Thanks! That answers a couple of questions. It gets us back to the question: is it reasonable to assume the NiD-52 had one of these systems since the NiD-62 did?
Dramatically, this system is a mess -- by the time Our Heroine has the system pumped up, she'd be arrested or strung up from a lamppost.
I'm reminded of a Top Gear episode in which Clarkson et. al. got to direct a car chase scene in a movie. They insisted on making it entirely accurate, which included a 12-second close-up of someone activating a particular control in one of the cars. Needless to say, it was a really dull chase scene...
