Why Every Car Has a Third Brake Light

Why does every modern car have a third brake light when two already seem enough? The answer involves human attention, real-world crash experiments, and a surprisingly clever safety idea. Discover why engineers placed the third brake light high in the centre — and how one small red light helped change car safety. In this Doodle Reason episode, we explore the history, psychology and engineering behind the centre high-mounted brake light.
