I don't dispute this at all. I'm just putting forth CNG, especially bi-fuel vehicles, as an alternative for the form factors for which EVs aren't practical, aren't offered, or simply don't make sense.
On the other hand, the marginal improvement of only "an 18%-19% reduction in the overall life cycle environmental impact" is somewhat disappointing, as it is well within the variation that one would expect in driving habits (miles driven), particular choice of vehicle, etc.
