As tributes to Dan Wheldon flow in from all over, the motorsport fraternity, who were left stunned by the Brit driver's death in the circuit after a 15-car crash, are already looking at measures to improve driver safety.
The IndyCar officials have announced they would review the incident to absorb whatever lessons can be learned while the Formula One authorities are already considering going back to closed cockpits.
Although the exact cause of Wheldon's death is yet to be examined, it is understood that the primary cause was his car entering the catch-fencing around the track headed by the open cock-pit, leaving him with only his helmet for protection.
Flying particles have caused quite a few close-calls in motor sport. A stray spring from a Brawn GP car injuring Felipe Massa comes to mind, while the death of Henry Surtees, son of world champion John Surtees, who was struck by a wheel that had dislodged from a car ahead in a Formula Two race is another incident.
According to the Guardian, the FIA - Fédération Internationale de l'Automobile - had already looked into adopting closed cockpits earlier this year, although it is likely to be unpopular with fans who like to be as close to the action as possible.
Paul Tracy, one of the 15 drivers involved in the crash at the Las Vegas Motor Speedway on Sunday, wants to see something done about the catch-fencing which he claimed was the most obvious failing to safety in IndyCar racing.
I think there can be improvement made in the catch fencing, he said. There has been so much improvement done with the SAFER (Steel and Foam Energy Reduction), walls, and heads and neck restraint systems, and the seats and the cars have got safer and safer.
But what has really stayed the same is the catch fencing along the walls. Once the cars get in there it just starts ripping the cars apart. So maybe that is the next thing that needs to happen in terms of safety for race events.
