Given the way my woman purred this morning, must be a third category. Those who reject the leftist Malthusian environmental orthodoxy and seek to live the best life possible through technology and, yes, high energy consumption. If I need to haul rocks, I can do it. If I need to give 5 people a ride, and all their gear, that too. Try that with your Smart car!. Heck, I could put one of those in my truck's bed.
