Level 2 systems like Tesla Autopilot can improve drivers’ attentiveness: IIHS study
The Insurance Institute for Highway Safety (IIHS) recently published the results of a rather unique real-world driver attentiveness test. Using a 2019 Mercedes-Benz C300 equipped with a Level 2 Advanced Driver Assistance System (ADAS) and a giant pink teddy bear dressed in a yellow high-visibility jacket, the agency was able to roughly determine if systems like GM’s Super Cruise and Tesla’s Autopilot make drivers less attentive on the road.
The participants of the study included both drivers who were familiar with Level 2 driver-assist systems and drivers who had little to no experience with ADAS. The IIHS tasked those familiar with Level 2 systems to drive with the Mercedes-Benz C300’s ADAS activated. A group of drivers unfamiliar with ADAS was also tasked to drive with the system engaged. Lastly, a group of drivers who were unfamiliar with the vehicle’s Level 2 system was tasked to drive without the advanced driver-assist feature activated.
To test the drivers’ situational awareness, the IIHS had an SUV with a giant pink teddy bear strapped to its back pass the Mercedes-Benz C300 three times as the participants drove over a stretch of Interstate 70 in Maryland for about an hour. Each time, the SUV with the massive stuffed bear stayed in front of the drivers for about 30 seconds. Researchers then measured the participants’ reactions after their driving session, while asking if they saw anything odd during their hour-long drive.
Interestingly enough, nearly all of the drivers who were experienced with Level 2 systems noticed the giant pink bear. The same group also identified the number of times the bear overtook the C300 during the hour-long test. Drivers who were inexperienced with Level 2 systems didn’t perform as well, with a good number of inexperienced drivers who used the C300’s ADAS failing to remember the giant pink teddy bear at all.
“Our data suggest that Level 2 driving automation has the potential to improve a driver’s situational awareness (SA) once he or she is familiar with the technology, although it does not guarantee it. Unfamiliar drivers, however, appear to have even more difficulty maintaining SA when using the system than when driving without it. On average, participants who were familiar with Level 2 systems showed the highest degree of SA about the bear when using the system, unfamiliar participants who drove with the system off had moderate SA, and unfamiliar participants who drove with the system on demonstrated the lowest SA,” the IIHS wrote.
Videos from inside the C300 showed that the drivers who correctly identified the giant stuffed bear actually spent more time scanning the road ahead of them. These drivers, particularly those familiar with Level 2 systems, even tended to look out of the car’s side windows. On the other hand, those who missed the bear spent a considerable amount of time just focusing on the road straight ahead. Drivers who failed to spot the bear even once spent considerable time looking at various aspects of the C300’s dash.
Considering the results of the IIHS’ study, it appears that some experience with Level 2 systems would be best for drivers before they are allowed access to more advanced driver-assist systems such as Tesla’s Full Self-Driving Beta, which is poised to be rolled out to a greater number of electric car owners in a couple of weeks. Situational awareness, after all, is critical when driving, and having drivers nervously fiddling around their vehicles’ features while operating a Level 2 system may present some risks. That being said, the IIHS’ results do go in line with one of Elon Musk’s more notable points–systems like Autopilot could actually perform as a formidable safety feature, provided that they are used responsibly and properly, of course.

Tesla Semi program Director teases major improvements
Tesla Semi Program Director Dan Priestly teased the major improvements to the all-electric Class 8 truck on Thursday night, following the company’s decision to overhaul the design earlier this year.
Priestley said he drove the Semi on Thursday, and the improvements appear to be welcomed by one of the minds behind the project. “Our customers are going to love it,” he concluded.
Just drove the redesigned Semi. Our customers are going to love it. https://t.co/KZ88sf1CDL

The small detail does not seem like much, but it is coming from someone who has been involved in the development of the truck from A to Z. Priestley has been involved in the Semi program since November 2015 and has slowly worked his way through the ranks, and currently stands as the Director of the program.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
Tesla made some major changes to the Semi design as it announced at the 2025 Annual Shareholder Meeting that it changed the look and design to welcome improvements in efficiency.
Initially, Tesla adopted the blade-like light bar for the Semi, similar to the one that is present on the Model Y Premium and the Cybertruck.
Additionally, there are some slight aesthetic changes to help with efficiency, including a redesigned bumper with improved aero channels, a smaller wraparound windshield, and a smoother roofline for better aero performance.
All of these changes came as the company’s Semi Factory, which is located on Gigafactory Nevada’s property, was finishing up construction in preparation for initial production phases, as Tesla is planning to ramp up manufacturing next year. CEO Elon Musk has said the Semi has attracted “ridiculous demand.”
The Semi has already gathered many large companies that have signed up to buy units, including Frito-Lay and PepsiCo., which have been helping Tesla test the vehicle in a pilot program to test range, efficiency, and other important metrics that will be a major selling point.
Tesla will be the Semi’s first user, though, and the truck will help solve some of the company’s logistics needs in the coming years.

Tesla dominates in the UK with Model Y and Model 3 leading the way
Tesla is dominating in the United Kingdom so far through 2025, and with about two weeks left in the year, the Model Y and Model 3 are leading the way.
The Model Y and Model 3 are the two best-selling electric vehicles in the United Kingdom, which is comprised of England, Scotland, Wales, and Northern Ireland, and it’s not particularly close.
According to data gathered by EU-EVs, the Model Y is sitting at 18,890 units for the year, while the Model 3 is slightly behind with 16,361 sales for the year so far.
The next best-selling EV is the Audi Q4 e-tron at 10,287 units, lagging significantly behind but ahead of other models like the BMW i4 and the Audi Q6 e-tron.
GOOD NEWS 🇬🇧 Tesla is absolutely crushing the UK electric vehicle market in 2025 💥
The numbers are in, and the dominance is clear. With an impressive amount of 42,270 vehicles delivered year-to-date, the brand now commands a solid 9.6% market share of the total auto market 🆒… pic.twitter.com/dkiGX9kzd0

The Model Y has tasted significant success in the global market, but it has dominated in large markets like Europe and the United States.
For years, it’s been a car that has fit the bill of exactly what consumers need: a perfect combination of luxury, space, and sustainability.
Both vehicles are going to see decreases in sales compared to 2024; the Model Y was the best-selling car last year, but it sold 32,610 units in the UK. Meanwhile, the Model 3 had reached 17,272 units, which will keep it right on par with last year.
Tesla sold 50,090 units in the market last year, and it’s about 8,000 units shy of last year’s pace. It also had a stronger market share last year with 13.2 percent of the sales in the market. With two weeks left in 2025, Tesla has a 9.6 percent market share, leading Volkswagen with 8 percent.
The company likely felt some impact from CEO Elon Musk’s involvement with the Trump administration and, more specifically, his role with DOGE. However, it is worth mentioning that some months saw stronger consumer demand than others. For example, sales were up over 20 percent in February. A 14 percent increase followed this in June.

Tesla Insurance officially expands to new U.S. state
Tesla’s in-house Insurance program first launched back in late 2019, offering a new way to insure the vehicles that was potentially less expensive and could alleviate a lot of the issues people had with claims, as the company could assess and repair the damage itself.
Tesla Insurance has officially expanded to a new U.S. state, its thirteenth since its launch in 2019.
Tesla has confirmed that its in-house Insurance program has officially made its way to Florida, just two months after the company filed to update its Private Passenger Auto program in the state. It had tried to offer its insurance program to drivers in the state back in 2022, but its launch did not happen.
Instead, Tesla refiled the paperwork back in mid-October, which essentially was the move toward initiating the offering this month.
BREAKING: Tesla Insurance has just officially launched in Florida.
This is the first new state to receive @Tesla Insurance in more than 3 years. In total, Tesla insurance is now available in 13 U.S. states (map in thread below of all the states).

Tesla’s in-house Insurance program first launched back in late 2019, offering a new way to insure the vehicles that was potentially less expensive and could alleviate a lot of the issues people had with claims, as the company could assess and repair the damage itself.
It has expanded to new states since 2019, but Florida presents a particularly interesting challenge for Tesla, as the company’s entry into the state is particularly noteworthy given its unique insurance landscape, characterized by high premiums due to frequent natural disasters, dense traffic, and a no-fault system.
Annual average premiums for Florida drivers hover around $4,000 per year, well above the national average. Tesla’s insurance program could disrupt this, especially for EV enthusiasts. The state’s growing EV adoption, fueled by incentives and infrastructure development, aligns perfectly with Tesla’s ecosystem.
Moreover, there are more ways to have cars repaired, and features like comprehensive coverage for battery damage and roadside assistance tailored to EVs address those common painpoints that owners have.
However, there are some challenges that still remain. Florida’s susceptibility to hurricanes raises questions about how Tesla will handle claims during disasters.
Looking ahead, Tesla’s expansion of its insurance program signals the company’s ambition to continue vertically integrating its services, including coverage of its vehicles. Reducing dependency on third-party insurers only makes things simpler for the company’s automotive division, as well as for its customers.
