Telemetry is the real-time data stream sent from the car to the engineers in the garage. It includes everything from throttle position and brake pressure to tyre temperatures and gear changes. If a driver sneezes mid-corner, someone in the data center probably knows about it. It helps teams fine-tune performance, catch early signs of failure, and occasionally proves that, no, the car wasn’t “undriveable” — you just braked too late, champ.
