How can a cab appear just seconds after you tap? Think of searching for a nearby shop on your phone map: rather than scan the whole city, you focus on places near you. Now imagine the city divided into small areas, mostly hexagons. H3 is a system that places locations into these cells. Your pickup point lands in one cell, and the search can include its neighboring cells to look for possible drivers nearby. Like your shop map, that turns a citywide search into a nearby one. But hexagons don't book your ride. They make nearby locations easier to organize and search. Separate dispatch logic chooses which driver gets the request; a cell alone can't make that choice. So what makes the quick match possible? H3 can narrow locations to nearby cells, like finding nearby shops; dispatch chooses the driver.
