Drivers using ‘cooperative steering’ more likely to stay engaged: IIHS
A new study from the Insurance Institute for Highway Safety (IIHS) has highlighted the potential benefits to “cooperative steering” automated driving systems in keeping drivers engaged.
The study found that the likelihood a driver will remain engaged when driving with partially automated systems is higher when using “cooperative steering,” in which manual movements to the steering wheel don’t disengage the software, according to the study results shared in a press release on Tuesday. Inversely, those using partially automated systems that turn off when drivers use the steering wheel were less likely to take an active role.
“These results suggest that small differences in system design can nudge drivers toward safer habits,” said David Harkey, IIHS President.
This recent study looked at survey responses from 1,260 owners of vehicles from Ford, General Motors (GM), Nissan/Infiniti, and Tesla, who regularly use their partially automated driving systems.
Drivers who are used to partial automation that switches off when they try to share control over the steering were found to be less willing to steer or put their hands on the wheel in circumstances that required steering adjustments, while systems with some degree of manual steering were more likely to help drivers remain engaged with the road and take an active role when road scenarios demanded it.
Those with cooperative systems were ultimately 36 percent more likely than the others to say they would steer to one side of the travel lane when needed.
Drivers with vehicle systems that did offer shared control were 40 to 48 percent less likely than the others to say they would keep their hands off the wheel in situations that would make most drivers nervous, while two other recent IIHS studies showed that even those warned to remain engaged did not often do so.
Systems that remain on when drivers adjust steering include Ford’s BlueCruise system and Nissan/Infiniti’s ProPILOT Assist system, while both GM’s Super Cruise and Tesla’s Autopilot disengaged from lane-centering upon receiving driver steering inputs. While both the systems from Tesla and Nissan required drivers to keep their hands on the steering wheel, Tesla’s upgraded Supervised Full Self-Driving (FSD) allows some hands-free driving, and so do the aforementioned Ford and GM systems.
“Those are sizable differences,” said Alexandra Mueller, IIHS Research Scientist and Lead Author of the study. “Although there could be many reasons, one plausible explanation is that systems that switch themselves off whenever the driver steers may make drivers less likely to want to intervene, as it’s a pain to reactivate the system again and again.”
“These findings suggest that cooperative steering may have an implicit influence on how willing drivers are to take action when the situation calls for it, regardless of how they think their system is designed,” Mueller added.

Tesla’s Full Self-Driving Supervised and Cybercab unveil
The news comes weeks after Tesla unveiled its Cybercab robotaxi, which is built without a steering wheel, an accelerator, or brake pedals. It also comes in response to the company’s longtime bet on completely autonomous driving, first through the deployment of its FSD Supervised system, which is eventually expected to unlock an unsupervised version that buyers can use in their own vehicles.
While Tesla’s bet on full autonomy will likely come to fruition in future years, discussions about driver engagement have been ongoing, especially as those using Supervised FSD and other partially automated driving systems have used them in unintended ways that weren’t approved by the manufacturers.
At least for now, driver attention remains an important part of the path to full autonomy, until systems become safe enough to be trusted without supervision. Until then, efforts to keep drivers engaged may prove fruitful, and Tesla and others have taken steps to monitor drivers more closely when they use these systems, in order to ensure full engagement and readiness to regain control of the vehicle when needed.

Tesla Cybercab display highlights interior wizardry in the small two-seater
Photos and videos of the production Cybercab were shared in posts on social media platform X.
The Tesla Cybercab is currently on display at the U.S. Department of Transportation in Washington, D.C., and observations of the production vehicle are highlighting some of its notable design details.
Photos and videos of the production Cybercab were shared in posts on social media platform X.
Observers of the Cybercab display unit noted that the two-seat Robotaxi provides unusually generous legroom for a vehicle of its size. Based on the vehicle’s video, the compact two-seater appears to offer more legroom than Tesla’s larger vehicles such as the Model Y, Model X, and Cybertruck.
The Cybercab’s layout allows Tesla to dedicate nearly the entire cabin to passengers. The vehicle is designed without a steering wheel or pedals, which helps maximize interior space.
Footage from the display also highlights the Cybercab’s large center screen, which is positioned prominently in front of the passenger bench. The display appears intended to provide entertainment and ride information while the vehicle operates autonomously.
Images of the vehicle also show an additional camera integrated into the Cybercab’s C-pillar. The extra camera appears to expand the vehicle’s field of view, which would be useful as Tesla works toward fully unsupervised Full Self-Driving.
Tesla engineers have previously explained that the Cybercab was designed to be highly efficient both in manufacturing and in operation. Cybercab Lead Engineer Eric E. stated in 2024 that the Robotaxi would be built with roughly half the number of parts used in a Model 3 sedan.
“Two seats unlocks a lot of opportunity aerodynamically. It also means we cut the part count of Cybercab down by a substantial margin. We’re gonna be delivering a car that has roughly half the parts of Model 3 today,” the Tesla engineer said.
The Tesla engineer also noted that the Cybercab’s cargo area can accommodate multiple golf bags, two carry-on suitcases, and two full-size checked bags. The trunk can also fit certain bicycles and a foldable wheelchair depending on size, which is quite impressive for a small car like the Cybercab.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.
