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.
