How to Secure Digital Evidence After a Smart Car System Failure

Modern vehicles record crash-related data that can explain incidents, and preserving it quickly matters because logs and footage are easily overwritten. This explainer details what digital evidence smart cars store, including EDR data, ADAS records, telematics, GPS, and software logs. It outlines how dashcam footage, dashboard alerts, and manufacturer app histories can support reconstruction when system failures are suspected. Recent Tesla and Waymo cases illustrate how software records documented crash circumstances. Guidance covers photographing warnings, saving timelines, requesting diagnostics, and asking all parties to retain data without updates or resets. It also flags risks from towing, repairs, reboots, and software updates that may erase critical material.
