If you could replace all traffic lights with something else, what would it be?

This prompt invites playful problem-solving and a bit of social imagination. Traffic lights are a shared frustration and a shared agreement — everyone understands them, even if no one loves them. Replacing them opens the door to humor, creativity, and commentary on how people behave when rules, patience, and cooperation are involved.

As you imagine an alternative, think about what you’d want to change about how movement and waiting feel. Would your replacement make things more efficient, more entertaining, more human, or more absurd? The “why” behind your idea can reveal how you think about order, chaos, fairness, and how much fun (or friction) you think daily systems should have.
