I really do feel that the cost cap is a good idea, but they need to be flexible to make sure they're not just locking successful teams into a successful mode and weaker teams into a weak mode. Even the whole 'good teams' don't get as much wind tunnel and CFD time... basically preventing someone from using their most expensive tool frees funds for all kinds of other things. I'd hate for teams to have 'standard facilities', but if they want things to be equal, it might be worth discussing what baseline each team should be allowed so they can be competitive.
The tire blankets seems like such a weird thing. I get that it feels like an easy way to cut costs, but like any project where the people have no idea what they're talking about are making the decisions, it doesn't sound like it's going to work. I'm sure that Pirelli (or whichever supplier) could create tires that don't require warming, but to simply remove warmers from tires that do require it sounds like a terrible idea. F1 has many forces at work, but both safety and 'the show' need to come before cost cutting.
I miss the days of unlimited engine development. With cost caps in place, unfreeze the engines, if Alpine wants to spend all their money on engine development instead of shrimp cups for VIPs, they why not? I don't really like the engines being a single spec, but I would like for them to be 'interchangeable'. Make the block standard dimensions so you could plop a Ferrari in the back of a Red Bull at a moment's notice. This allows customer teams to design their cars without worrying about the whims of a constructor making a stress bearing power unit specifically suit their own car.
Personally, I'm not opposed to the sprint races. I don't feel like they've been integrated into the race weekend/season very well, and maybe there is no 'right' way to do it. All the same, I don't mind them trying it out, and hope they get it sorted.
