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.
