A method for vehicle data management according to embodiments of the present invention includes receiving an accelerometer signal from an accelerometer mounted in a vehicle, determining an accelerometer specific force based on the accelerometer signal, receiving a speed signal from a speed sensor or GPS or other source on the vehicle, wherein the speed signal indicates a speed of the vehicle, determining an instantaneous acceleration of the vehicle by calculating a rate of change of the speed based on the speed signal, selecting a current observed acceleration as a lower value of the accelerometer specific force and the instantaneous acceleration, capturing video footage with a camera mounted on the vehicle, and flagging the video footage corresponding to a time when the current observed acceleration exceeds a preset safe force value.
