Each offline drive records its quarterly cache generation, Overture release and actual OSM acquisition dates. OSM footprints take precedence over overlapping enrichment. Names and measured heights are only used when present; other heights remain stylizations.
The shared helper redistributes the attributed geographic database alongside its source references under the applicable open-data licences. This does not change the game code's licensing.

The bundled Fort Kochi extract is real OSM data retrieved on 2026-09-06 from api.openstreetmap.org. The source JSON is included in sample/fort_kochi.json under ODbL. Building heights, colors, and vegetation infill are stylizations, not surveyed facts.

Engine audio: original synthesized sounds created for Cab Hero.
Car: naturally aspirated even-fire V6 inspired by the Challenger SXT 3.6 L Pentastar,
three firing pulses per crank revolution, separate exhaust-bank resonances and intake noise.
Idle at 900 RPM; loaded and coasting pairs at 1,800, 3,300 and 5,400 RPM.
Tuk-tuk: four-stroke single-cylinder combustion cadence (one pulse per two crank
revolutions), with a stylized two-knocks-per-second idle over a quiet 1,200 RPM bed;
loaded loops at 2,400/4,800 RPM, overrun at 2,400 RPM.
32 kHz mono PCM. These are designed sounds, not recordings of a particular vehicle.
