Increasing seat belt use is one of the most effective and least costly ways of reducing the lives lost and injuries incurred on the nation's highways each year, yet about one in four drivers and front-seat passengers continues to ride unbuckled. The Transportation Research Board, in response to a congressional request for a study to examine the potential of in-vehicle technologies to increase belt use, formed a panel of 12 experts having expertise in the areas of automotive engineering, design, and regulation; traffic safety and injury prevention; human factors; survey research methods; economics; and technology education and consumer interest. This panel, named the Committee for the Safety Belt Technology Study, examined the potential benefits of technologies designed to increase belt use, determined how drivers view the acceptability of the technologies, and considered whether legislative or regulatory actions are necessary to enable their installation on passenger vehicles. The National Highway Traffic Safety Administration (NHTSA), the study sponsor, funded and conducted interviews and focus groups of samples of different belt user groups to learn more about the potential effectiveness and acceptability of technologies ranging from seat belt reminder systems to more aggressive interlock systems, and provided the information collected to the study committee. The committee also supplemented its expertise by holding its second meeting in Dearborn, Michigan, where it met in proprietary sessions with several of the major automobile manufacturers, a key supplier, and a small business inventor of a shifter interlock system to learn of planned new seat belt use technologies as well as about company data concerning their effectiveness and acceptability. The committee's findings and recommendations are presented in this five-chapter report.

“Offers a useful reminder of the role of modern science in fundamentally transforming all of our lives.” —President Barack Obama (on Twitter) “An important book.” —Steven Pinker, The New York Times Book Review The surprising and important story of how humans gained what amounts to an extra life, from the bestselling author of How We Got to Now and Where Good Ideas Come From In 1920, at the end of the last major pandemic, global life expectancy was just over forty years. Today, in many parts of the world, human beings can expect to live more than eighty years. As a species we have doubled our life expectancy in just one century. There are few measures of human progress more astonishing than this increased longevity. Extra Life is Steven Johnson’s attempt to understand where that progress came from, telling the epic story of one of humanity’s greatest achievements. How many of those extra years came from vaccines, or the decrease in famines, or seatbelts? What are the forces that now keep us alive longer? Behind each breakthrough lies an inspiring story of cooperative innovation, of brilliant thinkers bolstered by strong systems of public support and collaborative networks, and of dedicated activists fighting for meaningful reform. But for all its focus on positive change, this book is also a reminder that meaningful gaps in life expectancy still exist, and that new threats loom on the horizon, as the COVID-19 pandemic has made clear. How do we avoid decreases in life expectancy as our public health systems face unprecedented challenges? What current technologies or interventions that could reduce the impact of future crises are we somehow ignoring? A study in how meaningful change happens in society, Extra Life celebrates the enduring power of common goals and public resources, and the heroes of public health and medicine too often ignored in popular accounts of our history. This is the sweeping story of a revolution with immense public and personal consequences: the doubling of the human life span.
