To be honest, I'm tired of seeing Sergio Marchionne complain about Liberty Media's 2021 engine proposal. If he doesn't like the idea of a budget cap, well then so be it. I think teams working within a certain cap will be an amazing sight to see, especially in terms of who's the fastest. If Ferrari leaves, then so be it, keep stepping. PS: Honestly, to make another statement about engine rules, I say they give us a 2.4 litre formula, 10 cylinders, with SOME of the current turbo bullshit (goodbye MGU-H).
