A disastrous outcome was avoided by Bill D doing as a do, and dropping back a bit. However, if Bill D hadn't of provided that space, how were the on-coming drivers expected to ensure their own safety? I have been an oncoming driver in a similar situation driving south of Kings Lynn as I originally mentioned in this thread - not so much a case of barreling down a line of slower moving traffic, but an idiot trying to overtaking another idiot, and both refusing to drop back. And instead of barrelling the other idiot Bill D refers to should only overtake when there is a sufficient space in front of the vehicle being overtaken and there is sufficient road visibly free of oncoming vehicles to complete the maneuver.
