somewhere between 340-400hp based on who you believe...) We're saying: 7:38, pre-production, inconclusive, but indicative... 7:50, partially wet, November... indicative, but probably nowhere near the best the car can do....
Whereas some people have gone "dah-dah-dah... tires... dah-dah-dah... weight... dah-dah-dah..." it's repetitive... it's boring.
Come April, when the car fails to do any better than 7:45, then you can crow about it. Till then, there's really not much to say about the issue except for some independent crews to get it together with a Turbo on a random racetrack and wring the hell out of it.
So far, the reviews I'm reading are impressive... and some of them are shocked at how nimble the car is despite its weight. Worst thing I've seen is an item on cooked brakes at the track...
