To me the difficult bit is where do you draw the line (this explanation might be tricky due to text form). I get you have to give way if you've turned into a junction, but if the pedestrian is say 1 metre away do you still stop, what about 2 or 3? To me common sense would be when you've finished you're turn you no longer have to give way I.e. wheels all straight, but still seems a bit ambiguous.
For me as a pedestrian and Im sure most would be the same, is that Im waiting at a junction to cross but will only walk when it is clear or when the driver acknowledges its ok for me to cross, otherwise I wont bother. As a driver or cyclist, I will acknowledge Ive seen them and indicate its ok for them to cross. If they arent waiting to cross then I will turn as normal
