Bro I hardly see drivers look up from their phones while making turns these days, much less while stopping for pedestrians. It's way more common to see fellow drivers looking down instead of up, it seems like. Sometimes I like to honk to get their attention.
As a pedestrian, I often feel like I need a horn as well to get their attention, or at least cause them to start noticing that they ignored my right of way.
I think I remember reading some kind of study that showed if you make eye contact with a driver when crossing the road, you force the driver to recognize your humanity and realize you are a human being so they are less likely to dissociate and hit you
