So far, better than expected. But for me what I feared is not so much what would happen in this first 6 months.
It's a new reg change, the drivers and teams need to adjust. It's spiced things up, it's exciting, it's new and all still have to adjust to things and refine things.
What I have always feared in the longrun, is after a few seasons, F1 will be as dull as ever.. once the teams update the cars, work out all of the bugs, the drivers adapt, and everything becomes "easier".
We saw between Button and Perez for example, they could run a fine line between locking up and going too deep, vs braking too early.. and there was plenty of room for both good moves and also mistakes.
As opposed to the future, when no one will ever make a mistake. When the car is on rails, and is 'too easy'.. and they never run wide or lock the brakes. It has come to this point during last season, and these new regs have to potential to become even worse. Cruising, conserving.. managing.. and then never making mistakes while attacking. Virtually no risk to overtake, rarely reliability problems etc. The exact opposite of why you tune into a race weekend or enjoy "racing".
So far.. so good. Better than expected actually. Even at Monza the other day, many good battles and it's pretty much been like that every race of the season so far. But it's like that new feeling you get when you see a movie you've never seen before or meet someone new. You only get that feeling once. They can't change engine and aero regs every season just to maintain that.. it doesn't work.
So every "regulation cycle" it's good at the start, ok in the middle and starts to get bad at the end. This was the worst part of the last 2 years, not whether or not Redbull or Vettel were winning or not. The cars simply became too easy to drive.
And if you have a sprint formula, that's ok.. because that will just make them push even more. Everyone has to drive that way or get left behind. In the cruising/managing/conserving era.. we need it to be hard to drive. Otherwise it's just a Sunday taxi drive through the mountains. With occasional bursts of actual racing to remind you that it IS actually a race.
