I just hope that if Pirelli do stay in F1, they make tyres to a different specification like Bridgestones. They should at least make the tyres work well for the whole grid, rather than who just managed to have setup that gets tyres at correct temperature for car. The way they have made the tyres, it is always going to be main point in performance doing a race as they vary depending on weather. They should have a more neutral impact but the way they make it out, the teams should somehow figure a way to make the tyres work optimally when there is really little they can do but make the cars slower and have a wider operating window. Good for smaller teams though. Also you would think soon weather will have to be designed for these Pirelli tyres by Bernie as it can't be too cold or too hot. Tyres are not good enough level to work on relatively normal temperatures but is blamed on weather by Pirelli not being ideal .
They have been quite lucky given the regulations have promoted competitive overtaking such as Kers and DRS and less downforce. If Bridgestone stayed for 2011 season season at least, and Pirelli came in afterwards, they would most likely look more embarrassing than it is currently. In my opnion, these tyres are anti-racing as quite a few here have also said. They create a lot of marbles which doesn't help racing, tyres degrade too much to be able to follow cars as well as they might be able to do with better tyres, drivers drive well below their limit, mentally and physically. The kind of overtaking Pirelli promotes is drivers letting each other overtake in a gentleman kind of manner due to worry about tyre wear, or helplessness when tyres get worn too much. The good overtakes in my opinion is only when tyres are still fresh and cars are sometimes on limit of braking with Kers and/or DRS helping cars to get wheel to wheel. Even backmarkers helping also.
The problem with this argument is that we have direct quotes from Whitmarsh from more than one year and most recently a few months ago (IIRC some of those quotes made when he was not only McLaren TP put also FOTA chairman, though I don't think the quotes made clear in which role he was speaking) asking specifically for tyres that give teams a "headache" or "make us scratch our heads", or something to that effect. I am tired of posting these quotes, I did so many times, probably earlier in this thread and in the other redundant Pirelli threads.
