> A situation cannot be simultaneously dangerous and not dangerous.
I didn't say that. I said her actions were dangerous.
It was in response to your comment:
> If I felt it was so dangerous that I needed to stop and offer unsolicited advice to someone I didn't know, I would feel responsible for their safety if I didn't offer them a lift.
If there is a sidewalk she can safely walk on, that is a not-dangerous situation, and and there is no need to offer her a lift. If she chooses to instead walk in the middle of the road, that changes the situation.
> the driver of a vehicle is the one in charge of a potentially lethal machine
Agreed. Again, there is nothing in this thread stating otherwise.
My point is that pedestrians need to walk responsibly as well.
> the chances of having to swearve to avoid people walking in the lane or having to think about the consequence of killing a mother and child are practically nil.
I think you are being too optimistic here.
