Tesla’s crazy laser windshield wipers have been published by the US Patent Office
Tesla’s idea for a crazy windshield wiper that would clear debris from a driver’s line of sight using a laser beam has been officially published by the United States Patent Office. Tesla filed the application for the patent in May 2019, and it finally was granted in late 2021. Now, the U.S. Patent Office has published the patent, making it publicly viewable.
Tesla has long been interested in some pretty crazy and revolutionary ideas for automobiles. Over the years, Tesla has looked at several different designs and ideas for windshield wipers, using anything from a single-wiper system for the Next-Gen Roadster that would utilize an electromagnetic linear actuator to rid the windshield of moisture, to no wipers at all when it unveiled the Cybertruck in November 2019. Most recent sightings of Tesla’s Cybertruck have indicated the vehicle will have wipers, but Tesla is still revising the design.
With all of the crazy ideas Tesla has thrown around for wipers in the past, the patent for the automaker’s “Pulsed Laser Cleaning of Debris Accumulated on Glass Articles in Vehicles and Photovoltaic Assemblies” is among the most interesting. Originally filed in May 2019, Tesla recently had the idea published by the U.S. Patent Office, meaning if the Office does not ultimately grant the patent, the public can still learn from the work and perhaps develop another system that could be granted.
Tesla describes the patent in the now-published filing:
A cleaning system for a vehicle includes a beam optics assembly that emits a laser beam to irradiate a region on a glass article of the vehicle, debris detection circuitry that detects debris accumulated over the region, and control circuitry. The control circuitry calibrates a set of parameters associated with the laser beam emitted from the beam optics assembly based on detection of the debris accumulated over the region on the glass article, controls an exposure level of the laser beam on the debris accumulated based on calibration of the set of parameters associated with the laser beam, wherein the exposure level is controlled based on pulsing the laser beam at a calibrated rate that limits penetration of the laser beam to a depth that is less than a thickness of the glass article and removes the debris accumulated over the region on the glass article using the laser beam.”
It is not necessarily confirmed or known what plans Tesla may have for the laser windshield wipers, but illustrations within the patent do seem to display a Model S body. Tesla may be willing to test this type of apparatus on some of its vehicles in-house, but the automaker has never detailed specific plans for the idea.

Tesla’s flowchart describing the process for the patent is relatively simple, and also shows uses with clearing debris from solar panels. In five steps, the patent describes the use of the laser cleaning assembly:
- Detect debris accumulated on a region on glass article installed in vehicle
- Calibrate a set of parameters associated with laser beam emitted from beam optics assembly, based on detection of debris accumulated on a region on glass article
- Control exposure level of laser beam on detected debris accumulated on glass article based on calibration of set of parameters associated with laser beam
- Irradiate region associated with the detected debris on glass article by laser beam
- Remove detected debris accumulated on region by laser beam
It doesn’t appear to be operated by the vehicle itself, either. Tesla describes the potential for a manual system where the driver could control the laser with a touchscreen, joystick, or another medium to communicate with different operational components of the cleaning apparatus.
While it seems like an outlandish and potentially satirical idea, it would not be too far past Tesla’s realm of ideas to use a laser to clear a windshield. After all, CEO Elon Musk has said in the past that the Roadster will fly thanks to SpaceX cold gas thrusters, Tesla has filed a patent for the Cybertruck to have solar cells on its tonneau for additional electric vehicle range, and plenty of other insane ideas. However, the new laser patent, if ultimately used by Tesla, would only decrease the already-minimal maintenance costs owners deal with, as yearly keep-up costs on EVs are extremely low.

Tesla stock (NASDAQ: TSLA) closed at an all-time high on Tuesday, jumping over 3 percent during the day and finishing at $489.88.
The price beats the previous record close, which was $479.86.
Shares have had a crazy year, dipping more than 40 percent from the start of the year. The stock then started to recover once again around late April, when its price started to climb back up from the low $200 level.
This week, Tesla started to climb toward its highest levels ever, as it was revealed on Sunday that the company was testing driverless Robotaxis in Austin. The spike in value pushed the company’s valuation to $1.63 trillion.

It is the seventh-most valuable company on the market currently, trailing Nvidia, Apple, Alphabet (Google), Microsoft, Amazon, and Meta.
Shares closed up $14.57 today, up over 3 percent.
The stock has gone through a lot this year, as previously mentioned. Shares tumbled in Q1 due to CEO Elon Musk’s involvement with the Department of Government Efficiency (DOGE), which pulled his attention away from his companies and left a major overhang on their valuations.
However, things started to rebound halfway through the year, and as the government started to phase out the $7,500 tax credit, demand spiked as consumers tried to take advantage of it.
Q3 deliveries were the highest in company history, and Tesla responded to the loss of the tax credit with the launch of the Model 3 and Model Y Standard.
Additionally, analysts have announced high expectations this week for the company on Wall Street as Robotaxi continues to be the focus. With autonomy within Tesla’s sights, things are moving in the direction of Robotaxi being a major catalyst for growth on the Street in the coming year.

Tesla needs to come through on this one Robotaxi metric, analyst says
“We think the key focus from here will be how fast Tesla can scale driverless operations (including if Tesla’s approach to software/hardware allows it to scale significantly faster than competitors, as the company has argued), and on profitability.”
Tesla needs to come through on this one Robotaxi metric, Mark Delaney of Goldman Sachs says.
Tesla is in the process of rolling out its Robotaxi platform to areas outside of Austin and the California Bay Area. It has plans to launch in five additional cities, including Houston, Dallas, Miami, Las Vegas, and Phoenix.
However, the company’s expansion is not what the focus needs to be, according to Delaney. It’s the speed of deployment.

Profitability will come as the Robotaxi fleet expands. Making that money will be dependent on when Tesla can initiate rides in more areas, giving more customers access to the program.
There are some additional things that the company needs to make happen ahead of the major Robotaxi expansion, one of those things is launching driverless rides in Austin, the first city in which it launched the program.
This week, Tesla started testing driverless Robotaxi rides in Austin, as two different Model Y units were spotted with no occupants, a huge step in the company’s plans for the ride-sharing platform.
Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
CEO Elon Musk has been hoping to remove Safety Monitors from Robotaxis in Austin for several months, first mentioning the plan to have them out by the end of 2025 in September. He confirmed on Sunday that Tesla had officially removed vehicle occupants and started testing truly unsupervised rides.
Although Safety Monitors in Austin have been sitting in the passenger’s seat, they have still had the ability to override things in case of an emergency. After all, the ultimate goal was safety and avoiding any accidents or injuries.
Goldman Sachs reiterated its ‘Neutral’ rating and its $400 price target. Delaney said, “Tesla is making progress with its autonomous technology,” and recent developments make it evident that this is true.

Tesla gets bold Robotaxi prediction from Wall Street firm
Last week, Andrew Percoco took over Tesla analysis for Morgan Stanley from Adam Jonas, who covered the stock for years. Percoco seems to be less optimistic and bullish on Tesla shares, while still being fair and balanced in his analysis.
Tesla (NASDAQ: TSLA) received a bold Robotaxi prediction from Morgan Stanley, which anticipates a dramatic increase in the size of the company’s autonomous ride-hailing suite in the coming years.
Last week, Andrew Percoco took over Tesla analysis for Morgan Stanley from Adam Jonas, who covered the stock for years. Percoco seems to be less optimistic and bullish on Tesla shares, while still being fair and balanced in his analysis.
Percoco dug into the Robotaxi fleet and its expansion in the coming years in his latest note, released on Tuesday. The firm expects Tesla to increase the Robotaxi fleet size to 1,000 vehicles in 2026. However, that’s small-scale compared to what they expect from Tesla in a decade.
Tesla expands Robotaxi app access once again, this time on a global scale
By 2035, Morgan Stanley believes there will be one million Robotaxis on the road across multiple cities, a major jump and a considerable fleet size. We assume this means the fleet of vehicles Tesla will operate internally, and not including passenger-owned vehicles that could be added through software updates.
He also listed three specific catalysts that investors should pay attention to, as these will represent the company being on track to achieve its Robotaxi dreams:
- Opening Robotaxi to the public without a Safety Monitor. Timing is unclear, but it appears that Tesla is getting closer by the day.
- Improvement in safety metrics without the Safety Monitor. Tesla’s ability to improve its safety metrics as it scales miles driven without the Safety Monitor is imperative as it looks to scale in new states and cities in 2026.
- Cybercab start of production, targeted for April 2026. Tesla’s Cybercab is a purpose-built vehicle (no steering wheel or pedals, only two seats) that is expected to be produced through its state-of-the-art unboxed manufacturing process, offering further cost reductions and thus accelerating adoption over time.
Robotaxi stands to be one of Tesla’s most significant revenue contributors, especially as the company plans to continue expanding its ride-hailing service across the world in the coming years.
Its current deployment strategy is controlled and conservative to avoid any drastic and potentially program-ruining incidents.
So far, the program, which is active in Austin and the California Bay Area, has been widely successful.
