Exactly. The point is get the necessary equipment and personnel to the rider for stablization procedures. Hell fire they do in World Cup ski races on the side of snow covered mountain.
I have seen ski patrolers drop into double diamond extreme runs with sleds in driving snow storms and stablize neck and back injuries.
"open air, gravel traps....." jesus.
From the rules:
5.3.7.4 Track Ground Posts
These are placed at suitable locations and in sufficient numbers around the circuit
to provide rapid intervention and evacuation of the rider from danger with the
minimum of delay. The personnel must have sufficient training and experience to
take action autonomously and immediately in case of an accident.
Personnel:
• Doctor or paramedic (or equivalent) experienced in emergency care
• Sufficient number of stretcher bearers
Medical Equipment:
• Equipment for initiating resuscitation and emergency treatment
• Cervical collar
• Scoop stretcher
• Technical Equipment:
• Radio communication with race control and the CMO
Adequate shelter for staff and equipment should be available.
They have all they need to stabilize the rider at the ground post. They must be able to reach riders within 30 seconds (running across gravel traps, not as butch as skiiing, obviously).
The real problem is that in such cases, there is much more going on than just spinal injury. The official report on Simoncelli said he had neck and head trauma, as well as chest trauma. They had to drain blood from his lungs in the ambulance. Injuries in motorcycle racing are massively more complex than they are in football, because being hit by a 300lb motorcycle made of steel and traveling at 150 mph is a lot more forceful than being hit by a 300lb defensive end at 20 mph. The DE is wearing padding, too. Even in skiing, the energies are much lower, they may be reaching 70mph, but it's not often they slam into a tree at that speed. Injuries are therefore less complicated.
The problem with motorcycle racing injuries is that the first task of the medical personnel is triage, prioritizing the worst injuries, and often, all of the injuries are life-threatening.
