   • Verify logging status through the driver dashboard or Telemetry GUI.

2. Driving Session

   • Begin driving session.
   • Access the Telemetry GUI through a web browser to view live vehicle data and monitor logging status.

3. Data Processing

   • End driving session.
   • Stop CAN bus logging through the Telemetry GUI.
   • Raspberry Pi backend processes recorded data and generates CSV and PDF reports.

4. Data Retrieval & Shutdown
