For over a century, American and European cities have been shaped around the automobile — with highways cutting through neighborhoods, parking consuming vast swaths of urban land, and street design prioritizing vehicle throughput over human safety and experience. A growing movement of urban planners, advocates, and policymakers is pushing back — with congestion pricing, protected bike lanes, pedestrianized streets, and fifteen-minute neighborhood concepts gaining traction in cities from Oslo to Paris to New York. But car culture runs deep, suburban infrastructure is already built, and the politics of mobility are notoriously brutal. Is the movement to redesign cities around people finally at a tipping point — or perpetually fighting uphill?

Context

The stakes of urban design choices are far higher than convenience or aesthetics. Transportation accounts for approximately 29% of U.S. greenhouse gas emissions — making how cities are designed inseparable from climate action. Traffic deaths kill 1.35 million people annually worldwide — a toll that human-centered design could dramatically reduce. And the economic costs of car dependence — in infrastructure maintenance, healthcare, lost productivity, and land consumption — are enormous but largely invisible because they are socialized rather than borne directly by drivers. Against this backdrop, the question of whether cities can transition away from car dependence is not just urban planning trivia — it is one of the most consequential design challenges of the century.

Perspective: Janette Sadik-Khan

Janette Sadik-Khan, former NYC Transportation Commissioner and author of Streetfight, is perhaps the most celebrated practitioner of urban transformation — having overseen the conversion of Broadway through Times Square into a pedestrian plaza, the installation of hundreds of miles of bike lanes, and the launch of Citi Bike during her tenure. Her perspective is grounded in hard-won political and operational experience: "The great myth about urban transportation change is that the politics are impossible. They're not. They're difficult — but when you show people what streets can be, when they actually experience a car-free plaza or a protected bike lane, public opinion shifts faster than anyone expects."

Sadik-Khan argues that the key to political success is speed: "Don't spend five years planning — build it quickly with paint and temporary materials, let people experience it, measure the results, then make it permanent. Evidence beats ideology in transportation politics when you can actually show people the data." She points to the dramatic success of Paris under Mayor Hidalgo — which has removed thousands of parking spaces, pedestrianized the Seine riverbanks, and built 1,000 km of bike lanes — as proof that bold political leadership combined with rapid implementation can transform car-dependent cities faster than critics believe possible.

Perspective: Donald Shoup

Donald Shoup, UCLA urban planning professor and author of The High Cost of Free Parking, has spent four decades making perhaps the most important single contribution to the urban reform movement by illuminating how parking requirements shape — and distort — cities. "The single most important thing most cities could do to become more human-centered is eliminate minimum parking requirements," he argues. "When you require every building to provide a certain amount of free parking, you make car use artificially cheap, consume enormous amounts of urban land, make buildings more expensive, and design cities that work only if you drive."

Shoup's analysis reveals that free parking is not actually free — its costs are hidden in higher prices for goods and services, embedded in construction costs, and externalized onto the broader community. "When people say they want free parking, what they mean is they want someone else to pay for their parking. The solution is transparent pricing — charge market rates for curb parking, use the revenue for neighborhood improvements, and let the market allocate space efficiently." He argues that parking reform is politically achievable because it is fiscally beneficial for municipalities and local businesses — even as it gradually shifts the economics of urban transportation in favor of walking, cycling, and transit.

Perspective: Jeff Speck

Jeff Speck, city planner and author of Walkable City, focuses on the comprehensive conditions that make urban transformation succeed or fail — arguing that piecemeal interventions rarely achieve lasting change without addressing the full ecosystem of walkability, transit, and land use. "You can build all the bike lanes you want, but if the land use doesn't support walking — if the destinations are spread too far apart, if the ground floors of buildings are blank walls and parking garages — the streets will still feel empty and unsafe," he argues.

Speck is optimistic about the direction of the movement but realistic about its pace and the magnitude of the opposition. "Car culture isn't just a preference — it's an infrastructure lock-in. Decades of investment in highways, parking, and suburban development patterns have created places that physically cannot function without cars, regardless of what individuals want. Changing that requires not just redesigning streets but reforming zoning, investing in transit, and building political coalitions that can sustain change over the decades required to actually transform built environments."

He is particularly concerned about equity in the urban transformation movement — noting that progressive cities' enthusiasm for bike lanes and pedestrianization can displace lower-income residents while making neighborhoods more desirable and expensive. "The goal isn't just walkable cities for the wealthy — it's sustainable, affordable mobility for everyone. That requires linking transportation reform to housing policy in ways that most cities are not yet doing adequately."

Editorial Synthesis

Where Experts Agree

All three experts agree that the current trajectory of car-dependent urban development is unsustainable — environmentally, economically, and in terms of human health and well-being. There is consensus that successful urban transformation requires political will, speed, and evidence-based advocacy — and that the politics, while difficult, are not impossible. All acknowledge that pricing and incentive structures — particularly around parking — are central levers that current policy largely ignores.

Where Experts Disagree

Sadik-Khan emphasizes rapid implementation and political boldness as the primary requirements for success. Shoup focuses most specifically on parking policy reform as the highest-leverage intervention. Speck insists on the importance of comprehensive, systems-level thinking that connects transportation, land use, housing, and equity — and is most concerned about the risk of displacement accompanying urban transformation. The experts also differ on how quickly urban transformation can realistically occur at scale.

Why This Matters

The question of whether cities can be redesigned around people matters for climate, public health, economic productivity, equity, and the fundamental quality of human life in urban environments. The built environment shapes how people move, whether they exercise, how much pollution they breathe, how much time they spend with family, and whether they feel safe and connected in their communities — making urban design one of the highest-leverage policy domains available to governments at every level.

The evidence from cities that have committed to transformation — Oslo, Amsterdam, Paris, Bogotá — suggests that change is possible and the benefits are real. The challenge is building the political coalitions, institutional capacity, and sustained commitment needed to overcome the enormous inertia of existing infrastructure and the powerful interests that benefit from keeping things as they are.
