My frustrations are mostly with people, frankly.

A huge problem is that people are not self-aware: they cause major problems just by being in the way (whether it’s car traffic on roads, or foot traffic on sidewalks, or traffic in shopping aisles, etc.). They desperately need a clue.

Maybe there is a technological solution: some sort of location-based system where you receive a message saying “MOVE; the people all around you have voted, and agree: you’re IN THE WAY”.
