If Company A spends $50 million a year in racing who is to say that Company B spending $50 million in more direct consumer-oriented R&D isn't servicing their customers better or producing a better product?

I prefer more direct measures. I wouldn't buy a car because the manufacturer races. If that truly trickles down and makes a better car, than show me it is a better car. Don't point to racing as proof that the car is better.
