NHTSA Tells Robotaxi Operators to Fix Emergency-Scene Failures
· TexaHub · Computer Vision, Regulation & Ethics, AI in Industry
Weeks after proposing to drop brake-pedal rules for driverless cars, NHTSA has given AV developers until the end of July to stop interfering with first responders.
The call to action
On 8 July NHTSA Administrator Jonathan Morrison wrote to autonomous vehicle developers describing "a clear pattern of driverless AVs interfering with law enforcement and other first responders", TechCrunch reported [1]. The failures cited include vehicles driving into active emergency scenes, blocking ambulances and firefighters, and not recognising flashing lights, flares, smoke, fire and traffic cones [1]. Developers are expected to present solutions by the end of July [1].
Morrison rejected the idea that these are rare cases: "Emergency scenes are not rare or extreme 'edge cases.' As such, NHTSA is today issuing a call to action for AV developers and operators to immediately focus their resources on fixing this issue" [1]. The letter does not name a company. TechCrunch says the details suggest it is aimed at robotaxi operators such as Waymo, notes that its own reporting found at least six incidents through March in which first responders had to take control of Waymo vehicles and move them out of traffic, and describes a June case in which an officer moved a Waymo so that crews could reach a natural gas explosion at an apartment building; Waymo declined to comment [1].
Deregulation and scrutiny together
The letter arrives two weeks after NHTSA moved in the opposite direction on vehicle design. Its proposed amendment to FMVSS No. 135, the light-vehicle brake standard, would distinguish between vehicles with and without manual driving controls while keeping stopping-distance requirements for all vehicles, with comments due 30 days after publication [2]. TechCrunch reported that the proposal would remove brake-pedal requirements for vehicles driven exclusively by automated systems, alongside proposals to drop windshield-wiper and tyre-placard requirements, and quoted Morrison saying regulators "have to reimagine our regulatory framework" [3].
Industry is already acting on that direction. On 30 June TechCrunch reported that Tesla has begun testing a production Cybercab with no steering wheel or pedals in Austin, with a safety monitor in the passenger seat [4]. Tesla's system relies on cameras alone, while Waymo uses lidar and radar as well [4].
Why it matters
In our reading, the two actions are consistent rather than contradictory. NHTSA is willing to relax rules written for human drivers, but it is signalling that it will judge driverless systems on behaviour in real traffic, and emergency scenes are a perception problem: recognising flares, cones, smoke and improvised closures that rarely look the same twice. The end-of-July deadline is short for software changes of that kind, so the first responses are likely to be operational, such as remote assistance protocols and geofenced exclusions, rather than new perception models. Whether NHTSA follows the letter with formal investigations or recalls, and how it weighs the record when finalising the brake-standard changes, are the next points to watch.
