Firstly, I don't admit to knowing much about the US EMS industry but I would have thought that the insurance companies (of the aircraft) would be a driver to safety. I would have thought simply showing them footage of NVG and unaided flight would convince them to quadruple an operators insurance bill if they deemed to operate unaided flights.
Other than that, the FAA should legislate NVG for EMS operators (and for Father Christmas).
