The problem is there's way too much money in the sport. With literally billions at stake noone would want to take risks. This is not going to change.
RRA won't help also. Whoever is in control will use it for "divide and conquer" tactics as we see now.
BUT 40 years from now, someone would say, oh, I watched Canadian GP 2011, that was real classic!
Face it, F1 would not change globally in a heartbeat.
I agree on many points but "you don't have to scroll back 40 years to find a Formula 1 with car- and engine-diversity, as well as something technically- and racing-wise xciting" always make me laugh.
I need to look up some aeronautics forums, are there threads "screw Raptor (no pun intended, or just very very little
), now Sopwith and Albatros that's the real engine and airframe-diversity"? Designs do converge to an optimum over time.
I agree there's young driver problem. I can't remember why 2006 Friday format was dropped? Did main drivers complain? I think that was ideal. Kubica and Vettel both flourished in that format.
