Despite the trauma for fans in that area, Larson was not injured. NASCAR has made driver safety a focal point since the death of Dale Earnhardt on the last lap of the Daytona 500 in 2001.
"Most of the safety elements in that car did their job," O'Donnell said. "The driver, as you saw, walked away. The car, however, got up into the fence. Our focus is going to be: If the elements in the car did their job, what do we need to do to the impact to the fence, and what happened once that car impacted the fence?"
O'Donnell also said that NASCAR is going to bring in outside experts., including Dr. Dean Sickling, who helped develop safety barriers at Indianapolis Motor Speedway.
"We have a partnership with the Indianapolis Motor Speedway where the SAFER barriers came together," O'Donnell said. "We'll enlist both of those parties as part of this process."
Sorenson gets ride
Annett recently underwent surgery for a fractured and dislocated sternum and is expected to be out six to eight weeks.
"It's an unfortunate situation for the team and Michael," Sorenson said in a prepared statement. "I have been to the hospital to see him, and he will be fine, but it's going to take some time to heal. As a friend for a long time, my initial reaction was concern. I'm glad that he's recovering now."'
Annett was involved in an 11-car accident prior to the more spectacular wreck at the race's conclusion that injured spectators. Annett was taken to Halifax Health in Daytona Beach.
