Seems that even with all the crash protection of a modern GP curcuit, if your luck runs out there is little to be done.
I have to concur with this view. No amount of safety features can prevent the worst if your luck has run out. There are just too many variables.
I was with Wishywashyman at Gurston yesterday and it struck me that maybe particular conditions on the day may have contributed to the problem. All of the offs occurred on the same section of track, perhaps grip was diminishing as dust was being blown around, just speculation but who knows..... I'm sure there will be some kind of investigation by the race officials and BRSCC representatives.
Regarding safety precautions - in general I think the organisers do a reasonable job at these events, after all if you ripped out all the trees, widened the track, put in gravel traps everywhere etc. etc. it would no longer be the type of event that it is. And so long as the competitors vehicles are equipped with the necessary safety equipment long may these events continue.
Having said that I thought I saw some road cars competing without rollcages, didn't think about it much until afterwards. Maybe I was mistaken but these should definitely be required. Perhaps someone could correct me on this?
