You know that moment when traffic just... stops? No crash or orange cones. No rogue shopping cart rolling across three lanes, only a wall of brake lights stretching to the horizon like some kind of automotive punishment for sins you cannot remember committing.
Scientists call it a "phantom traffic jam." Sounds made up, right? Like something a traffic engineer invented to avoid blame. But the research is actually fascinating. It only takes one driver reacting a half-second too slow to create a ripple effect that backs up traffic for miles behind them. One tiny delay. One small lapse in attention. And suddenly three hundred people are late for work, cold sandwiches, and questionable life decisions.
