In 1965, consumer advocate Ralph Nader released 'Unsafe At Any Speed,' a scandalous exposé on the risks of cars, prompting backlash from leading automakers including General Motors, which gave way to some of the earliest automobile regulations.

NASCAR shifted to a safety-first culture and in 2002 opened a research and development center to focus on safety innovation. No driver has died in NASCAR’s top three series since Earnhardt’s death.

When Michael Waltrip crossed the finish line at the 2001 Daytona 500, it was his first win. But the celebrations quickly turned to sorrow when everyone learned that Dale Earnhardt Sr. had died in a final-lap crash. Within eight months after the collision, nearly every driver wore head-and-neck restraints before a mandate took effect.

This documentary argues that GM systematically bought up and destroyed streetcar networks across the US in the 1930s, replacing them with buses and helping put the automobile at the center of American culture.

This page provides answers to questions on topics ranging from liability for crashes involving autonomous cars to the safety benefits of these cars. A timeline of the evolution of automated safety technologies is also provided.

Almost three decades after Rachel Carson’s “Silent Spring,” a “60 Minutes” segment on the use of Alar, a chemical sprayed on apples, drew national attention and inspired supermarkets and schools to remove apples from their shelves and cafeterias. That same year, the Environmental Protection Agency took action against the use of the chemical in food.

The 1962 book warned against the use of DDT, a pesticide often sprayed over fields of crops, cautioning that it could be harmful if ingested in excessive amounts by humans. Some credit Carson’s book with inspiring the modern environmental movement and with encouraging the US to establish the Environmental Protection Agency in 1970 and ban the domestic sale of DDT in 1972.

The first generation of NASCAR automobiles were nearly identical to on-the-street models, with no modifications allowed to the body or frame. They even raced with doors. Fast-forward 75 years and the cars are 670-horsepower machines designed for racing.

Modern American auto racing began in the 1920s with bootleggers modifying cars to outrun authorities. World War II innovations like better engines and surplus parts fueled post-war racing. By 1947, Bill France Sr. founded NASCAR, creating a unified league with consistent rules, transforming stock car racing into one of America’s favorite sports.

Following the death of Dale Earnhardt Sr. in 2001, NASCAR changed its culture to be safety-first. Part of its changes were to install barriers along tracks that would help absorb the majority of g-forces in a crash. This Daily Downforce article walks through the history of the SAFER barriers, why NASCAR originally chose concrete, and how much of the tracks are covered today.

Before founding the Ford Motor Company, Henry Ford started two businesses that ultimately failed because he didn't get a product to market quickly enough. The Henry Ford Company pushed Henry Ford out in 1902, only to later reform and be renamed after the founder of Detroit, Antoine de la Mothe Cadillac.

In 1904, Henry Ford raced the "999" across a frozen lake and reached an average speed of more than 90 miles per hour, beating the then-record for fastest land speed. Ford's success attracted the eyes of the earliest investors in the Henry Ford Company, Ford's company before he started Ford Motor Company.

To pursue his goal of marrying industry with agriculture, among other reasons, the automobile giant oversaw the design and creation of a vehicle with 12 panels made from plastic. At 2,000 pounds, the car was much lighter than all-steel ones, but production stopped during World War II.

In 1971, the Supreme Court ruled against the government's attempt to block The New York Times and The Washington Post from publishing classified documents on the Vietnam War, delivering a landmark victory for press freedom.

Her 1962 book, “Silent Spring,” inspired many people to consider the chemicals used to grow their food, but Carson didn’t think that manufactured fertilizers needed to be banned from farming, writing that “The ultimate answer is to use less toxic chemicals so that the public hazard from their misuse is greatly reduced.” When she testified to Congress in 1963, she said, “I think chemicals do have a place.”

When Prohibition made alcohol illegal in 1920, it didn’t stop Americans from making and consuming it. The law drove the practice underground. Runners risked their lives to deliver moonshine and began racing among themselves.

The first three decades of Formula 1 saw 41 drivers die in competition; since 1980, only 11 have perished. The reduction is due, in large part, to better safety measures. This article highlights every safety improvement made by year since F1 started, and describes the accidents or deaths that led to the rule changes.

The Nobel Laureate served on the Rogers Commission investigating Challenger, famously demonstrating O-ring failure with ice water and eventually criticizing NASA's culture of risk normalization and management pressure in the final report.

Preceding car infotainment centers by decades, the technology that was unveiled in the Buick elicited praise from auto journalists, but consumers did not make investments in the cars.

In August 1974, following a unanimous Supreme Court ruling, the White House released the "smoking gun" tape—revealing Nixon's role in the cover-up. Watch the CBS News report from Aug. 5, 1974, detailing the fallout from the release of the tapes.

While a 1985 Nature study revealing the Antarctic ozone hole jolted public concern, Reagan's administration was more focused on the Cold War than on environmental policy. His health scare and the market potential for developing alternatives to chlorofluorocarbons helped turn the tide, leading to the Montreal Protocol's unanimous ratification by a bipartisan Senate in 1988.

Faced with the 1973 Arab oil embargo, the U.S. responded with bold innovation—enacting a 55 mph speed limit, pioneering daylight saving time, boosting solar research, expanding nuclear power, and pushing energy-efficient building designs and automotive technologies

Americans initially rejected Ford's September 1974 pardon of Nixon—38% approved it versus 53% disapproved—but by 1986, a slim majority (54%) believed it was the right call, showing that public sentiment softened over more than a decade after the controversy.

On Oct. 20, 1973, President Nixon ordered the firing of Special Prosecutor Archibald Cox—prompting the resignations of Attorney General Elliot Richardson and Deputy AG William Ruckelshaus. This NBC News Special Report shows the immediate aftermath of the decision.

Safety was the leading consumer fear, with technological malfunctions coming in second. Nearly half of all consumers identified skepticism or concern as their primary descriptor for autonomous cars, but 20% cited enhanced mobility for the elderly and people with disabilities as a key benefit.

The 1964 case arose when an Alabama official sued The New York Times over a civil rights advertisement he claimed was defamatory. The ruling makes it very difficult for public officials to win libel suits against the press unless they can prove deliberate falsehood.

Although cars existed before the Model T, manufacturing them required a group of highly specialized mechanics. The Model T was so affordable in large part because of the moving assembly line, which cut down the total manufacturing time of the car and replaced specialized workers with general laborers who performed repetitive tasks.
