I was referring to professionalism of the operations and on track action. All that extra money in the big teams can only be used to minimise risk because they can't spend it on an extra race. So they have to spend it over analysing and over preparing everything with ever diminishing returns on investment. Homolgation and detailed regs were meant to allow teams to acknowledge those diminishing returns, for instance "lets not waste money on ever thinner valves stems, lets say 5mm will do".
Unfortunately the political maneuvering with the regs leads to teams tying themselves in knots trying to secure advantages/loopholes for themselves, while trying block others. To stretch the hen house metaphor:
- All teams - Lets fix the hen house floor with the intention that everyone uses the front door.
- Team A - Lets nail it shut (they want to make sure because they know they're not very good at exploiting floor vulnerabilities)
- Team B - We should properly bolt it shut (because crow bars are banned, but they have a spanner that can undo bolts)
- All - Agreed
Team B turns up in Jerez with DDD/Fduct/EBD/split turbo etc. The other teams have optimsed their designs to death so they have no room to manourvre in their designs. Adapting to the new feature requires significant redesign because everything has been squeezed to the limt, everything is so interconnected. Changing to split turbo changs the packaging, and thet requires a complete redesign of the car aerodynamics from tip to tail.
So the engine freeze may be portrayed as the bogeyman, but in reality the non-Merc can't bolt on a split turbo as an aftert thought, their cars need a complete redesign. That is where the costs go through the roof as the resulting arms race gathers pace.
