Tesla’s patent for a stealthy, electromagnetic wiper is perfect for the new Roadster
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 dispels reports of ‘sales suspension’ in California
“This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.
Sales in California will continue uninterrupted.”
Tesla has dispelled reports that it is facing a thirty-day sales suspension in California after the state’s Department of Motor Vehicles (DMV) issued a penalty to the company after a judge ruled it “misled consumers about its driver-assistance technology.”
On Tuesday, Bloomberg reported that the California DMV was planning to adopt the penalty but decided to put it on ice for ninety days, giving Tesla an opportunity to “come into compliance.”
Tesla enters interesting situation with Full Self-Driving in California
Tesla responded to the report on Tuesday evening, after it came out, stating that this was a “consumer protection” order that was brought up over its use of the term “Autopilot.”
The company said “not one single customer came forward to say there’s a problem,” yet a judge and the DMV determined it was, so they want to apply the penalty if Tesla doesn’t oblige.
However, Tesla said that its sales operations in California “will continue uninterrupted.”
It confirmed this in an X post on Tuesday night:

The report and the decision by the DMV and Judge involved sparked outrage from the Tesla community, who stated that it should do its best to get out of California.
One X post said California “didn’t deserve” what Tesla had done for it in terms of employment, engineering, and innovation.
Tesla has used Autopilot and Full Self-Driving for years, but it did add the term “(Supervised)” to the end of the FSD suite earlier this year, potentially aiming to protect itself from instances like this one.
This is the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” naming. Previous Transportation Secretary Pete Buttigieg was vocally critical of the use of the name “Full Self-Driving,” as well as “Autopilot.”

New EV tax credit rule could impact many EV buyers
We confirmed with a Tesla Sales Advisor that any current orders that have the $7,500 tax credit applied to them must be completed by December 31, meaning delivery must take place by that date. However, it is unclear at this point whether someone could still claim the credit when filing their tax returns for 2025 as long as the order reflects an order date before September 30.
Tesla owners could be impacted by a new EV tax credit rule, which seems to be a new hoop to jump through for those who benefited from the “extension,” which allowed orderers to take delivery after the loss of the $7,500 discount.
After the Trump Administration initiated the phase-out of the $7,500 EV tax credit, many were happy to see the rules had been changed slightly, as deliveries could occur after the September 30 cutoff as long as orders were placed before the end of that month.
However, there appears to be a new threshold that EV buyers will have to go through, and it will impact their ability to get the credit, at least at the Point of Sale, for now.
Delivery must be completed by the end of the year, and buyers must take possession of the car by December 31, 2025, or they will lose the tax credit. The U.S. government will be closing the tax credit portal, which allows people to claim the credit at the Point of Sale.
🚨UPDATE: $7,500 Tax Credit Portal “Closes By End of Year”.
This is bad news for pending Tesla buyers (MYP) looking to lock in the $7,500 Tax Credit.

However, it is unclear at this point whether someone could still claim the credit when filing their tax returns for 2025 as long as the order reflects an order date before September 30.
If not, the order can still go through, but the buyer will not be able to claim the tax credit, meaning they will pay full price for the vehicle.
This puts some buyers in a strange limbo, especially if they placed an order for the Model Y Performance. Some deliveries have already taken place, and some are scheduled before the end of the month, but many others are not expecting deliveries until January.

Elon Musk takes latest barb at Bill Gates over Tesla short position
Bill Gates placed a massive short bet against Tesla of ~1% of our total shares, which might have cost him over $10B by now
Elon Musk took his latest barb at former Microsoft CEO Bill Gates over his short position against the company, which the two have had some tensions over for a number of years.
Gates admitted to Musk several years ago through a text message that he still held a short position against his sustainable car and energy company. Ironically, Gates had contacted Musk to explore philanthropic opportunities.

Musk said he could not take the request seriously, especially as Gates was hoping to make money on the downfall of the one company taking EVs seriously.
The Tesla frontman has continued to take shots at Gates over the years from time to time, but the latest comment came as Musk’s net worth swelled to over $600 billion. He became the first person ever to reach that threshold earlier this week, when Tesla shares increased due to Robotaxi testing without any occupants.
Musk refreshed everyone’s memory with the recent post, stating that if Gates still has his short position against Tesla, he would have lost over $10 billion by now:

Just a month ago, in mid-November, Musk issued his final warning to Gates over the short position, speculating whether the former Microsoft frontman had still held the bet against Tesla.
“If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon,” Musk said. This came in response to The Gates Foundation dumping 65 percent of its Microsoft position.

Musk’s involvement in the U.S. government also drew criticism from Gates, as he said that the reductions proposed by DOGE against U.S.A.I.D. were “stunning” and could cause “millions of additional deaths of kids.”
“Gates is a huge liar,” Musk responded.
It is not known whether Gates still holds his Tesla short position.
