Well automated traffic lights didn't start being mass installed in cities until after 1910, and by that time high wheelers had largely been abandoned in favor of "safety bicycles" with both wheels roughly the same size as today. Most highwheeler riders in their day did not have to contend with red lights. Also roads and streets were still horse and cart populated, which was more bike friendly than with cars. There were far fewer vehicles per person of every sort than there are today, and they all moved slower.

After the total takeover of cars and traffic lights in the 1920's, the only people on high wheels bikes were historic bicycle buffs, who I imagine might avoid city streets with lights- I know I would if i were riding one.
