I essentially advocate for the race distance tire of 2005. Less marbles off line too. I think banning tire changes and refueling at the same stop would be best. If you must stop due to a flat spotted tire or a puncture, then you can't refuel. That is it. Each team should also submit their first pit stop window of two laps where they would not get penalized if the safety car comes out. After their first stop they have to submit a two lap window for their second pit stop etc. This could also be used to prevent a car from running out of gas if they had a puncture just as the tanks got low. They could only change the affected tire. Flat spotted tires could not be changed at a scheduled fuel stop no matter what. This would effectively give drivers the penalty of an extra stop if they destroy their tires.
They should employ my "pit stop window" submission idea ASAP to exempt those who need fuel during safety car periods. Those whose announced stops occur during the safety car should be the ONLY ones to pit during the safety car period. The pits shouldn't be opened to all.
Nick was robbed at Spain this year and Fernando was robbed at Canada last year and still nothing but talk has been done.
