Indianapolis Motor Speedway officials were on Wednesday still mulling over their response to Sunday's US Grand Prix, which fell flat at the famed circuit amid Michelin's tyre troubles.

Seven teams supplied by Michelin failed to start the race, leaving just six cars competing before a first bemused and then angry crowd of more than 100,000, some of whom are demanding their money back.

"Nothing has changed at this time," speedway spokesman Ron Green said Wednesday. "We are not issuing any refunds.

Earlier on Wednesday, International Automobile Federation (FIA) president Max Mosley suggested that Michelin should offer to compensate fans, and let the speedway co-ordinate it, while also allowing those spectators to return next year free of charge - if the race takes place at Indi.

For the time being, Green said, officials at the circuit were encouraging fans who attended the race and "had concerns" to write to the IMS and include their ticket stubs and addresses in case further action is taken.

While it has been widely speculated that the fracas will spell the end of Formula One at Indianapolis - where the US Grand Prix has been held for the past six years - Green said that, too, is still unknown.

In the immediate aftermath on Sunday, IMS president Joie Chitwood said speedway officials would be considering whether to ask for a refund of the sanctioning fee they paid to Formula One, as well as whether to pursue future F-1 races at the home of the Indianapolis 500.

"We will be seriously looking at our position on the response we give in the next couple of days as to the event and whats appropriate for us to do," Chitwood said Sunday.

"That position hasn't changed," Green said on Wednesday, adding that no decisions would be taken in haste.

"Certainly we have a commitment to make the best choice possible, not only for the speedway but for its fans and for central Indiana," he said. "The Formula One Grand Prix is a major event, and we have a level of responsibility to the community."

And, Green said, track officials had reason to think Sunday's sorry spectacle might not have completely turned off local Formula One fans.

"I will say that Monday brought a new day," Green said. "It was the first day for fans to renew their tickets for next year's event, and we were surprised by the number of people who stood in line to renew."
