The EDR event was real — but it was the wrong collision

Case question
How can a technically valid stored event be excluded from the collision under investigation?

What the evidence showed
A Ford Escape matter included independent video and damage photographs. The recorded pre-crash speed did not fit the collision shown by that independent evidence, so the central task became event authentication — not simply reading the newest stored record.

Practical takeaway
A valid EDR record is not automatically the loss event. Match chronology, pre-crash behavior and physical evidence before attribution.

Reading the exhibit
Deceleration and distance-to-impact columns are derived from sampled speed, not independent EDR measurements. Distance is approximate displacement before the final pre-crash sample; sampling gaps, wheel slip, sensor latency and incomplete data can affect it. Read the calculated values with scene evidence and the source report’s limits.
The source evidence exhibit is provided below.

Evidence exhibit
Complete stored-event pre-crash table from the Ford Escape report. Source pages 3 and 4 are shown in order, separated by a blank gap. The table must be interpreted with the independent video and prior-collision photographs described in the case narrative.
