So the $7.25m wasn’t right that was reported when this started. How can it go from 7.25 to 1.8. Feels like a bit of negotiation went on there as well.
It was never stated as $7.25M. It was stated that the definition of a "minor breach" of the cost cap was an overspend of up to 5%. So given the cost cap, that is the maximum amount that would be defined in that way. It's only today that the actual amount has been revealed.
As the Constructor's Champion, RBR already has the lowest amount of permitted testing time. There is a sliding scale, designed to advantge the back of the grid with more time to close the gap between the teams. So they now have even less time, which is a serious disadvantage.
The financial penalty is nonsense however, especially it's an actual fine and not a reduction in the cost cap for next season, which I think would have been more appropriate. However, the the FIA wouldn't have got their grubby hands on that money, it just wouldn't have been spent. And then how would they all get their bonuses and pay for their jets?
In the end, these teams have amazing talent solely employed to find and exploit loopholes in the regulations. They are all at it in one way or another.
The FIA are the ones here that are damaging themselves. The teams are doing what it takes to win and compete. The upholding of the appeal by Alpine today is yet another example. They don't know what they are doing, they are not consistently applying their own rules and they are ruining the (outward facing) integrity of the sport. Especially with new audiences who don't understand that bending the rules is how to win.
