Davis Obst — author of the new book Saving Ourselves from Big Car, and former literary agent best known his work on All the President’s Men — is in good traffic this week.

His career has spanned some of the most pivotal exposés in modern history — from the Pentagon Papers to Watergate. Now, Obst turns his focus to corruption of the American auto lobby.

In the conversation, David traces the deep history of how corporate and political power entrenched car dependence in America — from the invention of jaywalking to the National Highway Act, from leaded gasoline to insurance redlining. He shows how Big Car reshaped American culture, politics, and neighborhoods.

Timeline:

00:00 Introduction.

09:24 Breaking the My Lai massacre, Pentagon Papers, and Watergate.

12:00 The disastrous birth of car culture — and leaded gasoline.

22:00 The deadly toll of lead poisoning and corporate denial.

26:20 Why the U.S. rejected the Paris Accords.

More on David (via the Santa Barbara Independent).

What do Albuquerque, Anchorage, and Albany have in common? Beyond cultural and climate differences, each city — like countless others in the U.S. — has given over about a third of its downtown land to off-street parking.

This week, we reframe the way we talk about infrastructure investment. Rather than citing too few users as a reason not to invest in better infrastructure, what if we saw the folks persisting in spite of lacking infrastructure as a signal and hunger for more?

Timeline:

00:00 A commonality.

02:20 Rethinking how we frame bike and pedestrian infrastructure.

05:20 Bridges, as a proxy.

07:15 Kids biking to school reveals resilience.

08:55 Gen Z wants walkability.

10:20 Nostalgia for walkable places.

12:28 Why verbs (walking, biking) matter more than nouns (suburbs, cities).

13:35 Wrapping up, and next week’s conversation with David Obst.

This week, we spend time on the hype (and the pitfalls) of those endless “top ten cities for ...” lists. They’re catchy, shareable, and often the first thing people see when they think about moving or traveling. But do they actually tell us much about what it’s like to live car-lite or car-free in American cities?

So, instead of telling you our top ten cities to move to, we came up with a different list: five practical protocols to quickly gauge walkability when visiting a new city.

Timeline:

00:00 Why “walkable city” lists are everywhere.

02:00 Columbus named #4 most walkable to visit?!

04:00 Why lists are misleading for people considering a move.

05:00 How I travel: living like a local for 24–48 hours.

06:00 The walk-everywhere test.

06:30 Ads and billboards as local cultural signals.

09:00 Game-day infrastructure and movement patterns.

12:30 Stadium design.

13:00 Travel in both the best and worst seasons.

15:40 Hotel districts vs. neighborhoods.

19:00 The mid-block crosswalk litmus test.

22:00 Culture of drivers in Portland, Minneapolis, Vancouver.

24:00 Why a higher-floor matters.

25:00 Bonus: the airport-to-city connection.

26:30 Wrapping up.

Matt McPheely — developer of the Union House project in Greenville, South Carolina — is in good traffic this week to talk about building flexible housing that helps move a city's workforce closer to jobs, in a city not usually known for experimental cohousing developments.

From navigating zoning codes and neighborhood opposition to designing adaptable homes that work for both single families and roommates, Matt shares on what it takes for small-scale developers to build solutions in places like Greenville.

Miguel Mendoza — founder and director of Nómada Estudio Urbano in Ciudad Juárez — is in good traffic this week for a conversation on tactical urbanism, placemaking, and cross-border design between Mexico and the United States.

From wooden pallet furniture in one of the most violent cities in the world, to Bloomberg Philanthropies–supported park and street projects, Miguel’s work in Ciudad Juárez and El Paso shows how small-scale public space interventions can improve safety, foster community engagement, while maintaining a city’s cultural identity.

We also look at how culture shapes design choices, why early childhood spaces can unite neighborhoods and political discourse, and what cities can learn from each other across the border.

Burhan Azeem — the youngest Cambridge City Councilor ever elected — is in good traffic this week for a dive on effective local politics, building bike infrastructure quickly in the states, and being elected to office at 24.

The city — home of Harvard and MIT — is getting a ton done, and fast. Burhan's work focuses on housing, transit, and actually completing ambitious infrastructure projects for his Cambridge constituents (outcomes > process).

Sophie McAdara — Programs and Operations Manager for Bring It Home, and former City of Bentonville urban planner — is in good traffic this week to discuss just what the heck is going on down in Northwest Arkansas. Bentonville, and neighboring towns, have been part of a regional boom in recent years. National attention has followed, and much praise has been given.

From mountain bike lanes alongside local roads, to robust greenway projects, and urban integration with natural surroundings, the area has begun to foster a unique identity.

Walmart, the University of Arkansas, and others have invested significantly in the livability of the region.

This week, we discuss the potency of urbanism's gateway drug: summer festivals. Culturally, Americans love to frequent farmer's markets, watch fireworks, and attend live arts shows in the park. We often don't realize that these are all functions of a walkable environment (even if often temporary).

Vendor tents are proxies for small shops, food trucks could be permanent neighborhood eateries, and running into friends could be a norm rather than a novelty.

Instead of closing a parking lot or street for one night only, what if we planned our cities to facilitate and prioritize community all year long?
