The user experience of Tesla’s electric cars is centered mostly on the vehicles’ large, high-resolution displays. Coupled with custom software that provides a quick, smartphone-like experience, Tesla’s screens in its vehicles are already among the best in the auto industry. But in the spirit of the company’s habit of constant innovation, it appears that Tesla is looking to improve the quality of its displays even more. 

A recently published patent from the electric car maker, titled “Holographic Decorated Glass for Screen Color Matching,” outlines a way for the electric car maker to improve the viewing angles of its vehicles’ displays. In the patent, Tesla notes that “because display screens typically have a periodic micro-structure (e.g., a pixelated structure), the color of the display screen may be dependent on the angle at which a viewer is looking at the display screen.” This results in viewing angles that have significant room for improvement, even among high-quality screens. 

“The non-displaying portions of the device may be unable to match this angular color dependence of the display screen, resulting in a readily visible boundary between the display screen and the non-displaying portions of the device. Accordingly, there is a need for better color integration between the displaying portions of a device and the non-displaying portions of the device,” Tesla wrote.

To address this, Tesla opted to utilize a pigmented frame and index match glue to coat its vehicles’ screens, as well as a holographic glass panel. By adopting these techniques, Tesla expects to provide its vehicles with a screen that can offer optimal viewing angles for all passengers. This is especially useful when paired with the company’s entertainment features such as Tesla Theater or Tesla Arcade, which are accessible when a vehicle is on Park. 

Tesla describes its use of index match glue and holographic glass panels as follows. 

“Index match glue 206 may change the perceived color and appearance of display 204 to match the color and appearance of surrounding frame 202 within a small range of viewing angles. For example, index match glue 206 may change the perceived color and appearance of display 204 to match the color and appearance of frame 202 within a range of viewing angles approximately normal to the surface of display 204. However, due to the angular dependence of the perceived color and appearance of display 204 (due to display 204 having a holographic structure resulting from the pixels of display 204), index match glue 206 may be unable to change the perceived color and appearance of display 204 to match the color and appearance of frame 202 within a broad range of viewing angles so that the boundary between frame 202 and display 204 is invisible to a viewer. Accordingly, with display 204 coated with index match glue 206 surrounded by frame 202, the boundary between frame 202 and display 204 may still be readily visible at certain viewing angles.”

“The directionality of the periodic structure of holographic film 402 may approximate or match the directionality of the periodic structure of display 406. For example, if display 406 includes a plurality of periodic features (e.g., pixels) oriented in a first direction (e.g., rectangles, triangles, or the like having a common orientation), holographic film 402 may include a plurality of periodic features oriented in the first direction. FIG. 5 shows exemplary system 500 in which the visibility of a boundary between display 504 and a surrounding frame including a holographic structure (here holographic glass panel 502) may be reduced or eliminated over a broad range of viewing angles. In exemplary system 500, a periodic structure is formed on holographic glass panel 502 directly. For example, laser etching on holographic glass panel 502 may produce the periodic structure responsible for the holographic effect of holographic glass panel 502. Holographic glass panel 502 may include holographic structures formed in a variety of other ways, including ablation, etching, deposition processes, and the like.”

A color-matched display with optimal viewing angles might be a rather minor aspect of a vehicle, but for connected cars such as Teslas, it is these little things that make a difference in user experience. A car that boasts some of the most advanced automotive tech available in the auto segment today, after all, deserves a screen that is on par with some of the best mobile devices on the market. 

Tesla’s display design outlined in its recently published patent can come in handy as well, particularly as the electric car maker introduces more updates to its fleet of vehicles. Among these is a “Fade Mode,” which Elon Musk has hinted at in the past. While responding to a Twitter follower last year, Musk responded positively to the suggestion of adding an option that allows drivers to dim their vehicles’ display while a car is in motion. This, together with features like V10’s Joe Mode, could help make long trips in Tesla’s electric vehicles much more convenient for passengers.

Elon Musk rips ABC News over fatal NYC Tesla crash report

Musk pushed back on NYC Tesla crash coverage, pointing to a pattern of premature blame.

Published

By

Elon Musk pushed back overnight against media framing of a fatal Tesla crash in Midtown Manhattan, telling a user on X that “it wasn’t the car” and that the vehicle’s Autopilot system had nothing to do with the wreck.

The crash happened just before 3 a.m. Wednesday, when a 2024 Tesla Model Y struck a sidewalk shed outside 315 Madison Ave., a bus stop pole and a mailbox on East 42nd Street, according to the NYPD. The car kept moving several more blocks before stopping near Second Avenue. Both women inside, each 27, were taken to Bellevue Hospital, where the passenger was pronounced dead. The driver was charged with vehicular manslaughter, driving while ability impaired and leaving the scene of an accident.

Police have not attributed the crash to Autopilot or Full Self-Driving in any public statement. The charges point to impairment, not software. Musk’s response followed a since-deleted ABC News post that he said mischaracterized the incident. Replying to a user on X, Musk wrote that if Autopilot had been engaged, “they would not have crashed,” and added that “the legacy media will never forgive Tesla for failing to advertise with them,”

It’s a familiar cycle for Tesla. In June, headlines from several national outlets described a fatal crash in Katy, Texas, as happening while the car was “on autopilot,” based on the driver’s own account to police after his Model 3 struck a home and killed a 76-year-old woman. Tesla’s data told a different story when Ashok Elluswamy, Tesla’s head of AI, said the driver had pressed the accelerator to 100% and reached 73 mph in a residential zone. Harris County prosecutors later confirmed the human override and the driver was charged with manslaughter.

Florida Gov. Ron DeSantis pointed to that same Katy crash last month to argue that outlets routinely name Tesla in crash headlines while leaving other automakers unnamed, even after a driver’s own actions are shown to be the cause. A similar pattern played out in 2024, when Musk had to clarify that FSD was never even downloaded onto the Model 3 involved in a fatal Colorado DUI crash, despite a passenger’s claim that an “auto drive feature” was in use.

Tesla has not issued a separate statement on the Manhattan crash beyond Musk’s posts on X. The NYPD’s investigation is ongoing, and no cause for the driver losing control has been released.

Tesla’s two defunct flagship models are getting a big upgrade

Published

on

Tesla’s two recently-defunct flagship models, the Model S and Model X, are getting a big upgrade, according to the company’s Head of AI, Ashok Elluswamy.

Older Hardware 3 Model S and Model X vehicles have been the last major holdouts in Tesla’s Full Self-Driving v14 Lite rollout, and that wait now appears to be ending.

Tesla brings closure to flagship ‘sentimental’ models, Musk confirms

At Tesla’s Cybercab launch, AI chief Ashok Elluswamy told Ryan McCaffrey that he thought the S and X build “was supposed to go out last week.” Evidently, Elluswamy expects the suite to be rolled out to those HW3 Model S and Model X very soon:

Those cars are not the current Model S and Model X, which already ship with Hardware 4. They are the pre-refresh flagships built around Tesla’s older Autopilot computer, often called HW3 or AI3.

Tesla stopped putting that computer in new vehicles years ago, which is why owners treat these S and X cars as a closed generation. Model 3 and Model Y vehicles on the same computer began receiving v14 Lite in late June 2026 and saw a wider North American expansion in July. South Korea followed as an early international market. The S and X versions of the same software never joined that wave.

v14 Lite is Tesla’s way of squeezing the current v14 driving stack onto hardware that cannot run the full AI 4 model. The company describes the process as distillation: behaviors learned on the newer computer, including reinforcement learning and offline models, are compressed so the older chip and cameras can use them as a guide.

Early descriptions put the distilled network at roughly 15 percent of the original size. The result is still supervised Level 2 driving. Tesla has been clear that HW3 cannot support unsupervised Full Self-Driving or robotaxi operation because of memory and bandwidth limits.

The feature list is what made the wait so frustrating for S and X owners, as plenty of new features are to be shipped with it.

Official notes for the first Lite build, firmware 2026.20.5.1, added parking, unparking, and reversing; arrival options for a parking lot, street, driveway, or curbside; speed profiles that stay available at all times; and start-from-park engagement. Tesla also claimed better handling of merges, forks, pedestrians, traffic lights, and cut-ins, plus fewer false slowdowns and smoother lane centering.

A mid-July follow-on build, 2026.20.6.10, added more of the Hardware 4 interface, including a standalone Self-Driving app and the ability to start a trip from Park without a brake-pedal confirmation.

Elluswamy called that version the one “likely going to wide release.”

That wide release already reached most other HW3 cars in the United States and Canada. International timing still depends on regional validation and regulatory approval. For S and X owners, the remaining work appears to be model-specific validation rather than a new software stack.

There is no official Tesla changelog or build number for those two models yet, only Elluswamy’s offhand timeline. Some HW3 drivers who already have Lite report large gains over v12.6; others have described new indecision or phantom braking. The next test will be whether the same software lands cleanly on the older flagships that have waited the longest.

This tiny Tesla Cybertruck adjustment has big advantages

Published

on

Yesterday, we reported on Tesla Cybertruck getting some major adjustments from a manufacturing standpoint in an effort to make the all-electric pickup more cost-effective, more reliable, more serviceable, and more easily produced.

Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup

One of those changes was the addition of a self-reinforcing polypropylene aero shield that sits underneath the truck. Previously, Tesla utilized aluminum for this, but the self-reinforcing polypropylene was more durable while also being cheaper and lighter.

Tesla has revealed another small change it made to the Cybertruck, and it has to do with the side repeater cameras.

Tesla does not wait for a new model year to improve its vehicles. On September 8, Cybertruck lead engineer Wes Morrill posted side-by-side photos of an updated side repeater camera housing now rolling off the line at Gigafactory Texas.

The triangular camera pod mounted on the front fender looks almost identical at first glance. A closer look reveals a revised contour that uses the air already flowing around the truck to keep the lens clearer in rain and road spray.

The side repeater cameras sit in an exposed position on the Cybertruck’s angular stainless-steel body.

In wet weather, they readily collect water droplets that can degrade the image Autopilot and Full Self-Driving use for lane changes and blind-spot monitoring. Early production trucks sometimes left owners wiping lenses by hand or accepting temporary restrictions on driver-assistance features.

Tesla has added washers to cameras on certain other models and on Cybercab prototypes, but those active systems add cost, complexity, and extra potential leak points.

The new housing solves the problem with passive geometry. Subtle changes in the surround create localized airflow disturbances as the vehicle moves. Those eddies physically push water droplets away from the optical surface. Morrill called the result “pure vision improvement” achieved at “no cost penalty.” Once the production mold is updated, every subsequent part costs the same as the original.

The advantages compound quickly. Clearer cameras in rain improve the reliability of driver-assistance features precisely when they are needed most. The design consumes no extra energy and introduces no new failure modes.

New Cybertrucks built after the tooling changeover receive the updated part automatically. Some owners of trucks delivered as late as June 2026 have already confirmed they received the revised housing. Retrofit questions have appeared in replies, and the cameras appear electrically compatible, though Tesla has not announced an official service program.

A few millimeters of reshaped housing will not make headlines the way a new battery pack does, but these changes are incremental and increase the Cybertruck’s effectiveness as a vehicle over time.

This improvement illustrates how Tesla continues to refine the Cybertruck after volume production began. Better wet-weather vision, zero added cost, and no extra hardware add up to a meaningful gain in everyday usability and safety.
