As Transit Unplugged closes out 2025, host Paul Comfort sits down with David Zipper for a wide-ranging, end-of-year conversation on where public transportation has been — and where it’s headed next.

A senior fellow at the MIT Mobility Initiative and one of the most influential transportation voices writing today, David brings a rare perspective shaped by public service, venture capital, academia, and journalism. He has authored more than 200 articles in outlets including Bloomberg, Vox, and The Atlantic, examining how transportation, technology, and society intersect.

In this episode, Paul and David reflect on the defining trends of 2025 and look ahead to the challenges and opportunities transit agencies will face in 2026. You’ll hear:

1. Why robotaxis at scale may create new congestion and operational challenges for cities
2. The promise — and pitfalls — of the emerging “abundance” framework in transportation policy
3. How ridership patterns have stabilized into a new post-pandemic normal
4. Why mission creep threatens transit agencies from both the political left and right
5. What New York City’s congestion pricing success could mean for other U.S. cities
6. A candid assessment of electric bus deployment and why flexibility matters
7. How AI-powered bus lane enforcement is already improving service reliability
8. Why autonomous rail may be one of the most important sleeper trends in transit
9. The evolving role of micromobility and e-bike share in expanding transit access
10. Why transit’s future depends on staying focused on fast, frequent, reliable service

This is a thoughtful, occasionally provocative discussion that challenges conventional wisdom while staying grounded in real-world operations — and a fitting way to close out a transformative year for the transit industry.
