Yeah I think all the doubters just need to be honest with themselves. The BGP001 is fast, plain and simple, no tricks, no gimmicks. I think it's time that everyone stops talking about BGP's car being underweight, or all that "attracting sponsors" nonsense. I think everyone needs to respect BGP as one of the faster teams. Brawn GP isn't messing around with their limited testing hours, and I expect them to be strong in Melbourne. On the topic of "the doubters just need to be honest with themselves," the same could be said with McLaren's MPslow-Twentyslow. C'mon, just be honest and admit that they'll be slow until they have a major overhaul (could be spain, could be hungary, who knows when it will come). I admit the McLaren reference is off-topic, but in terms of 'doubters' it seemed relevant.
Clarification: I'm not saying BGP will be the fastest team, and I'm not saying McLaren will be the slowest team. 'Doubters' are people who think a) Brawn will end up at the back of the grid, and b) McLaren will be at the front of the grid.
I'm just asking everyone to trust common sense!
