actually, there are several types of the film, using different technologies, one of them being opaque, and would not really work nice in the automotive application...
there is another one, PSLD (or something to that effect), that one actually darkens gradually, depending on the level of voltage applied, as opposed to instanteneously turning opaque, as in the SCD (or other 3-letter abbreviation, don't remember exact letters)
