The 15-minute city is a movement to get city councils to strive for cities where each neighborhood is walkable and most amenities are located within a 15-minute walk. However, a mass protest against this movement occurred in Oxford, England, primarily because protesters conflated it with another plan to restrict cars in the city center. The restriction plan was to be enforced with automated license-plate recorders (ALPRs). The swivel-eyed loons (as the protesters are called) believe that such a scheme constitutes pervasive location-tracking surveillance, which could be leveraged to attack disfavored minorities. They are not wrong.
