EXCLUSIVE: Environmental lawyer tasked with suing Tesla speaks: ‘Win Some, Lose Some’
Since Tesla launched the construction of Giga Berlin, the company’s first European vehicle assembly plant in the State of Brandenburg, nearly every element of the project has been met with pushback and backlash from local citizens and other groups. The necessary removal of trees, the displacement of some species on the once forestry-infested property, groundwater, and a coolant tank have all been subjects of complaints brought to the attention of the California-based automaker.
Thousands of miles and a continent away from its home in Northern California, Tesla has sparred with local environmental groups NABU and the Green League for nearly a year, with lawyer Thorsten Deppner representing the Earth-friendly entities. In an exclusive interview with Teslarati, Deppner told us about his intentions for the lawsuit and what is next to come in a long line of issues that the automaker continues to sift through as production of sustainable passenger vehicles nears at the German plant.
Deppner, casually dressed and inviting me into a Zoom-like chatroom to talk about Tesla, was friendly. Knowing my position as a journalist covering the EV space and Tesla, specifically, Deppner was openly willing to talk about the points of the case that were recently put to rest, which has to do with the coolant tank that sits on the property of Giga Berlin. “Tesla had not filed certain documentation with respect to emergency procedures concerning the storage of a particular coolant. That coolant, if ignited, can produce Hydrogen Fluoride,” Deppner told me. “That was our main concern of this particular case.”

The tank was also the subject of a July 2021 investigation by the State Environment Agency, which was originally reported by Tagesspiegel. According to the report, the tank is reportedly holding the chemical tetrafluoropropene, and Tesla does not have permission to have this on the site. The coolant was not, and still is not present in the tank on site. However, Deppner’s cases were already set in motion when the State Agency decided to launch its investigation.
While somewhat risky for the company applying for the permit, this process is also risky for the citizens. Deppner’s most recent issue dealt with coolant tanks on Giga Berlin’s property, following the lawsuit with sand lizards that he won in December, as he proved Tesla broke German Endangered Species Law. A risk for the people in Deppner’s opinion, Tesla did not have the correct documentation to have the coolant tank on site. Safety regulations were not met, which ultimately could have become a risk to the people, especially if the highly toxic contents of the tank were released.
Many of those who have followed Tesla’s process in Berlin as things continue to progress know that preliminary permits were being issued left and right, giving Tesla permission to erect, construct, and perform nearly any task that it needed concrete authorization to perform. Deppner explained that German environmental law allows for those preliminary permits only if an application is more likely to be ultimately approved than not. Then, the company that filed the application will have the opportunity to begin building what was outlined in the documents, provided that the company is guaranteeing to restore the site to its original state if the application should be denied.
This tank was the subject of the most recent NABU and Green League lawsuit, which the groups and Deppner, their representing attorney, dropped. Deppner and the groups lost the injunction on this case, but it is still being monitored.
Deppner told me throughout the conversation on several occasions that the goal was never to have Tesla Giga Berlin shut down; the complaints and lawsuits were more meant to be “guidance.” The goal was to have Tesla adhere to German environmental law throughout the entire process of building Giga Berlin, a misconception that many people do not realize. “We did not want to have this project shut down; we just want Tesla to follow environmental law,” Deppner added.

This is not to say that these groups don’t exist, the ones who would like nothing more than to shut down Tesla’s German operation and halt the spread of sustainable transportation, but Deppner said he was unwilling to represent those groups, as their funding may have been provided by untrustworthy sources. “I wouldn’t represent people or groups like that, not in the slightest,” Deppner said.
The next steps for Deppner are to continue monitoring the Tesla situation until things are ultimately filed, approved, and completed in Brandenburg. As for the attorney, he likely won’t be driving a Tesla anytime soon, but that is not to say that he doesn’t appreciate what the company is doing. He said that the mission of transitioning the world to sustainable energy and transportation is important, and EVs are undoubtedly a step in the right direction. As for the case, Deppner said, “You win some, you lose some.”

Tesla is planning to improve one of the best features on its lineup of cars, a new patent shows. Tesla’s massive glass roof on its premium models is among the coolest additions to the all-electric vehicles, but the design certainly has its complaints, especially from those who live in even slightly warm climates.
Tesla has published a new patent that promises to transform cabin comfort in its electric vehicles, particularly those equipped with the expansive glass roofs.
The document, identified as US20260091643A1 and titled “Airflow Optimization for Cabin Comfort“, addresses that common complaint. Sunlight streaming through windshields and panoramic roofs creates localized hot air pockets near the dashboard and headliner. These pockets generate significant temperature gradients that conventional heating, ventilation, and air conditioning systems struggle to manage evenly.
The exposure to direct sunlight can make the cabin extremely warm, and even after cooling down the interior temperature, combating the continuous stream of sunlight and heat is a challenge. It uses precious energy that is especially pertinent to range and efficiency.
The patent explains how standard dashboard vents push cool air upward, only to entrain warmer air from these stagnant zones and distribute it throughout the occupied cabin space. This process forces the blower to operate at higher speeds, increasing energy consumption and reducing overall efficiency.
In electric vehicles, where every watt impacts driving range, such inefficiencies prove costly.

Research from AAA indicates that air conditioning can diminish range by up to 17 percent under hot conditions. Tesla’s innovation shifts the approach by extracting heat at its source rather than attempting to dilute it after mixing occurs.
Engineers describe a suction HVAC unit connected to dedicated intakes positioned strategically on the upper dashboard surface and within the headliner.
These intakes link to a hot air pocket extraction duct that channels the warmest air directly into the system’s plenum for conditioning. As the blower activates, it simultaneously draws recirculated cabin air and targeted hot pocket air through filters and cooling coils before redistributing conditioned airflow.
It seems somewhat reminiscent of the Tesla heat pump, which aims to combat colder temperatures.

This method reduces entrainment, lowers peak temperatures, and achieves more uniform comfort levels. Testing data reveals that facial temperature gradients drop from 21 degrees Celsius, or 69.8 degrees Fahrenheit, in conventional setups to just 12 degrees Celsius (53.6 degrees F) with the new system. Blower speeds and compressor power requirements decrease appreciably as a result.
The design incorporates smart controls that monitor sunlight intensity and internal temperature distributions in real time. Suction activates selectively only where needed, optimizing energy use without constant high demand. Furthermore, the extraction duct serves a dual purpose.
In the summer months, it pulls hot air inward for cooling; in winter, it reverses to direct warm air outward for rapid windshield defrosting. This versatility allows the reuse of existing hardware with minimal modifications, potentially enabling retrofits in current Tesla fleets.

Tesla saves its passengers again – This time after a 300-foot cliff fall in Malibu
A Tesla Model 3 fell 300 feet off a Malibu cliff and both passengers survived.
A Tesla Model 3 plunged roughly 300 feet off a cliff on Mulholland Highway in Malibu on Friday morning, May 29, 2026, and both occupants survived. The crash was reported at approximately 7:30 a.m. near the 2500 block of Mulholland Highway, triggering a multi-agency rescue operation involving Malibu Search and Rescue, the Los Angeles County Fire Department, the California Highway Patrol, and McCormick Ambulance.
When first responders arrived, the male driver was outside the vehicle shouting for help while the female passenger remained pinned inside the Tesla. Rescue crews rappelled down the cliffside on ropes to reach the wreckage. A flight medic was lowered by helicopter to begin treating both victims, and the driver was hoisted up to the roadway before crews used the Jaws of Life to free the trapped passenger. Both were airlifted to a local trauma center with moderate injuries despite a remarkable result for a fall that steep.
The outcome is not surprising, considering Model 3 earned an overall 5-star rating from NHTSA in every category and sub-category, and recorded the lowest probability of injury of any car ever evaluated by the U.S. New Car Assessment Program. The absence of a traditional engine in the front of the vehicle creates a longer crumple zone that absorbs impact energy before it reaches occupants, and the battery pack running along the floor gives the car an unusually low center of gravity that reinforces structural rigidity.
This is not the first time a Tesla has kept passengers alive after going off a cliff. A Tesla Model Y carrying a family of four survived a plunge off a cliff at Devil’s Slide near San Francisco in January 2023, with two adults and two children walking away from a 250-foot fall. That incident drew widespread attention to how the structural integrity of Tesla’s electric platform performs in extreme crash scenarios that most vehicles would not survive.

Tesla Full Self-Driving (Supervised) has taken yet another significant step forward in Europe. On May 29, Estonia became the third European Union country to approve the advanced driver-assistance technology, following approvals in the Netherlands and Lithuania.
Tesla Europe announced the news on X, confirming the expansion has continued across the continent that, at one time, seemed to be taking its sweet old time giving any approval to the FSD suite.

Estonia’s Transport Administration (Transpordiamet) granted the approval by recognizing the type certification issued by the Dutch vehicle authority RDW. This mutual recognition mechanism, enabled by EU regulations, allows other member states to fast-track deployment without repeating extensive local testing.
The Estonian authority noted that Tesla’s FSD had undergone rigorous evaluation on European roads for approximately 18 months before the initial Dutch approval in April 2026.
FSD Supervised remains classified as a Level 2 advanced driver-assistance system (ADAS). Drivers must maintain full attention, keep their hands on the wheel, and stay ready to intervene at any moment.
The system assists with tasks such as automatic lane changes, navigation through city streets, and responding to traffic objects, but it does not constitute full autonomy. Estonian officials emphasized this distinction, underscoring that safety responsibility lies entirely with the driver.
The rapid progression across the Baltic region highlights Tesla’s strategic approach to European expansion. The Netherlands provided the foundational type approval in April, unlocking doors for neighboring countries.
Lithuania followed swiftly in mid-May, with rollout beginning shortly thereafter. Estonia’s decision, coming just days later, demonstrates how smaller, digitally progressive nations are accelerating adoption.

This expansion builds on Tesla’s global momentum. FSD Supervised is now available in 11 countries worldwide, including the United States, Canada, Australia, and South Korea. In Europe, the approvals signal growing regulatory confidence in Tesla’s vision-based AI approach, which relies on cameras and neural networks rather than lidar or radar-heavy alternatives used by some competitors.
For Tesla, these European milestones are more than symbolic. They validate years of data collection and software iteration while opening new revenue streams through FSD subscriptions and purchases.
As the company continues refining its AI models with real-world miles from diverse driving environments, including Estonia’s variable winter conditions, the dataset grows richer, potentially benefiting global users.
