The fact is, if you remove the overtaking oppertunity from the OP's situation, it probably eradicates all causes of the relevant 'failure mode', whether it be poor driving or just bad layout..
Yes, but following this argument, lets make everyone do 10 mph as it removes the possibility of a lot of accidents.
All I am arguing for is that instead of just looking at the outcome of accidents (Fatalities etc) and deciding something needs to be done, it should be down to what caused it. If that were the case, a lot of speed cameras wouldn't exist, and a lot more driver education would be taking place.
I'm sure someone got a Freedom of Information request through showing that a new speed camera, which need to have a certain amount of fatalities to occur before being placed, was due to a drunk man falling from an overhead walkway into the carriageway, yet a speed camera went up.
