Despite Biffle's claim that the emergency responders at the speedway were "slow and unprepared," he had multiple sources to help him quickly. Kyle Busch, who was also involved in the test, was able to get to Biffle and help him out of the car.
Biffle also claimed that he wasn't offered any advice, including going to the hospital. LVMS general manager Chris Powell issued a statement saying that "Mr. Biffle signed a form saying he refused being transported and he himself wrote 'I feel fine' on a release document.
Powell went on to say: "Mr. Biffle's statement was written as a response to a demand on the document that requested a reason for his refusing to be transported."
It may be hard to believe, but the speedway officials can't force anyone to go where they don't want to go.
On that Friday five weeks ago, Biffle flew home to North Carolina and was diagnosed with a dislocated shoulder.
Seems that now there's a dislocation somewhere in Biffle's brain cells.
To read the statement from Powell and the AP article written by motorsports writer Jenna Fryer on Biffle's return to the track since the Vegas wreck, here's a link:

Unfortunately, I wasn't there when the wreck went down, but I do know, based on being there at various events over the last two years, that the LVMS safety crews do an outstanding job.
Mistakes and poor decisions happen, but the LVMS safety crews did all that was necessary with Greg Biffle to make sure he came out of the wreck in tact, even if his favorite car was ruined.
