on the reconfigured LVMS track in the Craftsman Truck Series for Morgan-Dollar Motorsports in 2008 and for Team Red Bull in the NASCAR Sprint Cup Series in 2009 and 2010. Speed, in an interview he gave to Inside Edition on October 18, 2011, said that he declined to take the offer saying that the track conditions were too dangerous for Indy-type cars. Likewise, A. J. Allmendinger, who also had previous open-wheel experience, had expressed early interest, though he later declined, recalling, "[When] we raced CART at Vegas...it scared the living hell out of me."

The report also revealed that the right front pull rod of the suspension assembly penetrated Wheldon's survival cell, though it did not cause him any injury. The report recommended further investigation of this phenomenon, as it was the first
