IndyCar officials don't believe the construction of the fence at Las Vegas Motor Speedway played a role in the death of two-time Indianapolis 500 winner Dan Wheldon.
Instead, the larger factor was the wide grooves at the speedway that gave drivers a "limitless racing surface."
The investigation into Wheldon's fatal accident determined his head hit a post in the fencing, creating a "non-survivable" injury. Las Vegas is owned by Speedway Motor Sports Inc., and the organization constructs its fences with the posts inside the wiring.
IndyCar president Brian Barnhart says there is no indication Wheldon would have survived had the post been on the outside of the mesh wiring.

The report finds several factors contributed to what became a "perfect storm," and no one reason could be singled out as the sole cause of the accident. IndyCar found it is "impossible to determine with certainty that the result would have been any different if one or more of the factors did not exist."
The race had a season-high 34 cars and was held on a high-banked oval, and IndyCar CEO Randy Bernard says the size of the field and the banking itself were not solely responsible for the accident.
