I love F1, and try to remain positive as I am a big fan. I have seen many changes over the years but this one I have to say, I can only see as a negative thing. F1 is not just about providing competitive racing to the fans (although that is part of it and they have done a good job on breaking away from the Ferrari dominance culture years where one team strides ahead a bit too much). It's also about teams competing in terms of Technology. F1 has always been about the cutting edge tech and historically should really be about how fast someone can design and race a car around a track. It's a difficult balance to providing entertainment vs Manufacturer competitivity with technological developments.
The problem with the introduction of more and more rules, is that eventually it becomes too bland. There is nowhere left to go. The sport seems to chop and change as it feels like with rules, so companies are not attracted to F1 in fear of their R&D on project X going out the window due to rule changes and a constant moving target. That's why the grid may still stay "small" at 20 or so cars. F1 back in the day used to have nearer 50 cars competing on track it seemed like.
We all accept change to improve the sport, but it used to be exciting and all about new changes to make the cars go faster, but now we have so much standardisation, it feels more like they are trying to make all the cars the same performance wise, to make it more exciting. This works in some series of racing, but not in F1. Give the manufacturers some variable to work with. They have Aerodynamics and that's about it. This is a bad thing. Aero developments only hurt the sport spectating wise, as the dirty air factor becomes even more apparent and the cars rely to heavily on aero for grip.
I would like to see the encouragement of more mechanical grip, and frankly LESS rules generally. It should be more about providing a brief, a problem if you will, and then the manufacturers can solve it with suitable constraints to make the cars similar enough, but to be able to have the freedom to create and to innovate.
Ideal world would be: Make a car with these dimensions and the engine must not output more than XXXc02 levels.
Instead we have: You are making your car engines in this way because we need to cut emissions.
If it's all about being green, there are so many other areas they could save the planet in terms of haulage and transport between events.
The history of big N/A screamers belongs in F1. I could let go if only they would give them the freedom to make something better. Why can't the cars go faster? Why slow them down year upon year? This is F1, not a walk in the park. It's meant to be dangerous. It's meant to be the fastest possible.
