A few simple rules could be 24L-1000cc-15,000rpm. The racing would be closer than it is now. The costs would also tumble, and the sport would be teeming with new manufacturers. Would it still be MotoGP?
Few people care about the spirit of GP anymore b/c the MSMA have taken the sport to a new low.
The argument about the future of GP reminds of politics--never-ending false dichotomy. Fans are led to believe that liberal formulas and close racing are mutually exclusive. They either support bad prototype formulas, which produce awful racing, or they push for close racing in the form of spec equipment. Two different kinds of suicide. Racing with traditional, open rules is mercantilism. Spec racing is technological communism. Neither work. Has anyone realized that the production market is passing by racing competition? MARKET
The market, a discovery about the tendencies of human kind, demands that open rules and competition occupy the same space. If they do not, legal/economic systems will be created to make sure both are present at the same time. Compared to mercantilism, communism is vastly superior. NASCAR rules the world, but NASCAR is merely a spec of dust in the eyes of the production market.
Open rules and close racing or board the place up until the GPC has an epiphany.
