Roger Penske is another successful businessmen outside racing who, like Shoe, could almost certainly fund his racing through the marketing budgets of his other companies but for the most part has refused to. Though also like Shoe, he has made occasional exceptions to that rule over the years. It's true that these guys do sell other companies on the value of sponsorship, and one might say if it's so great, why aren't they jumping all over the chance to take advantage of it themselves? But I think both of them are smart enough businessmen to realize that there is a moral hazard to sponsoring yourself. An outside business is (or should be) keeping a clear, objective head and making sponsorship decisions based on a sound business case. It's difficult to count on being able to do that yourself when you are funding your own dream and passion.
