Proposal to increase yaw rate recording frequency to 10 Hz. Yaw-rate data recorded at 2 Hz corresponds to one measurement every 500 ms; increasing to 10 Hz provides a measurement every 100 ms, resulting in a fivefold improvement in temporal resolution. This enhancement significantly improves ability to reconstruct pre-crash vehicle dynamics, identify vehicle instability onset and progression, and evaluate Electronic Stability Control functionality. A yaw-rate recording frequency of at least 10 Hz reduces temporal uncertainty from 500 ms to 100 ms and enables more accurate reconstruction of loss-of-control events, vehicle rotation, ESC interventions, and driving dynamical issues.
