A recently published patent application from Tesla has revealed that the electric car maker is designing a stealthy, unconventional windshield wiper system that seems particularly tailor-fit for the company’s upcoming halo car: the next-generation Roadster. Apart from looking the part of a futuristic wiper assembly for a futuristic vehicle, Tesla’s patent also allows optimizations in range. 

As background, Tesla noted that conventional wiper systems usually utilize electric motors that move one or more wiper blades to clean the windshield of a vehicle. The assembly of such systems involves several mechanical components such as gears and bearings, which, in turn, enable the wiper blades to slide across the windshield. 

This sliding motion of the mechanical components creates significant friction during operation. This results in the need for additional power to be supplied by a car’s in-vehicle battery, thereby reducing an electric vehicle’s range. Traditional wiper systems are usually prone to rust and wear as well, which could bog down a wiper assembly and make it inefficient in cleaning a windshield. This could be an issue in regions that experience a lot of rain or snow.

With this in mind, Tesla argues that there is a need to design an innovative windshield wiper system that cleans better, and lasts longer. Such a system was outlined in a recently published patent, plainly titled “Electromagnetic Windshield Wiper System.” Tesla’s design for its electromagnetic windshield wiper system involves the use of a “linear actuator that may include a guide rail and an electromagnetic moving block.” The design is modular, enabling easy installation. The wiper arm and blade could be attached to each other as well, forming a “linear mono wiper in an uncluttered design.” Tesla describes how its windshield wiper assembly works as follows. 

“The disclosed electromagnetic wiper system may include a linear actuator that may include a guide rail and an electromagnetic moving block. The guide rail may include a plurality of permanent magnet bars that may be disposed horizontally along a curvature of the windshield of the vehicle. The electromagnetic moving block may act as an electromagnetic train, and may include a plurality of perforations and at least an electromagnetic coil that surrounds the plurality of perforations in the electromagnetic moving block. 

“The linear motion of the electromagnetic moving block through the plurality of permanent magnet bars may be controlled to steer the wiper arm that may be coupled to the electromagnetic moving block, back and forth across the entire length of the windshield to wipe a defined region, for example, the entire transparent area (i.e., near cent percent area) of the windshield. This may result in minimal friction during the linear motion of the electromagnetic moving block.”

What is pretty interesting about Tesla’s electromagnetic windshield wiper patent is that the entire mono wiper assembly stows away beneath the hood of a vehicle when not in use. This, apart from giving an electric car windshield a clean, uncluttered look, improves a car’s aerodynamic performance during operations. Tesla notes that these optimizations will be particularly significant at high speeds. 

Tesla did not state which of its present or upcoming vehicles will be using the electromagnetic windshield wiper system outlined in the recently published patent. That being said, a look at the benefits of Tesla’s design suggests that the innovative wiper system will be a perfect fit for the next-generation Roadster.

The Roadster’s static models sported a conventional wiper system, after all, and they look almost out of place in such a futuristic vehicle. Considering that the new Roadster is Tesla’s halo car, it makes perfect sense for the company to go all out in its optimizations, windshield wipers included. Couple that with the Roadster’s emphasis on aerodynamics and high-speed driving and this patent makes even more sense for the all-electric supercar.

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.

Swedish union rep pissed that Tesla is working around a postal blockade they started

Tesla Sweden is now using dozens of private residences as a way to obtain license plates for its vehicles.

Two years into their postal blockade, Swedish unions are outraged that Tesla is still able to provide its customers’ vehicles with valid plates through various clever workarounds. 

Seko chairman Gabriella Lavecchia called it “embarrassing” that the world’s largest EV maker, owned by CEO Elon Musk, refuses to simply roll over and accept the unions’ demands.

Unions shocked Tesla won’t just roll over and surrender

The postal unions’ blockade began in November 2023 when Seko and IF Metall-linked unions stopped all mail to Tesla sites to force a collective agreement. License plates for Tesla vehicles instantly became the perfect pressure point, as noted in a Dagens Arbete report.

Tesla responded by implementing initiatives to work around the blockades. A recent investigation from Arbetet revealed that Tesla Sweden is now using dozens of private residences, including one employee’s parents’ house in Trångsund and a customer-relations staffer’s home in Vårby, as a way to obtain license plates for its vehicles.

Seko chairman Gabriella Lavecchia is not pleased that Tesla Sweden is working around the unions’ efforts yet again. “It is embarrassing that one of the world’s largest car companies, owned by one of the world’s richest people, has sunk this low,” she told the outlet. “Unfortunately, it is completely frivolous that such a large company conducts business in this way.”

Two years on and plates are still being received

The Swedish Transport Agency has confirmed Tesla is still using several different workarounds to overcome the unions’ blockades.

As noted by DA, Tesla Sweden previously used different addresses to receive its license plates. At one point, the electric vehicle maker used addresses for car care shops. Tesla Sweden reportedly used this strategy in Östermalm in Stockholm, as well as in Norrköping and Gothenburg.

Another strategy that Tesla Sweden reportedly implemented involved replacement plates being ordered by private individuals when vehicles change hands from Tesla to car buyers. There have also been cases where the police have reportedly issued temporary plates to Tesla vehicles.
