Suburban sprawl and automobiles are rapidly acquiring a reputation as scourges of modern American society, say authors Ted Balaker and Sam Staley.
But of all the myths created by the anti-suburbs culture about sprawl and driving, a few deserve to be reconsidered:
• Americans are not addicted to driving, nor do Europeans have an enlightened culture about public transit — in the United States, automobiles account for about 88 percent of travel, in Europe, the figure is about 78 percent, and they are gaining on us.
• Public transit does not reduce traffic congestion; even if the nation’s transit system tripled in size and filled up with riders; according to Anthony Downs of the Brookings Institution, it would not notably reduce rush-hour congestion, primarily because transit would continue to account for only a small percentage of commuting trips.
Also:
• Air quality is getting much better, not worse; since 1970 the Environmental Protection Agency (EPA) reports a dramatic decrease in every major pollutant it measures, although driving is increasing by 1 percent to 3 percent each year, average vehicle emissions are dropping about 10 percent annually.
• Most people already live in developed areas, so it’s easy to get the impression that humans are paving over America, yet only 5.4 percent of U.S. land is developed, further, while house size has increased between 1970 and 2000, the average lot size shrank from 14,000 square feet to 10,000.
• Driving less will not help combat global warming; even if we reach all Kyoto requirements; Tom M.L. Wigley, chief scientist at the U.S. Center for Atmospheric Research, calculates that the Earth would be only .07 degrees centigrade cooler by 2050.

The Five Myths About Suburbia and Our Car-Happy Culture
By Ted Balaker and Sam Staley
This article was published In January-February 2007 by a number of media outlets including the Washington Post, the Dallas Morning News, The Fresno Bee, The Reason Foundation and others.
They don’t rate up there with cancer and al-Qaeda — at least not yet — but suburban sprawl and automobiles are rapidly acquiring a reputation as scourges of modern American society. Sprawl, goes the typical indictment, devours open space, exacerbates global warming and causes pollution, social alienation and even obesity. And cars are the evil co-conspirator — the driving force, so to speak, behind sprawl.
Yet the anti-suburbs culture has also fostered many myths about sprawl and driving, a few of which deserve to be reconsidered:
1. Americans are addicted to driving.
Actually, Americans aren’t addicted to their cars any more than office workers are addicted to their computers. Both items are merely tools that allow people to accomplish tasks faster and more conveniently. The New York metropolitan area is home to the nation’s most extensive transit system, yet even there it takes transit riders about twice as long as drivers to get to work.
In 1930, the interstate highway system and the rise of suburbia were still decades away, and yet car ownership was already widespread, with three in four households having an automobile. Look at any U.S. city and the car is the dominant mode of travel.
Some claim that Europeans have developed an enlightened alternative. Americans return from London and Paris and tell their friends that everyone gets around by transit. But tourists tend to confine themselves to the central cities. Europeans may enjoy top-notch transit and endure gasoline that costs $5 per gallon, but in fact they don’t drive much less than we do. In the United States, automobiles account for about 88 percent of travel. In Europe, the figure is about 78 percent. And Europeans are gaining on us.
The key factor that affects driving habits isn’t population density, public transit availability, gasoline taxes or even different attitudes. It’s wealth. Europe and the United States are relatively wealthy, but American incomes are 15 to 40 percent higher than those in Western Europe. And as nations such as China and India become wealthier, the portion of their populations that drive cars will grow.
2. Public transit can reduce traffic congestion.
Transit has been on the slide for well more than half a century. Even though spending on public transportation has ballooned to more than seven times its 1960s levels, the percentage of people who use it to get to work fell 63 percent from 1960 to 2000 and now stands at just under 5 percent nationwide. Transit is also decreasing in Europe, down to 16 percent in 2000.
Like auto use, suburbanization is driven by wealth. Workers once left the fields to find better lives in the cities. Today more and more have decided that they can do so in the suburbs. Indeed, commuters are now increasingly likely to travel from one suburb to another or embark upon “reverse” commutes (from the city to the suburbs). Also, most American commuters (52 percent) do not go directly to and from work but stop along the way to pick up kids, drop off dry cleaning, buy a latte or complete some other errand.
We have to be realistic about what transit can accomplish. Suppose we could not only reverse transit’s long slide but also triple the size of the nation’s transit system and fill it with riders. Transportation guru Anthony Downs of the Brookings Institution notes that this enormous feat would be “extremely costly” and, even if it could be done, would not “notably reduce” rush-hour congestion, primarily because transit would continue to account for only a small percentage of commuting trips.
But public transit still has an important role. Millions of Americans rely on it as a primary means of transportation. Transit agencies should focus on serving those who need transit the most: the poor and the handicapped. They should also seek out the niches where they can be most useful, such as express bus service for commuters and high-volume local routes.
Many officials say we should reconfigure the landscape — pack people in more tightly — to make it fit better with a transit-oriented lifestyle. But that would mean increasing density in existing developments by bulldozing the low-density neighborhoods that countless families call home. Single-family houses, malls and shops would have to make way for a stacked-up style of living that most don’t want. And even then the best-case scenario would be replicating New York, where only one in four commuters uses mass transit.
3. We can cut air pollution only if we stop driving.
Polls often show that Americans think that air quality is deteriorating. Yet air is getting much cleaner. We miss it because, while we see more people and more cars, we easily overlook the success of air-quality legislation and new technologies. In April 2004, the Environmental Protection Agency reported that 474 counties in 31 states violated the Clean Air Act. But that doesn’t mean that the air is dirtier. The widely publicized failing air-quality grades were a result of the EPA’s adoption of tougher standards.
Air quality has been improving for a long time. More stringent regulations and better technology have allowed us to achieve what was previously unthinkable: driving more and getting cleaner. Since 1970, driving — total vehicle miles traveled — has increased 155 percent, and yet the EPA reports a dramatic decrease in every major pollutant it measures. Although driving is increasing by 1 to 3 percent each year, average vehicle emissions are dropping about 10 percent annually. Pollution will wane even more as motorists continue to replace older, dirtier cars with newer, cleaner models.
4. We’re paving over America.
How much of the United States is developed? Twenty-five percent? Fifty? Seventy-five? How about 5.4 percent? That’s the Census Bureau’s figure. And even much of that is not exactly crowded: The bureau says that an area is “developed” when it has 30 or more people per square mile.
But most people do live in developed areas, so it’s easy to get the impression that humans have trampled nature. One need only take a cross-country flight and look down, however, to realize that our nation is mostly open space. And there are signs that Mother Nature is gaining ground. After furious tree chopping during America’s early years, forests have made a comeback. The U.S. Forest Service notes that the “total area of forests has been fairly stable since about 1920.” Agricultural innovations have a lot to do with this. Farmers can raise more on less land.
Yes, American houses are getting bigger. From 1970 to 2000, the average size ballooned from 1,500 square feet to 2,260. But this hardly means we’re gobbling up ever more land. U.S. homeowners are using land more efficiently. Between 1970 and 2000, the average lot size shrank from 14,000 square feet to 10,000.
In truth, housing in this country takes up less space than most people realize. If the nation were divided into four-person households and each household had an acre, everyone would fit in an area half the size of Texas. The United States is not coming anywhere close to becoming an “Asphalt Nation,” to use the title of a book by Jane Holtz Kay.
5. We can’t deal with global warming unless we stop driving.
What should be done about global warming? The Kyoto Protocol seeks to get the world to agree to burn less fossil fuel and emit less carbon dioxide, and much of that involves driving less. But even disregarding the treaty’s economic costs, Kyoto’s environmental impact would be slight. Tom M.L. Wigley, chief scientist at the U.S. Center for Atmospheric Research, calculates that even if every nation met its obligation to reduce greenhouse gas, the Earth would be only .07 degrees centigrade cooler by 2050.
Wigley favors a much more stringent plan than Kyoto, but such restrictions would severely restrict economic growth, particularly in the developing world. Nations such as China and India were excluded from the Kyoto Protocol; yet if we’re serious about reversing global warming by driving less, the developing world will have to be included.
The United Nations’ Intergovernmental Panel on Climate Change notes that during the 20th century the Earth’s temperature rose by 0.6 degrees centigrade and — depending on which of the many climate models turn out to be closest to reality — it expects the temperature to rise 1.4 to 5.8 degrees by 2100.
What does the IPCC think the effects of global warming may be? Flooding may increase. Infectious diseases may spread. Heat-related illness and death may increase. Yet as the IPCC notes repeatedly, the severity of such outcomes is enormously uncertain.
On the other hand, there’s great certainty regarding who would be hurt the most: poor people in developing nations, especially those who lack clean, piped water and are thus vulnerable to waterborne disease.
The IPCC points out that the quality of housing in those countries is important because simple measures such as adding screens to windows can help prevent diseases (including malaria, dengue and yellow fever) from entering homes. Fragile transportation systems can also frustrate disaster recovery efforts, as medical personnel are often unable to reach people trapped in flooded areas.
Two ways of dealing with global warming emerge. A more stringent version of Kyoto could be crafted to chase the unprecedented goal of trying to cool the atmosphere of the entire planet. Yet if such efforts resulted in lower economic growth, low-income populations in the United States and developing countries would be less able to protect themselves from the ill effects of extreme heat or other kinds of severe weather.
Alternatively, the focus could be on preventing the negative effects — the disease and death — that global warming might bring. Each year malaria kills 1 million to 3 million people, and one-third of the world’s population is infected with water- or soil-borne parasitic diseases. It may well be that dealing with global warming by building resilience against its possible effects is more productive — and more realistic — than trying to solve the problem by driving our automobiles less.
