So I'm watching TV, and this commercial for some GMC sport-utility vehicle comes on. It's all shades of metallic gray and factories and tough-looking blue-collar workers and big machines and sparks flying through the air and such. Then the voiceover starts: "This is unfamiliar territory for most luxury SUVs." ... Think about the implications of that for a moment. Not only are there so many SUVs that the really expensive ones created a subcategory of "luxury sport-utility vehicles", but now there are so many luxury SUVs that they need to compete against each other on the basis of how tough and macho they are. ... What the hell is wrong with this culture?
