What the evidence showed
In a GMC Sierra matter, the pre-crash record showed vehicle speeds around 30–33 mph in the seconds before impact. That objective time series provided a direct comparison point for a much lower reported speed.

Practical takeaway
When speed is disputed, use the actual time-series table and preserve its sample timing, units and OEM limitations rather than relying on a single summary number.

Reading the exhibit
The excerpt contains five samples from -5 to -1 seconds. It does not provide a time-zero speed. Its derived columns are report calculations and should not be treated as independent recorded EDR parameters.
The source evidence exhibit is provided below.
