I, for one, think that these appendages are the physical manifestations of human brilliance. Every time someone introduces a new bit, I immediately think to myself "I would like to meet the person that thought of that!" Discussions with those type of people would be a huge interest to me. All of that wisdom to learn... Very impressive.
I agree with the oxy moron of restricted racing, but as has been posted numerous times, there are reasons, and we as the fans on the outside are not in an informed enough position to even comprehend the reasons why. Regardless of the millions of different views on what F1 should be, there is a common belief amongst all fans, and that is the potential of F1.
Winglets, KERS, Aero, motive power and logistics. All areas of potential that F1 pushes to the bleeding edge.
I, for one, am constantly and utterly amazed at the evolutions that the cars undergo, whatever route the designers take. If all of those winglets disappear, the brilliance will fade, as will the performance that the fans currently enjoy.
Be very careful what you wish for, because it was someone elses wish for it to be in its current configuration, and look how well that is working...
