Idk about you, but if I see a human start to step into the road I slow down/stop depending on how close they are. Someone stopped and facing the road looking both ways obviously may be attempting to cross, even if "illegally"

I'm enough of a jerk that sometimes, if they are at the edge of the road, I will stop and honk. Even if they are engrossed in their phone. Because, in my jurisdiction, it is illegal to not give the pedestrian the right of way at a crosswalk. Pedestrians who aren't planning on entering the roadway shouldn't stand at a crosswalk and not enter.
