I think that if the cars are running the KERS system, and not 2008 aero updates, then their mileage should not count towards the season Km limit.
If we have the 5 way title fight go down to the last few races, that is going to hobble the top 3 teams in terms of preparing new technology for next year, while fighting for the title this year. That means that the 2 losing teams of the top 3 in the fight will lose the championship this year, and be way behind next year.
Any and all discussion is welcome!
