Juan Pablo Garnham — Communications and Policy Engagement Manager at the ⁠Princeton Eviction Lab⁠ — is in good traffic this week for a conversation about the hidden scale of America's eviction crisis and why the data didn't exist until recently. Before 2018, there was no way to answer a simple question: how many evictions happen in the United States each year? The lab, founded by Matthew Desmond after winning the Pulitzer Prize for Evicted, set out to change that — and in doing so, revealed eviction not as a symptom of poverty, but as a cause of it.

Juan Pablo walks through the lab's two core offerings: the ⁠National Eviction Map⁠, which tracks every county from 2000 to 2018, and the ⁠Eviction Tracking System⁠, which monitors over 30 cities and ten states month by month since the pandemic began. He explains why collecting this data remains extraordinarily difficult — most states don't mandate reporting, courts lack technology or willingness to share records — and how the lab works with journalists, policymakers, and advocates to turn raw numbers into impact.

The research is clear: Black and Latino families face eviction at rates several times higher than white families, mothers with young kids are especially vulnerable, and one eviction can trigger a cascade of financial and health consequences that become nearly impossible to escape.

We also touch on: Why eviction data matters for housing policy. How teachers often see the warning signs first. The domino effect of a single financial shock. Car dependency as a hidden eviction risk. Illegal lockouts and 911 call data. Why Portland, New York, and Santiago all taught him something about commuting. What it takes to make technical research accessible and actionable.

As much of the northern U.S. shivers through subzero wind chills, this episode argues that waiting for ideal conditions is exactly what keeps most people from ever establishing durable mobility habits at all.

We touch on the psychology of habit formation, explaining why starting a walking routine during perfect weather in May or September sets you up for abandonment when conditions change. If you can walk in January, February becomes manageable. March feels like a gift. By the time summer arrives, the habit is unshakeable. We draw parallels to gym routines built during breaks that collapse when real schedules resume, and make the pitch that the key to year-round walking isn't willpower — it's starting when it's hard and letting everything else feel easy by comparison.

We also touch on: Why the most walkable cities are often in harsh climates. The social layer of walking with friends in cold weather. How small tasks become accomplishments when the weather is terrible. And, what to expect from the show in 2026.

*Obviously, use good judgement when walking in extreme cold. Be safe out there, and layer up.

WE'RE BACK from our December break. At the end of '25, Kemp Gregory — CEO and co-founder of Renewal — joined good traffic for a conversation about energy infrastructure, the hidden potential of idle oil wells, and why the future of renewable energy storage might already be in the ground. As cities debate electric cars, housing development, and transit expansion, energy remains the crucial constraint — one that demands innovation beyond conventional batteries and solar panels.

Kemp walks us through Renewal's unconventional approach: converting millions of abandoned oil and gas wells into gravity-based energy storage systems. He explains how 30,000-pound weights moving up and down inside existing steel infrastructure can discharge power to the grid when needed and store it when it's cheap. From his early days as a petroleum engineer, to his pivot into clean energy at Stanford, Kemp shares how technical knowledge from fossil fuels is being repurposed for renewable infrastructure — and why working with local drilling crews and engineering firms matters more than reinventing everything from scratch.

We also touch on: Why energy storage is the bottleneck for electrification. The geometry problem of EVs and infrastructure strain. How data centers highlight AI's energy costs. Standing on the shoulders of the oil and gas industry. Why rural Texas and California need the same solutions. The importance of making technical work accessible. Biking at Stanford and burning calories without trying.

Nolan Gray — Senior Director of Legislation and Research at California YIMBY — is in good traffic this week for a discussion on how the state with America’s biggest housing problem has become a national leader in reforming the rules of the built environment. California is often treated as both a cautionary tale and a blueprint — derided for its crises yet envied for its innovation.

Nolan walks us through California’s last decade of housing policy evolution — from failed early bills like SB 827 and SB 50 to seismic wins like SB 79, which legalized mid-rise multifamily housing near transit, and AB 130, which exempted infill housing from certain environmental reviews. He explains how bipartisan coalitions, local data, and a willingness to rethink outdated laws like CEQA have made real change possible.

We also touch on: Why density is environmentalism. The cultural paradox of Los Angeles and car dependence. How Sacramento quietly became California’s model midsized city. The future of transit funding and infill development. Lessons from working across political divides to make housing work. How storytelling and communication shape real policy progress.

Ryan Short — author of the new book The Civic Brand, and founder of place-branding firm Civic Brand — joins the show this week for a discussion on how cities can more meaningfully define their brand. The term has been used and overused in almost every industry imaginable, and yet, Ryan argues the importance of the idea at its root. Particularly, for places.

Through this, we spend time on the lifecycle of a cliché, and how cities of various sizes can and should) go about avoiding becoming one.

The new book zooms in, and surveys places that have done the work around brand intentionally, across the states. It's a great starting spot for folks in and around local government, and citizens alike.

An opinion brief, on defining and messaging urban design's healthcare-equivalent issue.

Democrats are centering the current government shutdown showdown around a salient issue: healthcare. It's a smart framework, as the issue has long been a winner for them, and it benefits large swathes of folks across the political aisle.

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.
