NHTSA Proved Its Safety Rules Saved 860,000 Lives. Now It Has to Find 10 to Kill for Every New One.

Sometime in 2024, a researcher at the National Highway Traffic Safety Administration finished a half-century accounting. What it found: Federal Motor Vehicle Safety Standards had prevented more than 860,000 deaths between 1968 and 2019, along with 49 million nonfatal injuries and damage to 65 million vehicles. Seventeen dollars saved for every one dollar spent.^[6] Staggering. NHTSA published those findings with the quiet pride of a bureaucracy that had proven its reason for existing.

Then, on January 23, 2026, that same agency published Docket No. NHTSA-2026-0133: a formal Request for Comment on "Vestigial Vehicle Safety Regulations."^[1] The word choice was deliberate. NHTSA compared its own safety standards to vestigial organs, appendixes and wisdom teeth, structures that "may have served a vital purpose in a previous evolutionary stage" but "no longer serve a functional role and, in some cases, can cause harm." The agency invited the public to nominate which of its rules should be amputated.

What compels this surgery is Executive Order 14192, signed January 31, 2025, which imposes a 10-to-1 repeal ratio on federal agencies: for every new regulation issued, ten existing ones must be identified for removal.^[2] Pair that with EO 14219, which directs agencies to implement the "Department of Government Efficiency Deregulatory Agenda," and the math gets ugly fast. When NHTSA finalized its automatic emergency braking mandate in April 2024, projected to save 360 lives per year, the 10-to-1 framework means the agency now owes ten regulatory scalps for the privilege of requiring a technology that stops cars from hitting pedestrians.^[3]

NHTSA was not idle while the RFC circulated. By May 30, 2025, the agency had already launched 16 deregulatory actions, 15 Notices of Proposed Rulemaking and one withdrawal, targeting standards on seating systems and seat belt anchorages among others.^[4] The January 2026 RFC broadened the hunt, asking commenters to flag any FMVSS requirement that imposes "compliance burdens that do not result in a measurable increase in real-world safety" or that "stifles design creativity."

Consumer Reports, in its formal response, drew a line that NHTSA's own framing blurred: updating a standard to reflect modern technology is a pro-safety action; removing one to cut compliance costs is a purely deregulatory one.^[5] CR did concede that some standards genuinely need revision. FMVSS No. 302, the vehicle flammability standard, still uses a 1971 open-flame test despite the fact that fewer than 10% of vehicle fires start from open flames or smoking materials. A peer-reviewed 2024 study found harmful flame retardants in the interiors of all 101 vehicles tested across 22 brands, chemicals manufacturers add specifically to pass a test that measures the wrong thing. Updating 302 would be good policy; eliminating it would be something else entirely.

But that distinction is exactly what the 10-to-1 ratio erases. A genuine modernization and a raw cost-cutting repeal both count toward the quota. As CR put it, the executive order creates pressure "to find regulations to cut" where "a standard's compliance cost could become a proxy for whether it deserves scrutiny, rather than whether it is still providing a proven safety benefit."

Limitations

NHTSA's 860,000-lives figure covers 1968 through 2019 and relies on counterfactual modeling: how many people would have died without the standards, given observed crash patterns and historical belt usage rates. No uncertainty band is published, and not every FMVSS contributed equally; seat belts and airbags account for the overwhelming share of prevented deaths, while some standards address property damage or minor injuries. Entirely possible that specific, narrow test procedures within the FMVSS catalog have genuinely outlived their usefulness. FMVSS 302's flammability standard is proof of that. But the 10-to-1 framework does not distinguish between pruning dead wood and felling load-bearing walls.

Strongest Case for Deregulation

Automakers have argued for decades that prescriptive hardware requirements, tests specifying exact dummy positions, precise measurement points, and specific impact angles, lock manufacturers into designs that chase a government test rather than real-world crash outcomes. A seat belt anchorage standard written for 1980s steel-unibody sedans may genuinely constrain how an engineer designs a 2026 carbon-fiber monocoque or a vehicle without a steering wheel. If NHTSA replaced hardware-specific tests with performance-based standards (prove the occupant survives, we don't care how), innovation could accelerate. Fair point. It becomes dangerous only when the 10-to-1 ratio transforms a thoughtful modernization process into a body-count exercise in regulatory arithmetic.

What You Should Do

NHTSA's docket is public. You can read every comment submitted to NHTSA-2026-0133 at regulations.gov and search by docket number. If you have technical expertise on any FMVSS, you can submit your own comment. NHTSA's authorization expires September 30, 2026, and your members of Congress will vote on whether and how to reauthorize the agency, including the scope of its rulemaking authority. That vote will determine whether the 10-to-1 framework survives, gets modified, or becomes the permanent arithmetic of vehicle safety in America.
