Phil, very sorry to hear of your accident and hope you & your wife make a full recovery
The locals know how dangerous this road is, I think it's still in the top 10 most dangerous UK roads for accident stats
The Police used to (may still) monitor it at weekends by Helicopter due to it's biker reputation, personally I avoid if I can - too busy in good weather and full of weekend hero's in pimped up VW's, sprinkle in some rain & winter fog and it's lethal
