I've been watching Formula One long enough to know that teams experience highs and lows as seasons pass. It's just like looking at a sine wave, there are good years, there are bad years. Back in 2007 and 2008 they were the car to beat, and right now, they just aren't on top. And for a team to climb back into contention, breaking agreements and making enemies of everyone in a knee-jerk reaction to the present problems won't solve anything.
Both KERS and the F-duct are (potential) performance improvers that can be applied to everyone. Once implimented and mature, these systems would confer similar levels of preformance improvement to everyone. It's only when the other teams don't have anything yet do the innovators prosper. McLaren enjoyed a performance advantage for the F-duct only at the start of the season, today everyone either have it, or don't based on trials and studies. Time has leveled the playing field.
The same goes with KERS. Yes, McLaren did enjoy an advantage in 2009 and would have looked very good in 2010. But don't think that the other teams were that far behind. Trust me, give an enginner one year of full-out field use and the next generation will be much improved. And do not disregard the fact that Kimi won at Spa last year with t he help of KERS.
In summation, adpotion of KERS and F-duct allows everyone the same level of performance increase, but forces everyone to spend more money.
The Formula One Team's Association is just that, an association that speaks for the common interests of the teams. Maybe today they appear to be useless, but FOTA does serve a purpose. So what if Mclaren go along with the agreement against KERS and the F-duct, it really didn't hurt McLaren. There's much more important issues at stake, such as allowing the big teams to maintain their huge budgets, despite pressure from the FIA to reduce costs. And trust me, FOTA is one mechanism teams such as McLaren and Ferrari use to their advantage.
FOTA should have acted in defence of Schumacher's penalty? I disagree, because FOTA is there for the teams, not drivers. In the case of the penalty, Mercedes did appeal, because they were the ones to speak up for their driver. As well, the driver's association is there for the drivers, although it's mainly for safety issues.
Relax, chill, don't get all excited and angry because McLaren aren't on top today. Just tacking on a couple of go-fast parts (that everyone else can also impliment) won't make things better.
