Auto racing is not one thing — it is a whole field of distinct, separately run categories, each with its own championships, audiences, and calendars. Every one of them promotes itself. None can sit above the sport, because each is a competitor within it. AutoRacing.com is the exception: the exact-match name of the entire sport, held continuously since 1996, belonging to no series precisely because it names them all.
A position like this cannot be manufactured. A series can buy reach, technology, and audience; it cannot buy the one name every category already resolves onto. What a partner builds on it is the business; what the name provides is the ground nothing else can — the nucleus the sport has never had.
