Tesla’s new 2020.40.0.4 Software Update has been released to owners, and a variety of new features were added to make life easier for drivers. Speed Assist Improvements join new security functionalities, along with fresh accessibility features to make driving a Tesla safer and more luxurious.

While the electric automaker rolls out updates in a frequent fashion, this new software comes with multiple functionalities that are entirely new to drivers. Other updates could include one or two features that are simply improvements to already existing characteristics. However, 2020.40.0.4 includes multiple features that Tesla has not included in past updates.

Speed Assist Improvements

Tesla vehicles will now use the external cameras on the car to detect speed limit signs. This will help improve the accuracy of speed limit date for highways, but it will also help vehicles travel at appropriate speeds.

In the past, some owners have complained that their vehicles are not recognizing the speed limits in certain regions. California drivers were having relatively non-existent issues with the functionality, but drivers in other parts of the United States were reporting several issues with their cars traveling at the correctly intended speeds.

CEO Elon Musk responded that the issues were of “high priority,” and that Tesla was addressing them.

It appears that the functionality has been improved and fixed. The release notes state:

“In addition to local roads, Speed Assist now leverages your car’s cameras to detect speed limit signs to improve the accuracy of speed limit data for highways. As usual, to adjust Speed Assist settings, tap Controls > Autopilot > Speed Limit.”

Additionally, drivers with different Infotainment systems will have differing capabilities.

Notes for MCU2 drivers state:

“Speed Assist now leverages your car’s cameras to detect speed limit signs to improve the accuracy of speed limit data on local roads. Detected speed limit signs will be displayed in the driving visualization and used to set the associated Speed Limit Warning. As usual, to adjust Speed Assist settings, tap Controls > Autopilot > Speed Limit.”

MCU1 users will have slightly fewer capabilities, according to their notes, which say:

“Speed Assist now leverages your car’s cameras to detect speed limit signs to improve the accuracy of speed limit data on local roads. As usual, to adjust Speed Assist settings, tap Controls > Autopilot > Speed Limit.”

The functionality is availabel on all four currently released Tesla models and requires HW 3.0 to be used.

Priority Bluetooth Device

Tesla vehicles will now connect to one Bluetooth device that has been defined as the “priority device,” according to the new update. This will stop confusion between two owners whose phones or devices are both synced to the vehicle. One phone will be considered the “priority” device, and will automatically connect. It is available for all four vehicles.

“To avoid connecting to the wrong nearby phone, you can now set your priority Bluetooth device. Your car will attempt to connect to the priority device associated with the profile selected before it attempts to connect to other paired phones. To set your priority device, tap the Bluetooth icon on the top of your touchscreen, select your preferred phone and tap Priority Device.”

Mobile App – Vent Windows

This feature is pretty self-explanatory. It is only available for the Model S, however.

“You can now vent all of your windows from the Tesla mobile app.

Note: this feature requires the Tesla mobile app version 3.10.0 or later.”

Glovebox PIN

A great security addition for owners, the Glovebox will now be locked until a four-digit PIN number is entered. A glovebox is a great place for sensitive information like insurance or vehicle titles. Tesla adding this feature should give owners peace of mind. It is available on all four cars.

“Protect the valuables in your glovebox with a 4-digit PIN. Tap Controls > Safety & Security > Glovebox PIN on the touchscreen to create your PIN.”

Charge Port Inlet Heater

Model 3 and Model Y owners can enjoy a defrosted charge port thanks to an inlet heater that will remove any ice or snow from the inside of the mechanism. It can be turned on through the Tesla mobile app, so owners won’t have to go out into the cold weather to get things cleared up for when they need to charge.

“Your car can now use the charge port inlet heater to help defrost the inside of the charge port. The charge port inlet heater can be activated in cold ambient temperatures by enabling preconditioning using the mobile app, activating the rear defrost button on the vehicle’s touchscreen, or preconditioning the vehicle using scheduled departure.”

Elon Musk says your Tesla will start to learn your individual preferences

Published

Elon Musk said today on X that Teslas will start to learn your individual preferences. This is something that he seemed to hint toward earlier this month when he said parking was by far the biggest reason drivers intervene with Full Self-Driving.

Musk made the comment in response to notable Tesla influencer Whole Mars, who said that his vehicle will sometimes disobey the settings he has enabled for his car. He responded to the post, stating that “The car will start to remember your specific interventions and match each person’s individual preferences.”

This is something that could be perhaps one of the biggest ways Tesla could minimize or even work closer toward eliminating interventions altogether. While FSD does a lot of things really well, many people intervene a vast majority of the time not due to major or critical safety errors.

Instead, many take over because the car is doing something that they do not like as a preference; it might park in a parking spot that is not preferred by the driver, it might linger too long in the left lane on the highway (a personal favorite), or it could even take a route that the driver does not like.

These all lead to interventions, but they are not triggered by a major safety issue. Instead, it’s just preference.

If Teslas could start to learn the personal preferences of the person who owns them, interventions will truly begin to be less frequent. Some of this is already pretty evident, in my opinion. Teslas use a neural network to learn behaviors and accumulate data to improve performance.

For months now, we’ve tracked FSD’s performance at “Except Right Turn” stop signs, something that is very common in Pennsylvania, but many of our readers located in other parts of the U.S. have never heard of. FSD handles one Except Right Turn stop sign very well, one that I travel past frequently. Others that I do not navigate through as often do not have as confident a performance. It seems like the cars might already be doing this to an extent.

That example is also for something that is a street sign and not necessarily a driver preference; however, I still feel it is worth mentioning because it only handles that commonly passed Except Right Turn stop sign with true confidence. Others it still seems to struggle with.

This could be one of Tesla’s big moves toward full autonomy, and it could be a pathway to truly unsupervised driving. Every day, millions of cars on the road travel at a human driver’s personal preferences with no incident. Why can’t autonomous vehicles still cater to a passenger’s preferences while being autonomous? Tesla seems to have the idea that it would be possible.

Ron DeSantis calls out media bias in Tesla crash coverage

Florida Governor Ron DeSantis has sharply criticized legacy media outlets for what he describes as selective and biased reporting on vehicle accidents involving Tesla. In a recent X post, DeSantis questioned why headlines routinely spotlight the Tesla brand in crash stories, even when human error is the clear cause, while similar incidents with other automakers often receive generic treatment.

A prime example is the June 19, 2026, fatal crash in Katy, Texas. A Tesla Model 3 driven by Michael Butler struck a brick home at high speed, killing 76-year-old Martha Avila inside. Initial reports and headlines prominently featured “Tesla crash” and referenced the driver’s claim that an automated driving-assistance system was engaged.

Many outlets quickly speculated that Full Self-Driving or Autopilot were the cause of the crash, immediately blaming the suites for the accident shortly after it happened.

However, Tesla responded shortly after the accident with vehicle data that showed Butler manually overrode the system by pressing the accelerator to 100 percent, reaching 73 MPH in a residential area, more than double the speed limit. The accelerator remained floored after impact.

Tesla finally clarifies fatal Texas crash, confirms driver manually overrode acceleration

The National Transportation Safety Board (NTSB) later confirmed these findings, and Butler now faces manslaughter charges. His phone searches also included queries like “Tesla FSD too timid,” suggesting he may have intervened aggressively. Despite this, many headlines continued to center Tesla’s technology rather than the driver’s actions.

DeSantis highlighted a Washington Post headline, which was labeled, “Newly released photo shows wreckage of Tesla crash that killed grandmother.”

The subheadline noted the driver overrode assistance and floored the accelerator, yet the brand name dominated the framing. He asked whether legacy outlets typically name the make of a car in routine crashes or reserve that treatment for Tesla to push a narrative.

This pattern appears widespread. Crashes involving Ford, Chevrolet, or Toyota vehicles frequently appear as “pickup truck slams into home” or “fatal car crash kills pedestrian” without brand specifics, especially absent new technology angles.

High-profile Ford F-150 or Chevy Silverado incidents tied to large sales volumes often escape brand-callout scrutiny. In contrast, Tesla stories consistently lead with the manufacturer, amplifying perceptions of risk despite data showing strong overall safety performance:

Tesla’s own 2025 Impact Report indicates vehicles using FSD logged 0.19 major incidents per million miles, roughly eight times fewer than the U.S. average. Models like the Model Y also rank among the safest in IIHS and NHTSA testing for occupant protection. Critics argue disproportionate coverage ignores these statistics and driver behavior factors, such as younger or more aggressive Tesla owners in some studies.

DeSantis frames this as part of a broader political agenda against innovative American companies like Tesla. By consistently naming Tesla while downplaying others, media outlets risk eroding public trust and shaping perceptions detached from the evidence of human error in most cases.

As autonomous technology evolves across the industry, consistent and factual reporting will be essential to separate real safety concerns from narrative-driven coverage.

Tesla enters two new markets on two different continents in one week

Published

on

Tesla entered two new markets this week by advancing its presence in Latvia (Europe) and officially launching operations in Uruguay (South America), marking a rapid dual-continent expansion.

These moves underscore the company’s strategy to tap into emerging EV markets with supportive policies, renewable energy grids, and growing demand for sustainable transport.

Latvia: Strengthening the Baltic Footprint

In Latvia, Tesla has built on its earlier registration of Tesla Latvia SIA in late 2025 with recent steps toward full operations, including job postings for a service center and representation in Riga. This aligns with broader Baltic expansion following Lithuania’s model of pop-up stores and service centers.

EV penetration in Latvia stands at around 7 percent for BEVs in new passenger car registrations. 2025 data showed 1,602 BEVs out of about 22,500 total, or 7.1 percent, with combined plug-ins nearing 19 percent. Growth has been steady but below the European average, supported by government subsidies and infrastructure development. Tesla models like the Model 3 lead local EV registrations.

Vehicles for the Latvian market will likely be sourced from Gigafactory Berlin or Gigafactory Shanghai. Charging infrastructure is robust for the region as well, with over 400- 2,000 public points, with Tesla Superchargers in Riga, Jūrmala, and along Via Baltica routes offering up to 250 kW.

Uruguay: Third South American Country

Tesla teased its Uruguay arrival with “Estamos llegando,” or, “We are arriving,” on social media, followed by an official presentation scheduled for mid-July.

Uruguay boasts one of Latin America’s highest EV penetrations, with battery-electric vehicles exceeding 20 percent market share recently, driven by tax incentives, high fuel prices, and a nearly 95-100 percent renewable electricity grid. Hundreds of Teslas already operate via grey imports, but official sales bring warranties, service, and support.

Vehicles will be imported from Gigafactory Shanghai, enabling competitive pricing for Model 3 and Model Y. Charging plans include Supercharger development alongside existing infrastructure, leveraging the country’s green energy advantage for affordable operation.

Tesla’s Dual Continent Expansion

Tesla’s simultaneous push into Latvia and Uruguay demonstrates efficient scaling: prioritizing service and infrastructure first, then direct sales in high-potential niches. In Europe, it fills Baltic gaps; in Latin America, it counters Chinese dominance while leveraging renewables.

This dual move signals Tesla’s ambition to accelerate global EV adoption amid varying regional paces. By addressing local needs, like subsidies in Latvia or incentives and green grids in Uruguay, Tesla not only boosts volumes but advances its mission of sustainable energy.

For investors and consumers, it highlights resilience and opportunity in diverse markets, potentially paving the way for further growth in underserved regions. With strong fundamentals in both, these entries could yield long-term gains as EV transitions mature worldwide.
