Chrome = cool. Giant spoiler and undercarriage lights = not cool.
Every car buff knows chrome is cool. That might be why they used the word "chrome" for these Chromebooks. It might also be why they didn't use words like "fuzzy dice" or "ironic political bumper sticker" or "airbrushed naked woman holding a sword" for these Chromebooks. Those things just aren't as cool, you see. Sorry if nobody made that clear before you decorate your car.
