Stop letting the top teams rule everything over fear. Make the rules, push them through. Let Mercedes & co huff and puff, see who actually leaves. If one of them does so ****ing be it. Simplify aero, to the point that employing an entire towns worth is gaining you nothing but large wage bills Simplify the engine based on the current unit without all the hybrid crap. Install 2 conventional turbos. Set materials, weight, dimensions and so on. Set a reasonable price per engine. Turbos are 5K a piece at worst so free use There we go, cost reduced to the point small teams don't have to hope they can finish another season, likelyhood of a team gaining a huge advantage by simply employing thousands of people so they can work on several cars for different seasons at once is made much smaller. Mercedes, renault and Honda leave? A cosworth, Judd can build engines, supply teams without engines and make a bit of money from it. Problem solved. Call a few big teams bluff. I know for a fact Red Bull won't leave. F1 will be a money making exercise for them. Ferrari won't leave. Same. Mercedes/Renault could perhaps. Honda could stop supplying and engine. Big deal. Others will replace them. A formula where there's actual racing and sustainability? Why not. And in 5 years time we'll move to 3.5 liter V12s. NA.
