On positioning for vision (after safety, but before stability) the general guidance would be not to put yourself somewhere where you might give someone else an unwelcome surprise, or find yourself short of time to move out of their way. That probably means that to consider crossing the centre line you already have a fairly long view and are travelling fairly quickly.

To me that is tantamount to going looking for an additional view, i.e. a view we do not already have. Now, if it is to be done cautiously and safely by, if necessary, backtracking promptly from this bold positioining, and there is benefit to be had, I welcome this relaxation and added freedom in positioining, but what do you think? Am I misunderstanding what you're saying here?
Best wishes all,

Firstly, I'm not sure that I warrant the accolade of the collective "we", as in... "We now appear to be implying". These were my words and mine alone.
However, I understand the point that you are making which deserves an explanation from myself. The words that I posted should be expanded to read... [in my opinion] It's OK to position off-side in order to maintain and/or seek to extend the view that we already have. We must never move off-side to look for vision from a position where we do not already have an extended view.
In other words the the vision, and safety margin in terms of distance to the limit point, must be there in the first place before any decision is made to off-side, or continue to stay off-side, in order maintain and/or extend that vision. If the vision that we already have closes down and doesn't extend then yes, of course, we must return to our own side.
That's just my interpretation of how this is applied in practice.

Moving out early enough gives time to move back with no conflict, and as traffic speeds are probably below 20, IMHO quite safe. It avoids moving out blind in the final few yards of approach, which is then blind.
