A smartphone app plus a windshield IoT tag (3‑axis accelerometer and gyroscope) detects crashes and calls an emergency centre within two minutes by sending 100 Hz crash data to servers that validate the event. Ingestion uses files to S3 then Kafka running in Docker/Kubernetes, Java processors with GeoTools, storage in Postgres and reporting via Kafka → Postgres → Metabase, with TensorFlow experiments. Trial logs 330k km, ~30k trips over five months; planned rollout of 50,000 tags; challenges include many false positives from low 2g thresholds, insects, scooters and tag placement.
