Check this video of Niki Lauda out where he says that todays F1 cars may aswell be F3 cars, which is why F3 drivers find it so easy to move to F1. He wants F1 to change and to see more aggressive cars with fat tyres and huge wings. I agree, I prefer the days when manufactures were basically able to build what they wanted, to push the engineering limits and then find someone crazy enough to drive it around the track.
