What I don't get is this:
They keep saying they are trying to keep the team's costs down, yet they completely change the engine/chassis rules nearly every year making all the teams basically start from scratch. No way can that be saving anyone money.
My guess is that they don't care about the costs, they just keep changing the rules to keep ferrari from completely running away with the R&D and dominating every year like they did for most of the last decade.
