Did you watch the video? They were concerned because she was walking on the wrong side of the street facing away from oncoming traffic. That is what they said from the very beginning. They had come up behind her and she hadn’t noticed them, nor had she noticed a truck that had had to stop behind her to avoid hitting her as she veered out towards the center of the street. They were right to stop her and she was very defensive instead of responding to their courteous concern.
I have stopped to caution a neighbor on my street for the same thing. The sun blinded me momentarily and I had a scare when he came up suddenly on a dip in the road. Its not safe to walk on the side of the road in the same direction as the traffic and she should have already known that but when she needed to be reminded she should have thanked them.
we had a death in our townships a few years back where woman was hit from behind walking on the wrong side of the road.For a short time police were cautioning people that the law says to walk facing traffic. I don’t know if they do that any more but walking with your back to traffic with ear buds invites disaster.
