Tragedy is always hard to talk about and unless you can learn from it and correct problems leading up to accidents it is pointless to talk about them. My wife and I were members of the International Council Of Motor Sport Sciences and had our own firm called Racing Safety Research and tried to investigate accidents and provide a clearing house for solutions and there are a number of firms that do that. Perhaps that what is needed is a national group similar to ICMS that could gather a route information to the affected mfg.
or track without bias and understanding that it is a dangerous sport but there are ways to reduce the hazards. I really wish there was a way to educate the bullet proof rookies.
