(D) the information is retrieved for the purpose of determining the need for, or facilitating, emergency medical response in response to a motor vehicle crash.
As an EMT who has attended a number of MVAs I don't need no black box to help me determine whether there was a significant mechanism of injury. I'm certainly not going to be spending time fannying about trying to read out the black box when I have patients who need my help right now.
I'm sufficiently well trained to determine for myself whether someone requires treatment and I don't see how information from a black box is going to "facilitate" the limited treatments I am permitted to perform as an EMT-B.
That said, if law enforcement can retrieve info like speed, accelerations etc and transmit that to the receiving facility I can see the utility.
