Thing is I think teams would have already noticed. They're not dumb.
I put F1 somewhere between wrestling and boxing in terms of integrity ... I hold the view that to a large extent they see themselves as "the F1 community" and they are nowhere near being at each other's throats as they like to suggest publicly.... collectively they have all got very rich off this show. Many of them started with not very much. They have more pressure to stick together than to rat each other out - despite what they suggest - IMO.
Cant tell me that they did not all figure out Singapore 08... people on forums figured it out before the end of the race... but which of them said anything?
