There are lots of those idiots everywhere. I know one who I had a few arguments with while used to brag about the supposed lower environmental impact of hybrids, but recently bought a Renault Clio II Campus (still available brand-new in Brazil). At least it can run on ethanol, while the currently-available hybrids usually can't
Anyway, we can't really neglect the effect of some tailpipe emissions, but there is also some huge energy expenses that come from industrial processes to refine petroleum, or to make chemicals like DEF, and also the logistics involved to make it available to the final customer.
