For years, I thought that narrow slot between my car’s cup holders was just a quirk of the plastic molding—a design afterthought with no real purpose. You know the one: that slim, slightly awkward divider sitting between two drink wells, too small for a phone, too odd for coins, and seemingly useless for anything at all.
I ignored it. Sometimes I’d wedge a pack of gum in there. Occasionally, my phone. Once, I even tried balancing my keys in it—a decision that ended exactly as you’d expect during a sharp turn.
