What it shows

Spatial indexing (H3/S2) prunes candidate drivers within a 3km radius.
Scoring engines balance ETA, driver rating, and acceptance probability.
Distributed locking on offers prevents race conditions between drivers.

The takeaway

Efficient dispatch relies on geospatial indexing and fast pessimistic state locks.
