@AR3-GP
You are conflating processes.
As I've said in the GP thread, teams can protest if they provide evidence and a rule contravention, as Red Bull did with DAS. They do not need to provide a working diagram and intimate knowledge of the system.
So the first avenue is available, and many protests go unpublicised.
Secondly, the FIA can check cars without the need for any controversy. Your suggestion that they don't or wont because of controversy is not applicable and without foundation. It happens frequently and without controversy for 99% of cases and 1 example you cite does not equal the rule. I think it prudent for further discussion to accept the FIA are not perfect but also do not have some team led witch-hunt against Red Bull. Otherwise we are just going round in circles.
Thirdly, the random check process is for all teams. Red Bull had their turn in Oz and a couple of items were checked.
In Jeddah, Mercedes, Aston and Red bull all had a bunch of items checked over including front floor deflection, fuel, exhaust and tyre temp, engine oil, rear wings, Torque control etc. In Bahrain, for RB the list includes front wing deflection test both symmetric and asymmetric and then Floor body, Floor fences, Floor edge wing, Nose, Forward chassis, Mirror housing Sidepod, Coke panel, Engine cover, Front wing Profiles
Mercedes had already had a random check for their rear crash structure and rear wing and clutch release (electrics) in Bahrain and were checked again the very following race for a host of other things. Hamilton's car was brought in and they checked:
Floor body, Floor fences, Floor edge wing, Nose, Forward chassis, Mirror housing Sidepod, Coke panel, Engine cover, Front wing Profiles
This is very important now as some facts over the last 3 races:
In the list of 20 items, Red Bull had about 17 listed items none of those being the suspension. So what do you think a governing body would do when Red Bull's number comes up? Check items they already checked at the previous races and leave out the suspension which they haven't checked?
Why would they consciously ignore a part of the car they haven't checked? Because people might suggest that there is some ghosts in the closet or because the FIA is too scared to check because the new story might get out and it will be "controversial"? Because this is the rabbit hole you are heading into that will lead to endless circular arguments.
The facts are that prior to the suspension being checked in the random check...most of the car was checked in the previous 2 races. So no, it's not weird, or extraordinary at all when you view it alongside the facts.
If for every level of what you are claiming you are asking the reader to suspend belief, you are getting further away from objective reduction and into the realms of that what cannot be proven.
When it comes to hypothesis, making the least assumptions is Valhalla. You are making a host of assumptions to back up a claim that is not substantiated anywhere for a simple random check of items the FIA hadn't checked in the previous 2 races. And of course I disagree with your opinion, but I'm glad we could exchange views amicably.
