Schrodinger's Intersection

Two delivery guys on electric bikes arrive at the four-way stop at the same time, one going east, the other going south. They neither of them stop, instead edging out into the intersection on a collision course in a game of Delivery-Guy-Chicken until they are forced to stop or hit one another.

Which they do, i.e., stop, leaving them both out in the middle of the road, and posed with a dilemma. They must go; they cannot go; politeness would dictate that one of them let the other go first, but neither will give way to the other and show weakness, leaving them there, eyeing each other with a mix of exasperation and menace, and I zip past them on my scooter before the question is resolved, so for all I know they may there still, until their bikes' batteries run out of juice.
