Oh I didn't mean to suggest they aren't trying or willing to smash cost. They do have. From 25 to 20, then 15, and 12 MM per unit. Then they hit the "idea-wall", and new research is needed to push this line further. Problem is, if you freeze development, and standardize modules (McLaren will do this or that), Ferrari and Mercedes will not take it sitting down, and the will leave the series.
