It's hard to fathom Red Bull's logic in doing what they've done. Even if they are certain about the fuel flow readings etc, ignoring the technical directive during the race is a bizarre way to start their 2014 campaign.
There are three ways it can go:
1. The FIA agrees with Red Bull and reinstates Ricciardo's P2. All hell breaks loose with the other teams, the whole race result is thrown into disrepute and the season is tainted from the first weekend. Unlikely but possible.
2. Red Bull's flow-rate figures are shown to be wrong. Unlikely.
3. The FIA doesn't agree or disagree with Red Bull's flow-rate figures, but rules against them because they ignored a technical directive, which although isn't law, should have been followed. This one could get messy, but it's the more likely of the three to me.
Either way, Red Bull's decision is a complete PR disaster, coming when their stock amongst fans has never been lower. If they'd followed the directive they would have made 3rd? 4th? Ok not so bad, first race of the season and all that. Worth losing a few points so as not to cause mayhem for the team and possibly everyone else, fans included.
Whichever way it goes they'll come out looking bad - fools.
