When Tesla started calling its Austin ride-hailing service a robotaxi, the picture it painted was simple: a car that drives itself, no one at the wheel. What the company told a U.S. senator is considerably messier. Tesla is the only autonomous vehicle maker among seven companies that responded to an investigation by Senator Ed Markey, a Democrat from Massachusetts, whose staff has now released those disclosures. And Tesla is the only one whose remote operators can take the wheel directly.
The distinction matters. Six of the seven companies — Waymo, Zoox, Aurora, Motional, May Mobility, and Nuro — told Markey's office their remote workers provide input that the vehicle's software then evaluates and decides whether to use, according to Wired, which first reported the disclosures. The human is an advisor. Tesla's system is different. According to the company's disclosure, signed by Karen Steakley, Tesla's director of public policy, remote assistants are authorized to temporarily assume direct vehicle control at speeds up to 2 mph, or up to 10 mph if the vehicle software permits it. The human is a driver.
Tesla's Austin robotaxi service launched in June 2025 with roughly 50 vehicles. In most of those vehicles today, a human safety operator still sits in the front passenger seat — close enough to take over if the software falters. The remote override capability exists as a backup layer, but it blurs the line between what the company calls autonomy and what it actually deployed.
Markey's inquiry was straightforward: how often do these vehicles need human help? Every company refused to say, according to Markey's office. What they disclosed instead were the mechanics of their assistance programs — enough to reveal the structural gap between how the industry talks about self-driving and what the technology does in practice. "Every autonomous-vehicle company refused to disclose how often their AVs require assistance," Markey said. "They are hiding key information about the true level of autonomy." He called for an investigation by the National Highway Traffic Safety Administration and for federal legislation to require disclosure of remote assistance data.
The senator also flagged a national security dimension. Waymo's remote assistance operation is based partly in the Philippines, according to its disclosure. Markey warned that overseas remote operators could be more susceptible to interference by hostile actors — someone with access to a remote assistance connection, he argued, effectively has driver-like control over a vehicle moving through a city. Waymo, for its part, said its remote workers do not drive the vehicles directly; they provide input the software evaluates, consistent with how the other five non-Tesla companies described their systems.
Remote assistance is not new. Most AV developers use it as a fallback — a human supervisor who can nudge a stuck vehicle or help it navigate an ambiguous situation. The technology has always been sold as a safety net rather than a primary operating model. What the Markey disclosures reveal is that the safety net looks very different depending on the company. At one end, a remote worker suggests a path and the software decides. At the other, a remote worker turns a steering wheel from miles away and the car goes where they're pointing it.
For Tesla, the disclosure sits awkwardly against years of "Full Self-Driving" branding. The feature name implies the car handles everything. What Tesla told Markey is that sometimes a human operator handles it instead — at up to 10 mph. That is not nothing. It is also not what the label says.
The question now is whether the disclosure changes anything regulatorily. Markey wants NHTSA to investigate and Congress to legislate. Neither has moved yet. What the documents do provide is a rare, detailed look at the operational reality behind seven companies' autonomous vehicle programs — and the distance between the marketing and the machine.
