How the work runs

The pressure that made this worth automating, the steps the system runs, and what came out the other side.

Pressure & Trigger Points

Unplanned roadside vehicle breakdowns cost over $2,500 per incident in towing, cargo transfer, and missed SLA delivery penalties.
Standard periodic servicing (every 15,000 miles) failed to catch sudden turbocharger seal failures, transmission overheating, or brake pad degradation on severe routes.
Telematics data from CAN bus systems was overwhelming, producing millions of raw fault codes daily without actionable priority.
