Houston Strategies

The Economist on how America's car dependence makes the country fairer and more efficient

The Economist magazine has a fantastic article (no-paywall link) on the upside of America's focus on cars for mobility - and I would argue Houston is at the pinnacle in America for major metros. The whole thing is great, but here are the best excerpts (highlights mine): 

In praise of America’s car addiction

How vehicle-dependence makes the country fairer and more efficient

...It seems a classic case of elite opinions (cars and suburbs are awful) diverging from mass preferences (people quite enjoy them). For many, the main attractions of suburbia are lower housing costs and greater safety. Yet recent research sheds light on how cars are a crucial part of the equation, making America’s suburbs both impressively efficient and equitable.

...

Start with convenience. It is well-known that American cities are configured for vehicles, a process that began in the 1920s with the Model T. Car-centric urban designs became dominant throughout the country, involving wide roads, ample access to expressways and parking galore. To varying degrees, other countries have copied that model. Yet America has come closest to perfecting it. In a paper released in August, supported by the World Bank, a group of economists examined road speeds in 152 countries. Unsurprisingly, wealthy countries outpace poor ones. And within the rich world, America is streets ahead: its traffic is about 27% faster than that of other members of the OECD club of mostly rich countries. Of the 20 fastest cities in the world, 19 are in America.

...

Driving speed shrinks distance. One fashionable concept among urban planners these days is the “15-minute city”, the goal of building neighbourhoods that let people get to work, school and recreation within 15 minutes by foot or bike. Many Americans may simply fail to see the need for this innovation, for they already live in 15-minute cities, so long, that is, as they get around by car. Most of the essentials—groceries, school, restaurants, parks, doctors and more—are a quick drive away for suburbanites.

The car’s ubiquity has another rarely appreciated benefit. A recent study by Lucas Conwell of Yale University and colleagues examined urban regions in America and Europe. They calculated “accessibility zones”, defined as the area from which city centres can be readily reached. Although European cities have better public transport, American cities are on the whole more accessible. Consider the size of accessibility zones 15-30 minutes from city centres. If using public transport, the average is 34 square kilometres in America versus 63 square kilometres in Europe. If using private cars, the difference is much starker: 1,160 square kilometres in America versus 430 square kilometres in Europe.

...it is precisely such accessibility that has put larger homes and quieter streets within reach for a remarkably wide cross-section of the country. In his analysis of the census from 2020, William Frey of the Brookings Institution, a think-tank, showed that suburbia has become far more diverse over the years. In 1990 roughly 20% of suburbanites were non-white. That rose to 30% in 2000 and 45% in 2020.

Not that cars are a panacea. Owning or renting one costs plenty of money, and is an especially big burden for the working poor. It is therefore common to hear laments in American cities about the sorry state of mass transit. Yet this general perception, though widespread, is not entirely accurate. Even if primarily built for private cars, roads are a shared resource and can be viewed as the “tracks” for buses. In their study Mr Conwell and his colleagues conclude that bus-based transportation in America is surprisingly effective: public-transit options between distant suburbia and city centres are roughly comparable in America and Europe. Although America could do more to improve its bus services within its urban cores, the crucial point is that cities designed for cars can also support mass transit.
