I don't believe the biggest fault is the power units..
It's certainly a huge contributing factor.
For F1 to have genuine relevance, it should maintain some connection to actual cutting edge automotive development and technology..
I don't think that matters because almost all the stuff they have banned are now on road cars. AWD, Traction control, CVT transmissions, anti lock brakes, stability systems........... all of those things were outlawed, so Formula One in a lot of ways isn't even as advanced a your average Nissan Sentra.
I don't understand gut hatred of "hybrids". There are plenty of places to watch big old-fashioned V8s race, including in my personal favorite forms of racing..
I think a lot of people really loved the old high revving F1 V8s, and that's where the hatred is coming from.
I hate the hybrids because they make the cars more complex and expensive. I especially hate them in endurance racing because they are so complex that a privateer team could never run one. If you take a look at Lemans this year, a much, much, much less expensive and less complicated P2 car very nearly stole the show because even Porsche couldn't keep a car together for 24 hours. I believe the only P2 cars that didn't finish were due to accidents. Complicated cars break, and simple ones run like freight trains.
Hybrids are also built on the phony premise they save energy and pollute less, both proven to be lies. For example, it takes more energy to make and dispose of a hybrid battery than it saves over the life of the car, and the same with pollution.
F1 doesn't need to be a nostalgia show to produce decent action..
No, Formula One needs to e real instead of a "spiced up show." That's the main thing.
F1 needs to be fast as hell, which they are getting close to, and they need to be more attractive with less tack on aero pieces. They also need to race well and that gets back to simplier aero rules....... small two element wings and medium sized tunnels
They need to radically rethink the aero and tire regulations.
F1's biggest problem is that it has become phony in order to "spice up the show." I don't even need to go into what's wrong with DRS. We would not even need DRS if the drivers weren't chopping, blocking and swerving all over the road like drunken zombies, but that's another discussion entirely.
In the US, half the telecast is the commentators talking about tires. I know Pirelli has to get their exposure, but come on. It's too damm much. In fact, what exactly does Pirreli get out of it when half the field goes on TV and says things like "the tires were finished after two laps." "we didn't have any grip" "The tires didn't switch on," "the tire performance window is too narrow," and on and on and on. None of that makes me want to go out and buy Pirellis. Conversely, when endurance drivers get out of the car and talk about how they could triple stint their Michelins, that does make me want Michelins instead.
The whole tire thing is phony because in an honest race you would never design a tire to degrade at a certain rate to assure you have pit stops. Instead of making a tire that will go fast for as long as possible, Pirelli is forced to produce a tire that purposely craps out in order to "spice up the show." Since that is apparently less difficult to hit instead of building something that works, every race is all about the shortcomings of the tire.
They need to go back to a tire that will go the distance with a little care. Pit stops are not exciting, no matter how much they try to tell they are. All that can happen in a pitstop is something bad. Unprotected people can get run over, all while the FIA tells us how important safety is. That reason alone is enough to eliminate them, or at least cut down the number of stops. Pit stops also break up the racing. You don't have to pass someone when you can undercut them. I don't believe we have had an on track pass for the lead all year (except maybe Barcelona), and that';s because they don't need to pass each other when they can do it with pit strategy. Now more than ever the race is less in the drivers hands and more in the control of the computers in the pits.
