I am about to turn right on a green light. The walk signal is on. There is a pedestrian on the sidewalk slowly approaching the intersection to my right - but is a few feet away. I come to a complete stop to wait for them. As they get closer - still quite a few steps from the curb - they slow almost to a stop and it seems to me they are not going to cross but are going to follow the sidewalk and go right.
They are still away from the curb. I very slowly make my right turn. Looking in my rear view - I see that pedestrian cross and feel terrible. I do not honestly believe I endangered the pedestrian or cut them off and they did not appear distressed.
I'm just suddenly very confused. I'm a cautious driver and I'm wondering - where is the line between waiting for a pedestrian who is approaching the intersection and needlessly impeding traffic by waiting? How close do they need to be to be considered "approaching?"
In your particular situation, I wouldn't feel too bad. It sounds like the pedestrian knew exactly what they were doing and they wanted to cross behind you, rather than in front.
