"Jaywalking" was propaganda created by big auto, resulting in one of the fastest shifts in public opinion ever recorded.
In 1905, if you stood on a busy American city block, the street was a commons. Vendors worked the middle of the road. Kids chased each other between horse carts. Nobody owned it.
Then came the car, along with lawyers, the lobbyists, and the propaganda.
In 1923, newspapers blamed drivers for pedestrian deaths. By 1924, they were blaming jaywalkers.
The secret weapon was a slur. Calling someone a "jay" in the 1920s meant calling them a hick. Too dumb for city life. Stick it in front of "walker" and you didn't have a victim anymore. You had an idiot who deserved what he got, a Jaywalker.
Historians call it one of the most dramatic shifts in public opinion ever recorded.
