No F1 should be kept roughly as it is but;
Ban carbon Brakes, to increase braking distances
Reduce down force, by limiting wing sizes more.
Bring back wide slicks, to give more mechanical grip.
Ban Traction Control,
Ask Shumi, (Politely) to try his hand at Indi cars.
To standardise things like engines and transmissions is just plain wrong, F1 is meant to be more than just wheel to wheel racing, it's more like a technological 'War' in a peacefull form, it's meant to push the boundaries of technology, it won't if you have to use the same engine as the next team.
IMO of course, .....but I'm right
