I have always thought that a total team cost cap is unenforceable and still do. Some segments might be like PU/transmission supply might be and how much it cost to build a seat but stuff like electronics, software development, aero. etc would be nearly impossible to contain. Does anyone really expect teams who specialise in beating the rule book will not do the same thing to any capping rule if they can. The other thing I can't get my head around is Ferrari opening up the books to any outside auditor, I hope I live long enough when the auditors ask the question.
