In the 1920s, auto groups redefined who owned the city streets. --- The idea that pedestrians shouldn't be permitted to walk wherever they liked had been present as far back as 1912, when Kansas City passed the first ordinance requiring them to cross streets at crosswalks. But in the mid-20s, auto groups took up the campaign with vigor, passing laws all over the country. Most notably, auto industry groups took control of a series of meetings convened by Herbert Hoover (then secretary of commerce) to create a model traffic law that could be used by cities across the country. Due to their influence, the product of those meetings — the 1928 Model Municipal Traffic Ordinance — was largely based off traffic law in Los Angeles, which had enacted strict pedestrian controls in 1925. "The crucial thing it said was that pedestrians would cross only at crosswalks, and only at right angles," Norton says. "Essentially, this is the traffic law that we're still living with today." […] Auto campaigners lobbied police to publicly shame transgressors by whistling or shouting at them — and even carrying women back to the sidewalk — instead of quietly reprimanding or fining them. They staged safety campaigns in which actors dressed in 19th-century garb, or as clowns, were hired to cross the street illegally, signifying that the practice was outdated and foolish. In a 1924 New York safety campaign, a clown was marched in front of a slow-moving Model T and rammed repeatedly.
