Until the early 1900s, people traveled by real horsepower – the kind fueled by hay. Then the automobile began changing American life. In those early days, driving was something of a free-for-all. There were no stop signs, traffic lights, proper lanes, brake lights, crosswalks, or speed limits. No driver’s license was necessary. Pedestrians crossing the street had to dodge any passing cars. One account stated: “Screaming pedestrians were scattered like ninepins. Some were bowled over or tossed against store fronts.”
