As a regular pedestrian and cyclist I regularly come across situation where I have priority over a car, but given the "underlying" position that you are in you like to make sure that the driver of the car will yield. You need eye-contact for that or at least you would like to see any gestures. Unfortunately rather often these days that is not possible because of darkened door windows or sometimes even windshields. If you need to protect your eyes use sunglasses and don't pretend that you are a member of the mob.
