NHTSA Cracks Down: Demands Full Disclosure on Robotaxi Tech & Weather Vulnerabilities

Federal regulators just threw a wrench into the autonomous vehicle gold rush. The National Highway Traffic Safety Administration (NHTSA) is forcing robotaxi operators to reveal exactly how their tech handles—or fails at—adverse weather conditions.

Rain, sleet, and algorithmic panic attacks

Sources confirm the agency wants hard data on sensor performance during storms, emergency protocols when AI gets confused (which happens more than investors would like to admit), and whether these $300,000 taxis-to-nowhere can handle a Midwest pothole.

The fine print they don't want you to see

While CEOs pitch 'weather-agnostic' autonomy, internal documents suggest most systems still rely on fair-weather assumptions. One leaked test video shows a prototype freezing—literally—when confronted with light snow. But hey, at least the blockchain-based payment systems work flawlessly (for now).

This regulatory move could ground entire fleets until 2026—or until VCs find another buzzword to pump. Either way, the 'transportation revolution' just hit its first regulatory speed bump.

NHTSA demands details on robotaxi tech and weather risk

NHTSA has been looking into how Tesla’s Full Self-Driving system performs when visibility on the road is reduced. Since October, the agency has been investigating several crashes involving Tesla vehicles using this system under poor weather conditions, including fog, SUN glare, rain, dust, and snow.

The current probe includes 2.4 million cars already on the road. One of those incidents was a fatal crash in 2023, directly tied to FSD mode being active.

In May, federal regulators demanded that Tesla outline not just how many cars would be involved in its robotaxi service, but also when the technology would become available to drivers outside of Tesla’s direct control.

They also wanted a technical breakdown of how the system detects and handles changes in road visibility. The letter included specific questions about what happens when a car encounters weather that affects visibility mid-trip, and what built-in fail-safes would kick in.

In the documents Tesla submitted to NHTSA, CEO Elon Musk said that the trial program in Austin would focus heavily on safety, and that humans would remotely monitor the robotaxis. But there are no official disclosures yet about how often humans have to intervene during real-world tests or how capable the system is of operating without a driver.

The initial launch in Austin is expected to include just ten cars, each geo-fenced to avoid the city’s toughest routes and intersections. If something goes wrong, teleoperators—remote humans ready to take control—are lined up to jump in. Despite the limited scope, the launch is being seen as a real-world test of Tesla’s self-driving platform, years after it was first promised.

Tesla tech lacks L4 certification as Waymo ramps up

While Tesla pushes forward with its camera-only system, it still hasn’t proven that it can reach Level 4 autonomy, where a car drives itself with no human backup. Its main rival, Waymo, has already rolled out about 1,500 driverless vehicles in four US cities.

Unlike Tesla, Waymo uses expensive lidar and radar sensors stacked on top of its vehicles. Their cars are built on a Jaguar I-Pace platform, with each vehicle priced above $70,000, plus tens of thousands more in added hardware.

Tesla, on the other hand, is betting on the Cybercab, which Musk claims will cost under $30,000. That would undercut rivals by a wide margin. The lower price point is possible because Tesla ditched lidar and radar in favor of a vision-only system. But so far, there’s no proof the setup works at high levels of autonomy. The company also hasn’t revealed how often the cars require manual intervention during testing.

Beyond hardware, there’s another big unknown: how Tesla’s Full Self-Driving software will perform across its existing fleet. Musk has pitched the idea that owners could opt in and allow their cars to operate as part-time robotaxis, creating a decentralized fleet without Tesla owning the vehicles.

But it’s still unclear whether older models will even be compatible with the new software. Owners would also be responsible for maintenance, cleaning, and insurance, which could turn into a logistical nightmare.

Waymo has gone in a different direction, setting up its own charging and maintenance hubs to support its robotaxi fleet. While Tesla wants a lightweight, asset-free approach, that could backfire if vehicle upkeep falls on users.
