Did you know jaywalking became illegal progressively across the United States between 1911 and the late 1920s with Kansas City passing the first anti-jaywalking ordinance in 1911 ? (The concept was cemented into law after the auto industry and safety organizations championed the rules, culminating in a nationwide Model Municipal Traffic Ordinance in 1928 after automobiles became more common and pedestrian fatalities spiked. They invented and popularized the term "jaywalker"—using "jay" as derogatory slang for a naive rural rube—to shift the blame for accidents from reckless drivers to people walking in the streets.)
