Thank you for this, Tab! You’ve excavated the true purpose of #WeekWithoutDriving: instead of a campaign meant to exhort work-a-day ppl with families to avoid driving, it’s designed to invite electeds to see for themselves how abysmal not driving is, and based upon this seeing, effect change

How much of children’s mental health struggles are attributable to their auto-dominated environments keeping them from easily exploring their environments and chance encountering friends and acquaintances?

U.S. traffic deaths fell for a fourth straight year. However, pedestrian and bicyclist deaths rose 8% since 2020. When a total improves, for whom has the system become safer? transportationtodaynews.com/news/38851-t...

2. Exploit a common “threat narrative”—e.g, "the government wants to take away your car." Don’t deny this narrative; offer a competing threat narrative: "People you love are falling ill because of others' driving choices." Health threats are harder to dismiss than convenience threats.

Upshot: it’s not worth trying to persuade "drivers" to change beliefs about driving. Instead, split the driving coalition: 1. Identify different interest groups within "drivers." Suburban commuters, freight drivers, ride-share drivers, and elderly drivers, as they don’t share identical interests.

In the spirit of #weekwithoutdriving, a few tips on inviting others to see what you see: But first, political support for driving is driven by coalition goals, not ignorance. Even the beliefs people hold depend on which beliefs help strengthen their coalition and weaken opposing ones.

Fayetteville had 30 approved traffic-calming projects sitting unbuilt. A neighborhood group grabbed paint and finished a project in a weekend, earning more trust on a Saturday than months of speaking to council. What counts as political: the speech, or the paint? www.strongtowns.org/journal/2026...

I often wonder whether people, many generations from now, will learn about our organizing society around the needs of machines which kill and maim so many humans and non, hasten natural disasters, bankrupt people, rendering them ill and think “was it at least fun?”

“Jaywalker” is a manufactured word. Auto industry PR campaigns invented it in the 1920s to move blame for traffic deaths from drivers onto people crossing the street. It worked so damn well the category still shows up in enforcement data a century later.

Most American sidewalks are legally the responsibility of whoever's house they happen to sit in front of. Michael Pollack's new book, Sidewalk Nation, argues this piecemeal ownership is exactly why they're the most contested, and most illegible, infrastructure we have.
