Have you ever sat at a red light at 2 AM with no traffic in any direction and waited anyway? Have you ever rolled through that same red light 2 AM and felt vaguely guilty about it?
Of course you have. The traffic light is the most obeyed command in human history. Rarely enforced (unless you're in the UK like Marc). No officer in sight. Just a coloured light on a pole, and a near-universal agreement to stop when it's red and go when it's green.
This episode traces the humble traffic signal from the gas-lit lantern that exploded outside the Houses of Parliament in 1868 (yes, exploded, three weeks in) to the adaptive AI systems that watch real-time traffic and adjust timing in milliseconds. Along the way: railroad colour conventions, William Potts in Detroit and Garrett Morgan in Cleveland, the political question of whose green is longer, the inductive loop that can't see your bicycle, and the moment where you discover that the colour you grew up calling yellow is officially called amber once you cross an ocean.
Ride along with Marc and Renee through another look at a technology that became infrastructure as it spread beyond its humble beginnings.
