When a Waymo froze in the middle of an officer’s response to a mass shooting earlier this year, the fix wasn’t complicated. An officer walked up, opened the door, sat down, and drove the car out of the way. The same thing happened in June. An officer had to reposition a stalled Waymo blocking the road to a natural gas explosion at an apartment building. Both times, the fallback worked for one boring reason: the steering wheel requirement meant the car still had a seat, a wheel, and pedals for a human to use.
That detail is about to stop being true.
On July 8, NHTSA Administrator Jonathan Morrison sent a public letter to every driverless developer operating in the United States. The agency says it has documented a repeated pattern of autonomous vehicles driving into active emergency scenes. These vehicles have blocked ambulances and fire crews, and failed to react to flares, smoke, cones, and flashing lights. NHTSA wants developers in a room by the end of the month to explain their fixes. Coverage of the letter has focused on the enforcement gap, and rightly so. But buried in the same news cycle is a second decision from the same agency: quietly dropping the steering wheel requirement. That decision makes the emergency-scene problem much harder to solve in hardware terms, not easier.
The Brake Pedal Nobody Mentioned
Two weeks before the first-responder letter, on June 25, NHTSA quietly began rulemaking. The goal: eliminate the federal requirement for a manual brake pedal in vehicles designed never to be operated by a human. Stopping-distance requirements stay in place. Steering wheels, mirrors, sun visors, and defrosting systems are all going through the same process, one FMVSS section at a time. In effect, the steering wheel requirement is next on that list. The agency frames this as cleanup, tearing out equipment mandates written when nobody imagined a car without a driver.
Here is the part worth sitting with. Every documented case of a police officer rescuing a confused robotaxi from an emergency scene has depended on that exact equipment being there. Waymo built its fleet on the Jaguar I-PACE platform, which rolled off the line with a full driver’s console because Jaguar builds it for human buyers too. Nobody sits in that seat during a normal ride. But when a car freezes in traffic, that seat is the entire rescue plan.
What Happens When the Steering Wheel Requirement Disappears
Waymo’s borrowed hardware is already the exception, not the future. Tesla unveiled its Cyberab with no steering wheel and no pedals at all — a design choice the company has never walked back. Zoox built its shuttle the same way from its first prototype: a symmetrical box with no driver’s position to speak of. Both companies have been moving through NHTSA’s Automated Vehicle Exemption Program and Part 555 exemption process. The agency has spent the past year streamlining that process specifically so vehicles like these can reach public roads without a case-by-case waiver fight.
Put those two facts next to each other. The agency is simultaneously telling AV companies to get better at recognizing firefighters. At the same time, it’s clearing the regulatory path for vehicles that no firefighter, officer, or paramedic could physically drive even in an emergency. When one of these fails to yield to an ambulance, the person standing next to it will have no pedal to press and no wheel to turn. The only options left are a phone call to a remote operator or a flatbed tow truck. Neither one clears an intersection in the next ten seconds, which is usually what the moment actually requires.
The Remote Operator Is Not a Real-Time Backup
Robotaxi companies will point out that a human is never fully out of the loop. Remote assistance centers exist at Waymo, Zoox, and every serious AV operator. They’re staffed by people who can review a stuck vehicle’s sensor feed and approve a path forward. What that job rarely includes is live steering, the exact task the old steering wheel requirement assumed a human would always be ready for.
Cellular latency is the culprit. It takes seconds for video and lidar data to reach a monitor, and seconds more for a decision to travel back to the vehicle. That makes real-time remote driving impractical for anything faster than a crawl. Remote operators mostly confirm a route the car already proposed. That works fine for a vehicle paused at a weird construction cone. It is a much shakier plan for a vehicle sitting in the middle of an active fire scene. Smoke cuts visibility, and a truck is trying to get past it.
Whose Insurance Covers the Officer Who Drives Your Robotaxi
The current workaround creates its own tangle nobody has litigated yet. When an officer gets behind the wheel of a robotaxi that isn’t his and drives it out of the way, something shifts. For a few seconds, he becomes the operator of a vehicle a corporation owns and insures under a commercial fleet policy he has no relationship with. If that car clips a mailbox, or worse, rolls forward into the exact scene it was blocking, a real question follows. Whose insurance pays, and whose liability attaches? Neither has a settled precedent. It has simply never come up outside a handful of documented incidents. Remove the wheel, and the question doesn’t disappear. Instead, a longer, more dangerous gap replaces it. Nobody can move the car at all, so it sits there until a tow arrives.
A Pattern Bigger Than One Letter
This is the second time in two months NHTSA has had to publicly correct course on Waymo specifically. That follows an open investigation into robotaxis illegally passing stopped school buses. It also lands the same week as new reporting on Stellantis, Wayve, and Uber’s robotaxi ambitions. And it follows years of harder lessons, including GM’s decision to gut its Cruise robotaxi division after years of losses. Different teams on different clocks are writing the industry’s hardware roadmap and its safety roadmap. The emergency-scene letter is what happens when those two clocks fall out of sync in public.
Morrison’s letter puts it plainly: “public trust on our roads is earned, not given.” That line was aimed at software behavior. It applies just as well to the steering wheel requirement NHTSA quietly rolled back. It applies just as well to the hardware decision NHTSA made two weeks earlier and never mentioned in the same breath.
What the Steering Wheel Requirement Means for You
None of this means driverless cars should have kept their steering wheels forever out of caution. Removing equipment nobody uses is a legitimate engineering decision. NHTSA is right that a lot of Federal Motor Vehicle Safety Standards assumed a car that always has a driver in it. The mistake is sequencing. Deleting the steering wheel requirement before the software can reliably handle the scenarios that requirement was quietly fixing is not deregulation. It is subtraction without a replacement.
The steering wheel in a Waymo was never really there for the passenger. For a few seconds on a handful of nights this year, it was there for the cop.
