You talk as if these are facts.
Well there are some facts:
- teams have agreed on a budget/resource frame and by all published communications intend to keep to it
- resource restrictions in the chassis/racing sector did work to bring the cost down. That is confirmed by all FOTA communications. For top teams RRA has reduced costs by €100-150m.
- the only time in the last 20 years that engine cost have come down was triggered by the engine freeze combined with longevity sporting targets. The cost drop was something like €30m for customer teams and €90m for manufacturers.
- Ferrari and Mercedes publicly declared that they do not want to go back to unlimited spending on engines
I don't think that I need to bring quotations for these facts. People who observe the debate are familiar with those things. If you don't believe me I can make an effort to dig out the documents.
Based on those facts a sensible system of resource restrictions needs to involve the power train from 2014 and it should not increase the costs of manufacturer and customer teams. At least that is the way I see it. If you come to different conclusions we can end the debate here because the basis of discussion doesn't match.
