This week Tesla updated their iPhone app to version 4.21.5. The updated features include a new Loot Box design and a notice to Canadians using their Superchargers. Tesla also hints at several upcoming features including Boombom v2.
Tesla's Model Y With Hardware 4.0 Doesn't Include Radar: We Take a Look at Why
Tesla's Model Y with HW4 is coming without radar
Tesla
As Tesla continues to redefine the automotive industry, insiders have revealed that the company's upcoming Hardware 4.0 (HW4) will not include the radar module in its Model Y vehicles, at least not initially. This marks a shift in the company's approach towards autonomous driving, relying more heavily on vision-based systems. This strategic decision builds on the recent introduction of HW4 in the luxury Model S and Model X models.
Previously, the integration of HD radar in the Model S and Model X indicated an evolution in the company's Full Self-Driving (FSD) hardware.
Tesla Reduces FSD Beta Suspension Duration With FSD Beta 11.4.2
Tesla has reduced the FSD suspension to one week with FSD Beta 11.4.2
Tesla
Tesla is again modifying the Full Self Driving (FSD) Beta suspension policy. Initially, the system, which is based on a strike policy, suspended users until Tesla reset strikes globally, which ranged from about every three to nine months. The driver has up to three strikes for vehicles without a cabin camera and five for those equipped with them.
More recently Tesla changed their policy to reset FSD suspensions on an individual basis after "approximately two weeks," according to Tesla. But with the introduction of FSD Beta 11.4.2, Tesla has now reduced the suspension interval from two weeks to approximately one week.
Tesla and Ford Forge New Partnership: Ford To Incorporate Tesla Charge Port (NACS) in Future EVs
Ford will add a Tesla (NACS) port to its future EVs
Tesla
In a move that attests to Elon Musk's words on fostering industry collaboration over competition, Tesla and Ford have announced a partnership to enable the latter's electric vehicles access to Tesla’s extensive Supercharger network.
Contrary to earlier speculations that Tesla's move to open its proprietary charging connector might be a futile attempt at standardization, Ford has embraced the North American Charging Standard (NACS) - Tesla's charging system. With this, Tesla’s charging plug design, known for some advantages over the current CCS standard, might start gaining traction across the North American EV sector.

For Tesla owners, the auto wiper system has been a contentious feature. Loved by some for its attempt at autonomous convenience yet criticized by others for its hit-or-miss performance, the system has often had trouble with extreme light conditions or misty weather. Now, Tesla has introduced v4 of their autowipers system that aims to correct past issues and enhance the user experience.
The updates come via the new Full Self-Driving (FSD) Beta 11.4.2, as reported by Tesla hacker @GreenTheOnly. While release notes didn't indicate changes, Green pointed out significant differences under the hood.
Tesla to Deliver Cars at 50% Charge, Offers 150km Free Supercharging
Tesla will now give owners a 150km Supercharger credit
Tesla
Tesla has recently come up with a new way of doing things when it comes to delivering cars. The company claims this change has been made to align with some new rules in the industry. In the past, Tesla always delivered cars with a full charge. Now, they are to be delivered with only half charge.
When electric vehicles are being transported from one place to another, having them fully charged can pose a risk. Keeping the state of charge (SOC) at 50% during shipment reduces the chances of battery fires. This practice is not new. Other battery-operated devices, like e-bikes, are also shipped at a lower SOC for the same safety reasons.
Tesla Model 3 Refresh Reveal Rumors Coincide with Elon Musk's China Visit
Is Tesla getting ready to unveil the refreshed Model 3?
ffiarpg/Reddit
Tesla CEO Elon Musk's recent visit to China, his first in three years, has set the stage for widespread conjecture around the unveiling of the revamped Tesla Model 3. Dubbed Project Highland, this model refresh has been a topic of discussion for some time. Industry insiders believe Musk's significant stop at the Shanghai Gigafactory might be strategically timed to coincide with a potential sneak peek of the new Model 3 design.
Tesla Screen Size Comparison for All Tesla Models, Including Size, Resolution and Aspect Ratio

Tesla
Tesla is a pioneer in the automotive industry, and one of the most defining features of its vehicles is the use of large touchscreens. These screens are a central hub for most vehicle functions, including music, vehicle settings, navigation, and more. Tesla's commitment to a minimalist and user-friendly design is evident through integrating these screens, which have become iconic in electric vehicles.
Between 2012 and 2020, the Model S and Model X were equipped with vertical screens, which stood out due to their impressive size and orientation.
Tesla’s latest vehicles, including the Cybertruck, Cybercab, and the refreshed Model Y, now feature a front bumper camera. However, as of FSD v13.2.8, the Cybertruck’s bumper camera remains unused for FSD and primarily serves as a helpful tool for parking and off-road driving.
With bumper cameras becoming more common across Tesla’s lineup, the question remains: will they eventually become a necessary component for Unsupervised FSD, or are they simply an added convenience for now?
Actually Smart Summon Needs Bumper Vision
Not a Tesla App
Every Tesla model that has the ability to use Actually Smart Summon occasionally rolls slightly forward or backward before exiting a parking stall. This movement helps the vehicle get a better view of what’s directly beneath the front lip of the hood before proceeding.
However, this behavior has led some vehicles to make contact with walls or posts, prompting the NHTSA to launch an investigation into Actually Smart Summon. The simple solution is to mount a lower front camera that allows the vehicle to see what’s directly in front of it when it wakes up.
The Cybertruck currently lacks access to Actually Smart Summon—or any Summon functionality, for that matter. Tesla hasn’t announced when the vehicle will receive one of its most advanced autonomy features. Given the vehicle’s height and its larger front blind spot, the delay likely stems from the need to integrate the bumper camera for improved visibility.
At the end of the day, Actually Smart Summon is essential for Unsupervised FSD. A fully autonomous vehicle must be capable of navigating crowded parking lots, reaching pickup points, and parking itself without human intervention.
Training Data and Cameras
We already know that adding a new vehicle to FSD can take months—but what about integrating training data from an entirely new camera and perspective? That process could take even longer, especially with a vehicle like the Cybertruck, which is larger and wider than Tesla’s other models.
We also know that the Cybercab—set to launch in Austin in just a few months—features a bumper camera to improve visibility below the front lip. Tesla doesn’t add new components without purpose; every part, from the camera and wiring to the housing and engineering, represents a calculated investment.
Given this, it’s reasonable to expect that Tesla is already using bumper camera data from the Cybertruck—and soon, the refreshed Model Y—to train an updated FSD model. Whether this model is focused on parking lot navigation and Actually Smart Summon or expands to broader FSD improvements on city streets and highways remains to be seen.
Compute and AI5
Tesla has already stated that the AI4 computer has unused compute power, but they’re running into memory limitations in future FSD builds due to the sheer volume of incoming data. That said, Tesla has hinted at optimizations to better manage memory on AI4.
Would integrating data from an additional camera overwhelm the system? Probably not in terms of compute, but memory efficiency remains a key area for improvement—especially as Tesla plans to triple both the model size and context window in upcoming FSD versions.
On the other hand, the Cybercab is set to launch with its own unique, more powerful AI5 computer. At the We, Robot autonomy event in October, Elon Musk confirmed that AI5 was designed for redundancy and higher safety. Tesla has been working on parallelizing FSD computations for some time—but we’ll explore that in a separate article.
Wrapping it Together
Putting it all together: the bumper camera has arrived, and Tesla doesn’t add hardware without a purpose. While it’s not yet in use for FSD, Tesla is likely gathering footage to train future models. The AI4 computer has the compute power to handle an additional data stream—but will Tesla actually integrate it?
If we were to go out on a limb, we’d say that Unsupervised FSD will likely require a bumper camera to be part of the Robotaxi network, but there’s another compelling reason. Tesla currently offers Supervised FSD for subscription and sale - but you can no longer buy FSD the way it used to be marketed. That changed back in September 2024, when they made adjustments to all their websites globally to list Supervised FSD as the product and feature that was being sold. That could have an impact on Tesla’s future plans with how they offer Unsupervised vs Supervised FSD.
So, will a bumper camera be necessary? We think so. Will it be a retrofit? Possibly. Tesla has already confirmed that they will retrofit HW3 vehicles with improved hardware in the future, meaning that other FSD hardware upgrades aren’t completely off the table.
However, retrofitting a bumper camera is complex, requiring extensive disassembly, wiring through the frunk, firewall, and into the AI computer. It’s possible that the camera will primarily be used for low-speed parking lot maneuvers—where supervision will be required—while Unsupervised FSD will only be available while driving on city streets and highways. The largest issue is simply what happens if the vehicle was asleep, and it can now only leave by driving forward — where it has a large blind spot.
While the exact role of the front bumper camera remains uncertain, its presence in newer models suggests it could be critical for a. fully autonomous vehicle. Whether it becomes a requirement for the vehicle to start driving from a parked position without anyone inside the vehicle, or whether it’ll only be required in parking lots or even to become a part of the Robotaxi network remains to be seen.
Tesla’s latest software update, version 2025.2, brings new features to Service Mode, continuing the trend of improving in-vehicle diagnostics.
Currently, this feature is only available for vehicles with AMD Ryzen infotainment systems and requires Service Mode+, which is a subscription service aimed at technicians. Intel-powered vehicles aren’t supported yet, but we expect this feature to roll out to them as well unless hardware limitations prevent it.
Thanks to Spencer for providing an image of the panel in action.
Signal Viewer Panel
While update 2025.2.6 adds four service mode improvements, including updates to brake burnishing, charge port calibration, and noise recording panel improvements. In this article, we’ll focus on the new signal viewer panel.
This new panel offers a live data feed from selectable vehicle sensors. You select the signals you’re interested in and it’ll plot the signal on a graph. In addition to allowing you to view real-time signal data, it also allows you to record them.
The signals are searchable and can be easily added or removed from the panel. You can track up to 10 sensors, and the UI allows three of them to be viewable at once.
However, this is Service Mode and it’s more than just pretty looks. You can really dig down into these charts. You can pan them left and right through time, and tapping a specific point shows the exact value of that signal. The panel also supports pinch-to-zoom, enabling you to adjust the time scale across all panels simultaneously.
This feature is exclusive to Service Mode+, which requires a subscription to Tesla’s ToolBox3 software and a connection to a computer. It’s designed to help technicians diagnose issues related to signal quality, noise in the vehicle’s electrical systems, and signal variance in components during driving.
