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 is building a new UFO-inspired Supercharger in the heart of Alien country

Tesla is planning to build a new UFO-inspired Supercharger in the heart of Alien country — Roswell, New Mexico.

Back in 1947, a crash of debris led to rumors of an alleged crash of a UFO just 75 miles north of Roswell near Corona, New Mexico. The crash was officially noted as the recovery of a military balloon, but over the years, speculation persists that the “flying disc” many saw might have been extraterrestrials trying to make contact with Earth.

As a result of the 1947 crash, Roswell has adopted it and used it as the inspiration for much of its tourism. As Tesla is planning to build a Supercharger in the area, it is using the same sort of inspiration for the location, which will feature just eight charging stalls located under a CyberCanopy.

It was first spotted by MarcoRP, a noted Supercharger permit insider:

Here are some better pictures of the design:

Tesla’s Head of Charging for North America, Max de Zegher, confirmed that the site will be inspired by the events near Roswell in 1947. He noted that Tesla “wants to build a few Superchargers cool enough to be worth of the trip itself.”

This will undoubtedly be one of those locations, and along with the Tesla Drive-in Diner Supercharger in Santa Monica, it seems the company could be moving toward some more unique designs for the future, making the charging experience more fun and interesting for owners:

This Tesla vandal caused thousands in damage, but she was let off the hook: Here’s why

A Tesla vandal in Bloomington, Minnesota, caused $3,200 in damages to a car after keying it. However, the local police department, as well as the owner of the Tesla, let her off the hook.

As a Tesla sat in the parking lot of a Cub Foods grocery store, it was damaged in an act of vandalism that we are unfortunately seeing all too frequently. Police managed to locate the woman responsible for the damage, aiming to hold her responsible for the scrapes she applied to the vehicle.

However, in an act that many might not be able to perform, the owner of the Tesla did not want to pursue any criminal charges. Instead, they just wanted their car fixed.

Police Chief Booker Hodges said (via Minnesota Star Tribune):

“The victim in this case just wanted their car fixed, and they just wanted the suspect to pay for that. Based on the totality of the circumstances here, and along with our core value of being compassionate, this is the best outcome for everybody involved in this case.”

It was an incredible act of forgiveness, as many of those who have had their Teslas damaged in response to CEO Elon Musk likely would not have been able to do the same thing. One person who had their vehicle keyed filed a civil lawsuit against the vandal, who damaged their car while it was parked at Dallas-Fort Worth International Airport, seeking $1 million in damages.

Chief Hodges finished his remarks about this specific situation by calling out the leaders who have spread a hateful narrative about Musk and Tesla, and the company’s vehicle owners as well:

“We need our leaders to start leading and stop feeding this rhetoric. People should be able to drive whatever car they want without fear of going into a store and someone scratching their car or people yelling at them because of the car that … they choose to drive. It’s time for all of us, you know, just to start getting along and knock this stuff off, man. People should be able to be left alone.”

While Chief Hodges did not mention anyone specifically, Minnesota politician and former VP candidate Tim Walz said earlier this month that he “gets a boost” when Tesla stock falls. He later retracted his statement by stating it was just a joke.

Tesla Model Y tops Norway sales despite low Q1 delivery results

The new Model Y ended March as Norway’s top-selling vehicle for the month, with 1,819 units sold.

Tesla did not meet delivery expectations in the first quarter of 2025, and a huge reason behind this was the changeover to the new Model Y in Giga Texas, the Fremont Factory, Giga Shanghai, and Giga Berlin.

Despite Tesla’s disappointing Q1 vehicle delivery results, the new Model Y still made a significant impact in key markets such as Norway.

The new Model Y’s Norway Comeback

While sales of the new Model Y in January and February were low in Norway, the vehicle saw a lot of momentum as soon as deliveries of the updated all-electric crossover started. This resulted in the new Model Y ending March 2025 as Norway’s top-selling vehicle for the month, with 1,819 units sold.

Over the course of Q1 2025, Tesla was able to sell a total of 2,792 Model Y units. That was enough to also make the all-electric crossover Norway’s best-selling vehicle in the first quarter. This is quite an impressive feat for Tesla, especially since sales were throttled during the quarter due to the company’s changeover to the new Model Y.

Tesla in Other European Markets

Tesla’s results in Europe during the first quarter were a mixed bag. In Germany alone, Tesla saw 4,935 vehicles sold in Q1 2025. As per the German road traffic agency KBA, Tesla’s sales in March dropped 42.5% to 2,229 units year-over-year. This was despite overall EV registrations rising 35.3% during the month. 

In Italy, new vehicle registrations rebounded 51% in March from the previous year to 2,217 units, as per data from the Transport Ministry. This is still quite impressive considering that Tesla has become a very polarizing carmaker in Europe, thanks in no small part to CEO Elon Musk’s politics and close relation to U.S. President Donald Trump.
