Once again, the National Highway Traffic Safety Administration (NHTSA) is requesting more information from Tesla regarding the safety of Autopilot.
In a special order dated July 26, the regulator shared concerns about a change to Tesla’s advanced driver assistance system that allows drivers to use the system for extended periods of time without prompting the driver to place their hands on the steering wheel.
NHTSA ordered Tesla to answer questions and produce documents, according to the letter released Tuesday.
The special order is part of NHTSA’s ongoing investigations into Autopilot after identifying more than a dozen crashes in which Tesla vehicles hit parked emergency vehicles. The agency is also actively looking into whether Teslas can make sure drivers are paying attention when using Autopilot.
This isn’t the first time NHTSA has requested information about Tesla’s driver monitoring systems (DMS), which are meant to ensure drivers are paying attention to the road while automated driving systems are engaged. In August 2022, the agency asked Tesla to answer questions about its cabin camera as part of an ongoing probe into 830,000 Teslas that include Autopilot. Tesla says the camera is built with a DMS that can determine if a driver isn’t paying attention and send them noise alerts.
Tesla previously relied on a system that could detect when a driver’s hands were on the steering wheel, but introduced the camera-based DMS in May 2021.
NHTSA asked for more information about the DMS in July, as well as information on how Tesla generates its quarterly safety reports.
“The resulting relaxation of controls designed to ensure that the driver remained engaged in the dynamic driving task could lead to greater driver inattention and failure of the driver to properly supervise Autopilot,” reads NHTSA’s July letter to Tesla.
Tesla CEO Elon Musk has shared plans on X — the social media platform formerly known as Twitter that Musk bought in 2022 — to gradually reduce alerts aimed at ensuring drivers using Tesla’s “Full Self-Driving” (FSD) system keep their hands on the wheel.
The National Highway Traffic Safety Administration (NHTSA) has once again requested more information from Tesla regarding the safety of its Autopilot system. In a special order dated July 26, the regulator expressed concerns about a change to Tesla’s advanced driver assistance system that allows drivers to use the system for extended periods without having to place their hands on the steering wheel. NHTSA has ordered Tesla to answer questions and produce documents as part of its ongoing investigations into Autopilot, which have been prompted by a series of crashes involving Tesla vehicles hitting parked emergency vehicles. The agency is also looking into whether Teslas ensure drivers are paying attention when using Autopilot. This is not the first time NHTSA has requested information about Tesla’s driver monitoring systems, as it previously asked the company to answer questions about its cabin camera. Tesla has been ordered to provide information on the software update, including when it was introduced, how many vehicles were affected, Tesla’s reason for installing it, and any plans to enable the software in the next year. Tesla has until August 25 to respond, and late responses can result in penalties. These developments come as Tesla faces back-to-back lawsuits related to Autopilot incidents. One lawsuit alleges that Autopilot caused a vehicle to veer off a highway, resulting in a fatal crash, while another lawsuit concerns the death of a driver whose Tesla Model 3 collided with a truck.
