Problem

We collect telemetry from millions of connected vehicles, including speed, braking events, OBD sensor readings, and ADAS alerts, and have to serve two teams from the same feed: safety analytics must react to an event the moment it happens, while predictive maintenance can wait minutes for aggregated trends. Vehicle location counts as personal data under European law, so raw coordinates can be retained only for the regulatory window while analytics reads a coarsened location. Design the pipeline that feeds both teams and keeps the location data compliant.

Summary

Every vehicle is a sensor. Deploy the pipeline to catch it all.
