They are not in the business of promoting anything beyond NASCAR. They do not see it as their obligation. They are track owners and promoters of NASCAR. The payment of a sanctioning fee by ISC for an IndyCar event is an investment in benign neglect: they don't promote it so they can say the product is weaker than our main product for promotion.
Before ISC and corporate track ownership, a track would clear out any semblance of the series not running there that weekend and dedicate themselves to bringing in people to see the featured series. For example, Phoenix. Before ISC, I would go there and the city would be engaged in an IndyCar event and the track owners would make a promotional week of it on local TV and radio. You knew IndyCar was in town and you might be lucky to get a mountainside seat at the last minute.
Then ISC. Then the yearly excuse why they didn't promote IndyCar. We conveniently gave them an open wheel schism...no doubt in that. However, it doesn't absolve you from the promotional aspect of the event in which they signed on to promote.
I read the ISC financials for 2011. They took advantage of major one-time loopholes to give the appearance of profitability in 2011. They still have construction notes with Charlotte-based banks that the banks refuse to refinance at a lower rate and longer term. Translation: their cash flow and credit-worthiness are at question.
They need events at their facilities to increase cash flow. They are going to dab their toe in the IndyCar pool and try to get them back at a few ISC tracks. I'd double the sanctioning fee and demand the promotional direction be handled by someone else and use their promotional staff for intern-like duties. They've proven they don't want to promote anything beyond NASCAR. Relieve them of that worry and take it over for them. They won't sign on the dotted line because benign neglect is what they provide non-NASCAR customers and that is what they want: to be the tallest midget in the room.
