Thats true, but to sell so many consumer range stuff they need the high ticket, high publicity top of the range pro stuff to be highly visibility. Why do you think Yamaha, Honda, Suzuki etc throw shed loads of money at racing? And pay the likes of Valentino Rossi the amounts they do? It sells the showroom stuff, thats why. Cameras are no different.
I agree with your example concerning racing, but I don't agree that the situation is the same with cameras. The average P&S-to-Rebel consumer wouldn't even have a clue what "full-frame" meant, let alone care if the 1Ds IV is a better camera than a Nikon D3x.
Infact, to be rigorous, the situation is more complicated than just that. The concept you're alluding to comes down to marketing; that is, big ticket items giving exposure. In that case, since the average consumer wouldn't have a clue what the 1Ds IV was (infact, I'd be willing to be most wouldn't even know what a 50D was), the fact that it exists would appease that logic enough. In the end, a sub-par 1Ds IV isn't going to deter a P&S owner buying a Rebel, provided the Rebel has a good price and a healthy list of features relative to similar models of competing brands.
