Self-driving cars may upend transit before cities can build it

Self-driving vehicles have the potential to cut ride costs by 40-50% and eliminate thousands of road deaths

Author Andrew Miller argues that widespread adoption of self-driving vehicles is no longer a distant promise, as Waymo expands into over 15 cities. However, he warns the technology's biggest remaining hurdles are political: liability, labor, and whether cities embrace or resist the shift.

As of 2025, Waymo has rolled out "robotaxi" services in five US cities

The company has been under investigation by the National Highway Traffic Safety Administration following dozens of crashes and incidents that appear to show Waymo vehicles violating traffic laws over the past decade in Phoenix, San Francisco, Los Angeles, Atlanta, and Austin.

As of 2025, self-driving cars continue to be unavailable to consumers

These vehicles rely on radar, cameras, lidar, and advanced AI to process data and make real-time driving decisions. Companies like Waymo and Mercedes-Benz are testing autonomous cars on public roads, but challenges remain, including technical reliability issues, regulatory hurdles, and a lack of consumer trust.

Autonomous vehicles have been confirmed to reduce greenhouse gas emissions

Research indicates that self-driving cars can reduce harmful pollution through lower traffic, decreased parking demand, and optimized driving behavior. These benefits can be enhanced further in smart cities with responsive traffic signals.

LA used to have one of the best mass transit systems in the country

A century ago, Los Angeles had one of the greatest urban transit networks in America. Today, driving in LA traffic can still be faster than taking the train. The city's rail design, which funnels traffic through a single point, fails to support a city with such a spread-out population.

Future self-driving cars may communicate across a closed wireless infrastructure

Current autonomous vehicles collect and analyze their own data through their own hardware and proprietary software. Connecting data from all such cars on a single network will require overcoming challenges related to standardization and security.

Artificial intelligence may further enhance smart city data analysis

Identifying patterns within systems in the Internet of Things may enable AI tools to make informed decisions regarding transportation, safety, and sustainability without human intervention. However, such tools will also need to successfully address concerns about privacy, digital equity, and algorithmic bias.

Dubai and Barcelona are examples of smart cities

By integrating technology into public transit, utilities, and other municipal systems, these cities aim to reduce costs and enhance the quality of life for their residents. Some of these technologies include adaptive lighting, parking sensors, and underground waste systems.

Hear about the debate over free public transportation

Free public transit boosts economic opportunity and social mobility and is better for the environment. So why do we charge for it? Opponents of free transit cite revenue losses threatening service quality and data showing that free fares don't translate into reduced car use.

Tesla offers two variations of autopilot systems for its vehicles

The standard package provides adaptive cruise control, which adjusts the vehicle's speed according to traffic conditions, and autonomous steering to maintain the car's path. The enhanced system includes automated lane changing, parking, traffic light, and stop sign controls.

The 2021 infrastructure law increased transit spending 42%, but may not have produced more transit

The infrastructure bill committed $108B to transit, the largest investment in history. However, three years in, real inflation-adjusted investment has declined. An 84% increase in non-highway spending coincided with a potential 29% decrease in actual structures, most likely due to construction inflation and bureaucratic delays.

Washington DC's streetcar network built the modern American suburb

Washington's first electric streetcar line launched in 1888, and real estate developers quickly built lines to open new neighborhoods. A 35-minute ride from Chevy Chase, Maryland, to downtown Washington transformed farmland into a suburb.

Mass transit in America began with horse-drawn omnibuses in New York City in 1827

The omnibus, a large horse-drawn stagecoach that ran a fixed route and carried a dozen riders at an affordable fare, was different from a private carriage because it carried everyone, not just the wealthy.

Uber's startup origin story starts in Paris

Back in 2009, Uber’s cofounders tried to catch a cab during a Paris snowstorm without much luck. If only they could have requested a ride through one of their phones. This article dives into how Uber went from idea, to reality, to successful startup.

How parking infrastructure reveals a region's values

As cars became more popular, the need for city parking increased. In Europe, well-established cities with limited space generally opted for more expensive underground parking beneath public spaces to preserve aesthetics. Available land and decentralized planning in the US saw more parking lots and garages built. These decisions reveal broader policy realities for these regions.

OpenAI CEO Sam Altman has called OpenAI 'the most capital-intensive startup in history'

As of 2024, Silicon Valley was set to spend $1T in the coming years building AI. As companies, including Google and Microsoft, fling billions at AI dreams, concerns are rising about whether that money will ever be recouped. To learn about the argument that there is an AI bubble—and that it could soon burst if AI doesn't prove its worth—read this article.

How Elon Musk's businesses have shaped Texas' Bastrop County

After deadly wildfires in 2011 burned a significant portion of the county, the tech boom in Austin pushed development eastward. Elon Musk has since made the region a key hub of his businesses, including a Tesla gigafactory considered one of the largest factories in the world by volume. Watch this reporter visit the town to hear the pros and cons of the transformation.

As both rent prices and mortgage rates rise across the US, many companies have simultaneously continued operating hybrid or remote workforces post-pandemic. A podcast episode dives into why city dwellers aren't all living in their prepandemic break rooms just yet.

Why decarbonizing the entire electric grid is impossible with its current infrastructure

Fossil fuel plants can be built anywhere and have thus typically been built near highly populated areas, such as coastal cities, where electricity demand is high. However, certain renewable resources operate most efficiently in specific regions, such as wind turbines in the Midwest, and therefore require substantial transmission infrastructure to be constructed to transport the generated electricity.
