| Issue | Fix | |-------|-----| | Low FPS | Reduce zoom to 16, disable reflections | | Choppy loading | Preload tiles within 500m radius using TileLoadStrategy | | Mobile overheating | Cap FPS to 30 using setInterval instead of rAF | async function snapToRoad(lat

| Usage | Requests | Cost (approx) | |-------|----------|---------------| | 10 min driving | ~600 tile loads | $0.30 | | 1 hour daily | 10,800 loads | $5.40 | | Free tier credit | - | $200 (covers ~37 hours) | Limitations & Alternatives | Limitation | Workaround | |------------|-------------| | No dynamic objects (traffic, pedestrians) | Add custom Three.js animated models | | No off-road driving | Snap to roads or use Mapbox Terrain-RGB | | API key exposed in frontend | Use Firebase Functions proxy |
