The '15-Minute City' meme centers on the urban planning concept where all essential services are reachable within a fifteen-minute walk or bike ride. While initially a serious proposal for sustainable urbanism, it became a viral sensation in early 2023 when online discourse shifted toward conspiracy theories regarding government surveillance and restricted movement. The meme now serves two primary purposes: urbanist enthusiasts use it to highlight the joys of walkability and public transit, while critics and trolls use it to satirize the perceived dystopian future of 'climate lockdowns.' It often features maps of modern European cities contrasted with sprawling suburban parking lots.
