OR....So not only were they in breach, they were gladly going to carry on spending.
What was significant about Singapore regarding putting the brakes on? All I recall was that that's when the other teams made noise, but clearly there was something else happening in the background.
And I might be wrong....
When Red Bull first got word that they may be in trouble, the immediately went into protection mode for their 2022 cap to make sure they did not go over - possibly a kneejerk protection reaction? Not sure how you can deduce that they had an intention to overspend in 2022? If you get caught speeding while on a car journey, human nature is to be overly restrictive of your speed for the rest of the journey to make sure you don't get caught again.
Let's remember that the FIA's investigation results quite clearly stated that Red Bull's 2021 overspend was in no way malicious or intentional. That's the ruling and that's what we must all accept, no matter what your/my/our opinion on the FIA is.
