New data from Recurrent Auto show that used EV batteries are lasting far longer than critics claim.

Talk to anyone even remotely on the fence about buying an electric vehicle, and you will surely hear one worry above all others; “What happens when the battery dies? Those things are expensive,” they will exclaim. This is often accompanied by a sarcastic smirk and a comment like, “it’ll be dead and gone by 60,000 miles!” Luckily, new data from Recurrent Auto shows precisely what these claims are, myths.

Recurrent surveyed just over 15,000 EV owners and compiled some of the most detailed battery health data ever assembled, showing that EV batteries are lasting far longer than critics and owners have anticipated. Of their massive group of owners, only 1.5% had replaced their batteries outside of a recall or warranty period. Most of those were older Nissan Leafs lacking liquid battery temperature control systems.

Recurrent’s survey included data from 13 vehicle models, including the Tesla Model S, Model 3, and Model Y; Chevy Bolt, Bolt EUV, and Volt; Hyundai Kona; BMW i3; Audi e-tron; Nissan Leaf; Hyundai Kona and IONIQ 5; and Ford Mustang Mach-E.

Beyond the minimal number of owners who had been forced to replace their batteries, Recurrent found that battery degradation was not a linear phenomenon. From each of the surveyed groups, while the EV range peaked within 10-20,000 miles, it quickly degraded and flatlined as it approached 100,000 miles.

“It is encouraging to see this latest study as another challenge to the idea that electric cars are a ticking time bomb of maintenance costs,” said Scott Case, CEO at Recurrent. “Vehicle ownership is full of surprises. While no one can change that, I hope that we begin to make sure that batteries are not one of those surprises.”

Due to the relative novelty of electric vehicles on the market, significant amounts of data are not currently available on the effect of mileage above 100,000 miles. However, from many anecdotal stories, there does seem to be a trend of many vehicles retaining their range past the 100,000-mile mark.

Recurrent attributes this phenomenon to two main technologies; battery management systems and battery temperature control systems, both of which have dramatically improved the longevity of batteries. These systems not only allow owners to limit how much their battery is charged, which can substantially damage a battery’s health, but they also ensure they are constantly operating at a safe and “healthy” temperature.

Perhaps the best takeaway from Recurrent’s data regards the used EV market, which many sadly believe to be a minefield of risky cars with batteries on the verge of combustion. Thanks to the data collection Recurrent provides users and auto dealers alike, more and more people can feel confident about the battery health of the used EV they hope to buy.

Tesla Full Self-Driving (FSD) testing gains major ground in Spain

Based on information posted by the Dirección General de Tráfico (DGT), it appears that Tesla is already busy testing FSD in the country.

Tesla’s Full Self-Driving (Supervised) program is accelerating across Europe, with Spain emerging as a key testing hub under the country’s new ES-AV framework program.

Based on information posted by the Dirección General de Tráfico (DGT), it appears that Tesla is already busy testing FSD in the country.

Spain’s ES-AV framework

Spain’s DGT launched the ES-AV Program in July 2025 to standardize testing for automated vehicles from prototypes to pre-homologation stages. The DGT described the purpose of the program on its official website.

“The program is designed to complement and enhance oversight, regulation, research, and transparency efforts, as well as to support innovation and advancements in automotive technology and industry. This framework also aims to capitalize on the opportunity to position Spain as a pioneer and leader in automated vehicle technology, seeking to provide solutions that help overcome or alleviate certain shortcomings or negative externalities of the current transportation system,” the DGT wrote. 

The program identifies three testing phases based on technological maturity and the scope of a company’s operations. Each phase has a set of minimum eligibility requirements, and applicants must indicate which phase they wish to participate in, at least based on their specific technological development.

Tesla FSD tests

As noted by Tesla watcher Kees Roelandschap on X, the DGT’s new framework effectively gives the green flight for nationwide FSD testing. So far, Tesla Spain has a total of 19 vehicles authorized to test FSD on the country’s roads, though it would not be surprising if this fleet grows in the coming months.

The start date for the program is listed at November 27, 2025 to November 26, 2027. The DGT also noted that unlimited FSD tests could be done across Spain on any national route. And since Tesla is already in Phase 3 of the ES-AV Program, onboard safety operators are optional. Remote monitoring would also be allowed. 

Tesla’s FSD tests in Spain could help the company gain a lot of real-world data on the country’s roads. Considering the scope of tests that are allowed for the electric vehicle maker, it seems like Spain would be one of the European countries that would be friendly to FSD’s operations. So far, Tesla’s FSD push in Europe is notable, with the company holding FSD demonstrations in Germany, France, and Italy. Tesla is also pushing for national approval in the Netherlands in early 2026.

Tesla’s Full Self-Driving (Supervised) software continues its rapid evolution, with the latest V14.2.1 update drawing widespread praise for its smoother performance and smarter decision-making.

Videos and firsthand accounts from Tesla owners highlight V14.2.1 as an update that improves navigation responsiveness, sign recognition, and overall fluidity, among other things. Some drivers have even described it as “more alive than ever,” hinting at the system eventually feeling “sentient,” as Elon Musk has predicted.

FSD V14.2.1 first impressions

Early adopters are buzzing about how V14.2.1 feels less intrusive while staying vigilant. In a post shared on X, Tesla owner @LactoseLunatic described the update as a “huge leap forward,” adding that the system remains “incredibly assertive but still safe.”

Another Tesla driver, Devin Olsenn, who logged ~600 km on V14.2.1, reported no safety disengagements, with the car feeling “more alive than ever.” The Tesla owner noted that his wife now defaults to using FSD V14, as the system is already very smooth and refined.

Adverse weather and regulatory zones are testing grounds where V14.2.1 shines, at least according to testers in snow areas. Tesla watcher Sawyer Merritt shared a video of his first snowy drive on unplowed rural roads in New Hampshire, where FSD did great and erred on the side of caution. As per Merritt, FSD V14.2.1 was “extra cautious” but it performed well overall.

Sign recognition and freeway prowess

Sign recognition also seemed to show improvements with FSD V14.2.1. Longtime FSD tester Chuck Cook highlighted a clip from his upcoming first-impressions video, showcasing improved school zone behavior. “I think it read the signs better,” he observed, though in standard mode, it didn’t fully drop to 15 mph within the short timeframe. This nuance points to V14.2.1’s growing awareness of temporal rules, a step toward fewer false positives in dynamic environments.

FSD V14.2.1 also seems to excel in high-stress highway scenarios. Fellow FSD tester @BLKMDL3 posted a video of FSD V14.2.1 managing a multi-lane freeway closure due to a police chase-related accident. “Perfectly handles all lanes of the freeway merging into one,” the Tesla owner noted in his post on X.

FSD V14.2.1 was released on Thanksgiving, much to the pleasant surprise of Tesla owners. The update’s release notes are almost identical to the system’s previous iteration, save for one line item read, “Camera visibility can lead to increased attention monitoring sensitivity.”

Tesla has kicked off passenger ride-alongs for Full Self-Driving (Supervised) in Italy, France and Germany. The program allows the public to hop in as a non-driving observer to witness FSD navigate urban streets firsthand. 

The program, detailed on Tesla’s event pages, arrives ahead of a potential early 2026 Dutch regulatory approval that could unlock a potential EU-wide rollout for FSD.

Hands-Off Demos

Tesla’s ride-along invites participants to “ride along in the passenger seat to experience how it handles real-world traffic & the most stressful parts of daily driving, making the roads safer for all,” as per the company’s announcement on X through its official Tesla Europe & Middle East account. 

Sign-ups via localized pages offer free slots through December, with Tesla teams piloting vehicles through city streets, roundabouts and highways.

“Be one of the first to experience Full Self-Driving (Supervised) from the passenger seat. Our team will take you along as a passenger and show you how Full Self-Driving (Supervised) works under real-world road conditions,” Tesla wrote. “Discover how it reacts to live traffic and masters the most stressful parts of driving to make the roads safer for you and others. Come join us to learn how we are moving closer to a fully autonomous future.”

Building trust towards an FSD Unsupervised rollout

Tesla’s FSD (Supervised) ride-alongs could be an effective tool to build trust and get regular car buyers and commuters used to the idea of vehicles driving themselves. By seating riders shotgun, Tesla could provide participants with a front row seat to the bleeding edge of consumer-grade driverless systems.

FSD (Supervised) has already been rolled out to several countries, such as the United States, Canada, Australia, New Zealand, and partially in China. So far, FSD (Supervised) has been received positively by drivers, as it really makes driving tasks and long trips significantly easier and more pleasant.

FSD is a key safety feature as well, which became all too evident when a Tesla driving on FSD was hit by what seemed to be a meteorite in Australia. The vehicle moved safely despite the impact, though the same would likely not be true had the car been driven manually.
