I was riding into work in casual carpool this morning when I noticed a sticker in the rear passenger window: “PZEV”. This stands for “Partial Zero Emission Vehicle”. What!? Isn’t every vehicle a partial zero emissions vehicle? That’s just silly to document something as such. It reminds me of Simpons episode where the newspaper lady says “And to protect Mother Earth, each copy contains a certain percentage of recycled paper.” Lisa asks what percent and she replies “Zero percent…what, zero is a percent!” Which then reminded me of a recent XKCD citing more or less the same issue about asbestos in cereal.
Every vehicle is a Prius!
