Ciro was talking about "what it should be" and that perfectly answers the question title of this topic.
What Jersey Tom states is "what it is" according to his opinion.
Let me get philosophical when I think that our laws and rules are perfect in intention and spirit but our society is not. Thus, F1 should be relevant to modern transport, but nowadays it is not.
It has been said many times that any luxury car has more sophisticated suspension than any 2008 F1 car and it is true, but lets also admit that that technology came from early 90´s F1 cars.
So, my conclusion is: F1 has been relevant once but now the senile and rancid lidership have turned it othrwise.
