75 Safety Rules Assumed a Steering Wheel. The Government Has Updated 16.

Every vehicle sold in America must comply with 75 Federal Motor Vehicle Safety Standards. All were written assuming a human driver. Since 2022, NHTSA has updated 16. Fifty-nine still presuppose a driver who doesn't exist.

Seventy-five. That is how many active Federal Motor Vehicle Safety Standards sit in 49 CFR Part 571, Subpart B, the rulebook every car sold in America must obey. FMVSS No. 101 requires controls and displays "visible to a seated driver." No. 305 governs electric vehicle battery integrity. Between them: 59 years of regulation built on a single load-bearing assumption. Every car has a steering wheel, a brake pedal, and a person operating both.

On March 16, 2026, NHTSA published two proposed rulemakings to amend three of those standards for vehicles with automated driving systems. Combined with a 2022 final rule that updated 13 crashworthiness standards, federal regulators have now touched 16 of 75 FMVSS. At this pace, full accommodation of driverless vehicles arrives around 2038.

What Changed, and When

NHTSA's rewrite has two phases. Phase one, completed March 2022, was the heavy lift: 13 crashworthiness FMVSS (200-series) rewritten to accommodate vehicles without traditional driver seating. FMVSS No. 208, governing airbags and occupant protection, required over 15,000 words of new regulatory text. That rule also introduced a definition of "manually operated driving controls" that now ripples through every subsequent amendment.

Phase two launched March 16, 2026, targeting three crash avoidance standards (100-series). FMVSS No. 102 (transmission shift sequence) would exempt driverless vehicles from requiring visible shift positions. Nos. 103 and 104 (windshield defrosting and wiping) would exempt them entirely. As Sidley Austin's analysis notes, these proposals are "much more concise" than what Virginia Tech's four-volume study recommended. Simplicity appears strategic: fast rulemakings build momentum.

Fifty-Nine Standards Still Waiting

Here is the count nobody is running. After 16 updates, 59 FMVSS remain untouched. Among them:

FMVSS No. 108 (lamps and reflective devices): 67 pages specifying headlamp aim, turn signal angles, and reflector placement calibrated to a forward-facing driver. NHTSA calls it "much longer and more complex" than anything proposed so far.
No. 111 (rear visibility): requires a rearview image visible to "the driver." A bidirectional vehicle like Zoox's has no "rear."
No. 114 (theft protection): mandates a "key-locking system." A robotaxi dispatched by app has a different threat model.
No. 135 (brake systems): assumes service brakes activated by "a foot control."
No. 126 (electronic stability control): references "driver input" 23 times.

Zoox's Eight-Standard Shortcut

While NHTSA rewrites the rules at federal pace, Amazon's Zoox is asking to skip the line. On August 22, 2025, Zoox petitioned for a temporary exemption from eight FMVSS to deploy up to 2,500 steering-wheel-free robotaxis per year. NHTSA published the petition for comment on March 11, with responses due April 10.

Notice the gap between regulatory tracks. NHTSA's March 2026 rulemaking addresses standards 102, 103, and 104. Zoox needs exemptions from 103, 104, 108, 111, 135, 201, 205, and 208. Overlap: two standards. Zoox requires relief from five FMVSS that formal rulemaking hasn't started to address.

This reveals NHTSA's two-track approach. Track one: changing rules for all manufacturers. Slow, methodical. Track two: individual exemptions under 49 CFR Part 555, capped at 2,500 vehicles per year. Both tracks run simultaneously because neither is fast enough alone.

How Long This Actually Takes

Here is the math nobody publishes. Phase one took four years (2018 ANPRM to 2022 final rule), updating 13 standards: 3.25 per year. Phase two's three proposals may finalize in 12-18 months: roughly 2 per year. Conservatively, 20-30 of the remaining 59 standards contain language explicitly referencing a human driver. At the fast-track pace, that is 10-15 years. Complex standards like No. 108 could individually take 3-5 years.

Blended estimate: a vehicle complying with every FMVSS without individual exemptions is a 2033-2038 proposition. For context, NHTSA's own four-volume study took from 2020 to December 2025 just to analyze the problem.

GM Tried This Before

General Motors petitioned NHTSA in 2019 for an exemption to deploy its Cruise Origin without steering wheels. That petition sat for three years. GM withdrew it in November 2022, filed again, then withdrew a second time in 2024 after Cruise's operational suspension following a pedestrian-dragging incident in San Francisco. Part 555 was designed for specialty vehicles (limousines, armored cars), not a technology transition affecting every automaker.

Limitations

This analysis counts approximately 75 active FMVSS based on the current Code of Federal Regulations. NHTSA does not publish an official total; the exact count depends on how sub-standards are tallied. "16 updated" includes 13 from the 2022 final rule and 3 from the March 2026 NPRMs, which are proposed but not finalized. If those proposals stall, the count remains 13. Our estimate that 20-30 remaining standards need driver-specific amendments rests on keyword analysis, not legal determination of which standards actually prevent driverless deployment.

Why Slow Might Be Right

A strong case exists for NHTSA's deliberate pace. Waymo operates in four cities. Cruise is rebuilding. Zoox has not carried a commercial passenger. U.S. robotaxi fleets number in thousands, not millions. Rewriting 75 standards for a technology at this scale risks locking in design assumptions that will be obsolete before ink dries. NHTSA's 2022 definition of "manually operated driving controls" may already need revision as vehicle architectures evolve. Measured pacing, in this view, is not bureaucratic drag but appropriate caution for rules governing every vehicle sold in America.

But the counterpoint writes itself: when a company must petition for permission to build a car without a windshield wiper motor it will never use, compliance costs have decoupled from safety benefits.

The Bottom Line

Fifty-nine years of car safety rules assumed one thing: somebody is driving. NHTSA has spent four years updating 16 of 75 standards for the possibility that nobody is. Regulatory infrastructure isn't blocking autonomous vehicles because regulators oppose them. It's blocking them because the code was written for a world that is disappearing faster than the code can be rewritten.
