Interestingly no other team had problems keeping under the usage limits using what is supposed to be an homologated piece of tech.
So i'm really not buying that. This in combination with the strange engine problems for Vettel and also their reliability issues, tells me that Red Bull is messing in the grey areas as usual.
I seriously believe that all the troubles facing them are in fact due to Newey and the engineers seriously bending some rules, resulting in the mess they have now.
However, all this comes as a calculated risk, as when they find the undetactable AND reliable ways of breaking the rules (or bending them a lot) they will be fastest again.
Looking back, this is a fine tradition in the sport...
