An Event Data Recorder is an electronic module or software function that captures critical vehicle data in the moments before, during, and after a collision. It logs parameters like vehicle speed, throttle position, brake application, and seatbelt status. Investigators and manufacturers extract this data to reconstruct accidents and analyze safety system performance.
I pulled the EDR report and it shows he was doing eighty with zero brake pressure before the airbag deployed.
