Lotus, Really? Wow. Crying someone said a curse word. Hmm. Oh well.
Back to the discussion. I think all race organizations control their designs. Look at Nascar, IRL,F1. The first two all run the same chassis in their league. Motor size as well and in F1 they tell them which tires have to be ran like a spec tire or scrubs. So ROAR and IFMAR and any other sanctioning body tries to limit technology for cost and fun control.
It's harder to fix a problem after it happens than to head it off before it becomes a problem.
