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 has opened its first public Tesla Semi Megacharger site in Los Angeles. The station reportedly offers up to 750 kW charging speeds and is open to Tesla Semi customers.

The development was highlighted in a post on social media platform X by the official Tesla Semi account.

Tesla Semi Megachargers

The Los Angeles site seems to be the first public Tesla Semi Megacharger that is not located at a Tesla factory. It is also the third Megacharger site currently visible on Tesla’s map.

The Megacharger system is designed specifically for the Tesla Semi and is capable of delivering extremely high charging speeds to support long-haul trucking operations. Infrastructure such as this will likely play a key role in making the Semi competitive with diesel-powered transport trucks.

Tesla’s progress with the Semi has also drawn attention in recent days after Elon Musk biographer Ashlee Vance shared photos from inside the Tesla Semi factory near Giga Nevada. The images suggested that preparations for higher production volumes may be underway, hinting that a broader ramp of the Tesla Semi’s production indeed be approaching.

New deployment strategies

Tesla has continued expanding its broader charging network through several new strategies aimed at accelerating infrastructure deployment. One of these initiatives is the Supercharger for Business program, which allows third parties to purchase Tesla Supercharger equipment and deploy charging stations while still integrating with Tesla’s network.

The program recently marked a milestone in Alpharetta, Georgia, where the city deployed four 325 kW city-branded Superchargers near the Alpharetta Department of Public Safety on Old Milton Parkway. The chargers support the city’s Tesla Model Y police vehicles while also remaining accessible to the public.

As per a report from EVwire, the project was designed not only to support fleet charging but also to generate economic returns that could offset the city’s investment. Tesla’s Supercharger for Business program has already attracted several participants, including businesses and charging providers such as Suncoast Charging, Pie Safe bakery in Idaho, Francis Energy in Oklahoma, and Wawa convenience stores.

The Boring Company said its Vegas Loop system transported roughly 82,000 passengers during the recent CONEXPO-CON/AGG construction trade show in Las Vegas. The event was held at the Las Vegas Convention Center (LVCC) from March 3-7, 2026. 

The Loop’s feat was highlighted by The Boring Company in a post on its official account on social media platform X.

CONEXPO-CON/AGG 2026

CONEXPO-CON/AGG is one of the largest construction trade shows in North America. This year’s event was quite impressive, attracting more than 140,000 construction professionals from 128 countries across the world.

Considering the number of this year’s attendees, the LVCC Loop seemed to have proven itself to be a very useful transportation solution. A video posted by The Boring Company on its official X account featured attendees expressing their enthusiasm for the underground transport system, with some stating that they would like to see similar tunnels across Las Vegas.

The LVCC Loop is only part of the greater Vegas Loop network, which is actively under construction.

New Vegas Loop extensions

One of the newest additions is a station at the Fontainebleau Las Vegas resort on the Strip. The station is located on level V-1 of the resort’s south valet area, according to a report from the Las Vegas Review-Journal. From the Fontainebleau, passengers can travel free of charge to stations serving the Las Vegas Convention Center, as well as to Loop stations at Encore and Westgate.

The system is also expanding beyond the Strip corridor. In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. These trips include a limited above-ground segment after receiving approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.

The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. The extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station just north of Tropicana Avenue.

Tesla preps to build its most massive Supercharger yet: 400+ V4 stalls

The project will be an expansion of the current Eddie World Supercharger in Yermo, California, and will take place in several stages.

Tesla is preparing to build its most massive Supercharger yet, as it recently submitted plans for an over 400-stall Supercharging station in California, which would dwarf its massive 168-stall location in Lost Hills, California.

The project will be an expansion of the current Eddie World Supercharger in Yermo, California, and will take place in several stages.

The expansion, adjacent to the existing Eddie World Supercharger, which is currently comprised of 22 older V2 and V3 stalls limited to 150 kW, unfolds across six phases.

Construction on Phase 1 begins later this year with 72 V4 stalls. Subsequent stages will progressively add hundreds more, culminating in over 400 next-generation chargers. Site plans label expansive parking arrays across Phases 1–5 along Calico Boulevard, with Phase 6 design still to be determined.

The project was first flagged by MarcoRP, a notable Tesla Supercharger watcher.

Strategically located midway on I-15 between Los Angeles and Las Vegas, the station targets heavy EV traffic on this high-demand corridor.

The surrounding 20-mile stretch already hosts over 200 high-power stalls (including 40 at 250 kW, 120 at 325 kW, and more), plus 96 in nearby Baker—yet bottlenecks persist during peak travel.

In scale, it eclipses all existing Tesla Superchargers. The current record holder, the solar- and Megapack-powered “Project Oasis” in Lost Hills, California, offers 164 stalls. Barstow’s former leader had 120. Eddie World 2 will be more than double that size, cementing Tesla’s dominance in ultra-high-capacity charging.

Tesla finishes its biggest Supercharger ever with 168 stalls

Development blends charging with convenience. Architectural drawings show integrated retail: a 10,100 square foot Cracker Barrel, a 4,300 square foot McDonald’s, a 3,800 square foot convenience store, additional restaurants, drive-thrus, outdoor dining, and lease space.

EV-centric features include pull-through bays for Cybertrucks and trailers, ensuring accessibility for larger vehicles and future Semi trucks.

This phased approach minimizes disruption while scaling capacity. It supports Tesla’s broader vision amid rising EV adoption, Robotaxi corridors, and long-haul needs. Once complete, Eddie World 2 won’t just charge vehicles; it will redefine highway stops, turning a dusty desert exit into a futuristic EV oasis.
