Earlier quoted context omitted.
Jaywalking as a negative concept was pushed in newspapers by the auto industry and it worked.
I don’t think it was universally successful on the cultural front (in the US). There are many places where no one will give a shit if you jaywalk or think any less of you, though maybe the effect has waned over the years. Legislatively, yes it was pretty universally successful.
A more worthwhile thing to discuss is the prevalence of people ducking their heads or rushing across streets when cars approach, with a level of embarrassment that would better accompany being caught defecating in the street (well, maybe not in SF.) Our culture has so utterly failed around mobility that people are ashamed to be caught walking.
