Indianapolis (AP)
The bewildered crowd at Indianapolis Motor Speedway was left pointing and gawking as they tried to figure out why the majority of the field was climbing out of their cars.
Fans were booing and some threw water bottles on the track in disgust. After just 10 laps, many spectators began heading for the exit gates. There were reports of thousands of fans showing up at the ticket office demanding refunds, and that police had been called to keep the peace.
Indianapolis Motor Speedway boss Tony George didn't immediately respond to an interview request by The Associated Press.
This event already draws just a fraction of what other races here do. Less than 100,000 come to this race, compared to a crowd in excess of 300,000 for the Indianapolis 500.
Sunday's debacle will do nothing to improve that.
"Quite frankly, the fans got cheated," Formula One boss Bernie Ecclestone said.
Scott Brombacher, a fan from California, said he was disgusted as he left the race.
"I love Formula One ... it just aggravates me," Brombacher said. "I spent a lot of money and took a week off from work to come out here. To have all this happen at the last minute is just disgusting."
