Tesla has officially started deploying a software update activating its in-cabin radar, a feature that has been supported and expected for a few years, and one that may require a retrofit for some owners.
On Friday, Tesla began rolling out software update 2025.2.6, featuring the activation of its in-cabin radar located just above the passenger dome light. The company lists the feature in its owner’s manuals, noting that the cabin radar is currently only available for 2022 model-year Model Y units and later, though it’s also expected to roll out to refreshed Model 3 and Cybertruck units at some point.
Some have also said that they believe the refreshed Model S and Model X have been equipped with the radar hardware, so it’s possible these vehicles could also receive the feature. Tesla calls the feature the First-Row Cabin Sensing Update in the release notes for 2025.2.6, which also seems to be related to the company’s debut of the so-called 4D Radar in the new Model Y.
What does Tesla’s in-cabin radar do?
“Cabin radar can detect the presence of people inside the vehicle and use the measurements to determine occupancy,” Tesla writes in the owner’s manual. “Cabin radar supports certain vehicle and safety features, such as occupancy detection for the front passenger seat.”
The benefit of cabin radar is that it uses radio waves to detect objects and passengers inside the vehicle, and it can do so more precisely than the selfie camera when identifying what exactly is in the front and rear seats. Recently, Tesla has also highlighted the 4D radar system’s ability to pick up on things like the heartbeat of a pet or small child, offering an extra layer of safety for passengers.

In a video interview with Tesla Owners Silicon Valley earlier this week, the company’s Model Y Program Manager, Emmanuel Lamacchia, also detailed the 4D imaging radar, saying that it both detects and classifies passengers based on their size. This lets the system toggle necessary airbags and even take further precautions against passengers being left behind in the vehicle.
Eventually, Lamacchia says the system will be able to protect against a child or pet being left behind by sending a reminder to owners, turning on the HVAC system, rolling down the window, or even calling 911. The Model Y Program Manager says that these will be enabled in the refreshed model in Q3.
Tesla’s Lead Cybertruck Engineer said on X on Friday that, while incidents related to these issues are extremely low, their severity can be extremely high, pointing to the importance of the upcoming feature.
You can watch the full talk from Lamacchia and Tesla Owners Silicon Valley below, with the bit about the 4D in-cabin radar starting around 30:30.

Tesla Full Self-Driving displays impressive collision avoidance with semi
A Tesla on Full Self-Driving helped a driver avoid a collision with a semi by anticipating the truck’s movement.

Tesla Full Self-Driving has displayed incredible anticipatory measures in the past to avoid collisions from both oncoming cars and vehicles approaching from behind.
In a recent demonstration, the semi-autonomous driving functionality averted disaster as it confused the driver by taking a precautionary measure as an oncoming semi-truck started to drift into its lane. By the end of the occurrence, the driver knew why FSD did what it had done.

Full Self-Driving avoids disaster
In a video from X account @AIDRIVR, Full Self-Driving navigated as normal when it started to take an oncoming sharp left-hand curve a tad higher than usual.
Normally, the vehicle would stay in the lane, but this time, it started to drift toward the shoulder after what appeared to be a small reduction in speed.
AIDRIVR said he “wondered why FSD was taking this corner so wide,” but the answer quickly approached him from the other side of the road, proving once again that Tesla’s suite is a few steps ahead of even human drivers at times:

A semi-truck in the oncoming lane started to drift over the center line through this sharp turn.
With these large vehicles, these curves can sometimes prove to be better handled by taking the turn a tad wider, which means the large commercial vehicle will start to approach the middle yellow lines.
However, this is much to the chagrin of other drivers and can be a major inconvenience and safety hazard.
Full Self-Driving continues to show instances where it is predicting and anticipating the behaviors and actions of other drivers, keeping occupants in the Tesla safe by using certain tactics to avoid collisions.

Tesla CEO Elon Musk confirms Robotaxi will come to Saudi Arabia
Tesla Robotaxi will be in Saudi Arabia one day, Elon Musk confirms.

Tesla CEO Elon Musk confirmed during the Saudi-U.S. Investment Forum on Tuesday that the company’s Robotaxi platform would eventually land in the Kingdom of Saudi Arabia, essentially confirming the intention to grow a driverless fleet of vehicles outside of the United States.
This is the first time Musk has specifically confirmed Tesla’s intention to expand into Saudi Arabia, although based on the company’s plans, a global expansion is more expected than a confined Robotaxi platform that is limited to only the West.
Musk confirmed during the Investment Forum, where the U.S. agreed with the Saudis to a $600 billion investment pledge, that Robotaxi would eventually expand to the country. The CEO did not mention a specific timeframe, but Tesla is set to launch the Robotaxi platform in Austin, Texas, in June.
“Really, you can think of cars, or future cars, as being robots on four wheels. I think it will be very exciting to have autonomous vehicles here in the Kingdom, if you’re amenable.”

As Tesla’s Full Self-Driving suite is still supervised, it is expanding to other parts of the globe. Earlier this year, it made its way to China for the first time ever, with many giving rave reviews of the driver assistance platform.
Tesla plans to expand to Europe later this year, but the company is still awaiting regulatory approval from EU agencies, something that will likely take some time to complete.
The big takeaway is that the Robotaxi platform is not confined to a single model, like the Cybercab. Instead, Robotaxi could be any Tesla vehicle, as long as it is capable of unsupervised Full Self-Driving. This is something that will require Tesla to work with local authorities to first launch a Supervised version of the suite, which could then expand to the unsupervised FSD platform, enabling a Robotaxi network in the country.
Nevertheless, Tesla’s relationship with the Middle East seems to be good. The company recently launched the Cybertruck in Saudi Arabia, enabling customer orders just last month.

Additionally, Musk’s Starlink was recently given approval for both maritime and aviation use cases, expanding the relationship between the country and the CEO. This was also confirmed during the Investment Forum today.

Tesla is building Cortex 2.0 supercomputer facility in Giga Texas
The site was listed as the Central Campus Support facility, but recently, the filings have been updated as Cortex 2.0.

Tesla may already have a supercomputer cluster in the Giga Texas complex, but it seems like the electric vehicle maker is not done with its supercomputer plans just yet. Based on images taken of the Giga Texas complex recently, it appears that work is now underway to construct a new facility for Cortex 2.0, a companion to the site’s existing Cortex supercluster.
New Giga Texas Facilities
As per longtime Tesla Gigafactory Texas watcher Joe Tegtmeyer, Tesla has been constructing a facility on the North side of the complex for a few months now. Initially, the site was listed as the Central Campus Support facility, but recently, the filings have been updated as Cortex 2.0. So far, work is underway for the Cortex 2.0 building shell, though permits have already been filed for other parts of the upcoming facility.
The speed of the buildout for the Cortex 2.0 facility is rapid, with the drone operator estimating that the location may be operational as early as late this year. It would also not be surprising if Tesla ends up ramping its activities at Gigafactory Texas’ Cortex 2.0 supercomputer cluster sometime next year.
FSD Training and Beyond
Tesla’s heavy investments in its supercomputer clusters are expected to help the company develop and refine its self-driving system, which is currently deployed in non-autonomous form as Full Self-Driving (FSD) Supervised. Tesla is expected to launch a robotaxi service in Austin in a few weeks, though these vehicles are expected to use FSD Unsupervised, which would be fully autonomous.
Apart from FSD, Tesla’s Optimus program will likely require a substantial amount of computing power as well. Elon Musk has stated that Tesla should be able to build its first “legion” of Optimus robots this year, with production ramping next year. Considering these ambitious timelines, perhaps Giga Texas’ Cortex 2.0 facility would be fully busy as soon as it becomes operational.
Check out a recent drone flyover of the Giga Texas complex in the video below.
