What it shows

Geohashing converts 2D coordinates into 1D alphanumeric bucket strings.
Matching algorithms query the rider's cell plus 8 adjacent neighbor boxes.
In-memory spatial indexes keep location updates under 10 milliseconds.

The takeaway

Spatial indexing converts quadratic distance scans into constant-time key lookups.
