So if it is not in the thermal IR range, I suppose it is not particularly useful in seeing humans and other warm-blooded animals in the dark? As far as I know, there is not much ambient IR at night time. What I would find most useful when driving at night is glasses that attenuate intense light rays, so that the increasingly-powerful oncoming headlights will not be blinding. I have a vague impression that channel-plate image intensifiers have this property, on account of individual channels saturating in their ability to release electrons.
