Tesla's Model Y Hardware 4 infotainment system has been reviewed by one of the most notorious Tesla enthusiasts, and it's a surprising outcome. Following a series of tweets (or Xs) from renowned Tesla hacker @greentheonly, it has come to light that the HW4 unit sports less RAM and storage than its predecessor, Hardware 3 on the infotainment side (MCU).

This change doesn't seem to make much sense, given Tesla's track record of continuously improving the product. It has sparked a debate about the potential impacts and motivations behind the change.

HW4 vs HW3: A Comparison

The latest information revealed that the HW4 infotainment system in the Model Y comes with 8GB of RAM and 128GB of storage, exactly half of what the HW3 units offer. This significant reduction has led to questions about the possible implications on user experience, including the inability to support gaming services like Steam, which requires 16GB of RAM on the Model S and X. It's certainly possible Tesla finds a way to run Stream on less RAM, but it's unlikely given that Steam is run in a virtual machine.

Interestingly, despite these changes, the Central Processing Unit (CPU) between HW3 and HW4 remains the same. Furthermore, @greentheonly, who did an in-depth breakdown of HW4 last month, confirmed that both HW3 and HW4's infotainment side using the Advanced Micro Devices (AMD) CPU is susceptible to voltage glitching attacks. The surge attacks were revealed by a group of hackers, who call themselves researchers, last week.

Impacts on Performance

While concerns about reduced specifications are valid, some users report that the HW4 Model Y is incredibly responsive. @greentheonly attributes this to the model's newness, free from accumulated unnecessary data known as "cruft."

Reasoning Behind the Change

The decision to reduce the RAM and storage in HW4 seems perplexing to some Tesla fans, leading to speculation about Tesla's rationale for this move. However, cost considerations could be at the core of this decision. These changes were identified in Model Y HW4 units manufactured in both the Texas and Fremont factories.

Community Reactions

Tesla's community has shown mixed responses to the revelations. Some express disappointment at an apparent downgrade, while others remain hopeful about the system's optimized performance despite the reduced specifications. The discussion on TX.com also raised questions about why the Model Y configuration does not follow the same hardware pattern as Model S/X and why there are no performance trims for Infotainment.

The new findings about Tesla's Model Y HW4 infotainment with reduced specifications may seem like a step back, but the actual impact on user experience remains to be seen.

Whether Tesla's engineers have found a way to enhance the system with reduced resources or if this move is driven solely by cost considerations will likely become more apparent with time and usage. The dialogue initiated by @greentheonly provides valuable insights, though, and will continue to be a focal point for those interested in understanding Tesla's evolving technology and strategic decisions.

Tesla Looks to Add New Full Self-Driving and Premium Connectivity Plans in Canada

Tesla may soon support a monthly FSD subscription and the Premium Connectivity annual plan for Canadian customers. The possible move was discussed on X as Tesla’s Vice President of Public Policy and Business Development, Rohan Patel, responded to inquiries.

FSD Beta Subscription in Canada

The potential introduction of the FSD beta subscription in Canada represents a notable evolution in Tesla’s FSD pricing. The monthly subscription is available in the U.S. for $200 USD per month, this service allows Tesla owners to access the company’s suite of Advanced Driver Assistance Systems (ADAS). Considering currency exchange rates, this could translate to around $270 CAD monthly for Canadian consumers. This pricing strategy aims to make Tesla’s ADAS features more accessible, offering flexibility to subscribe or unsubscribe based on individual needs and circumstances, such as seasonal driving preferences. Currently, Canadian customers only have the option to buy FSD in full at $16,000 CAD.

While a subscription service for FSD Beta may allow more drivers to try out the technology, it will also assist Tesla in gathering more information and improving the system faster. The more miles clocked by FSD, the more the system learns.

Premium Connectivity Annual Plan

Alongside the FSD beta, Tesla is exploring the possibility of offering an annual subscription model for its Premium Connectivity service in Canada. Tesla started offering an annual subscription for Premium Connectivity in the US back in 2022 at $99.99, representing a 20% savings. Premium connectivity offers drivers additional features such as Live Traffic Visualization, Satellite-View Maps, and streaming services such as Netflix, Spotify and YouTube. The anticipated price for Canadian subscribers is set to be around $139.99 annually, offering a savings opportunity compared to the current monthly subscription rate of $13.99 CAD.

Patel's engagement on X highlights Tesla's proactive approach to addressing potential legal and regulatory barriers that might impede the introduction of these services in Canada. He committed to investigating these issues, underscoring Tesla's dedication to its Canadian customer base.

Strategic Investments and Enthusiastic Community

Tesla's plans for Canada go beyond just offering new subscription services. The company has made significant investments in manufacturing, engineering, and supply chain operations in the country.

Tesla FSD Beta v12 Auto Parks, Completes U-Turns, But Removes Traffic-Aware Cruise Control Ability

Tesla's FSD Beta version 12.2.1, update 2023.44.30.20, recently started going out to some owners, which resulted in more videos posted on X. There are several examples of amazing technology at work, but also evidence that more work is needed.

Ashok Elluswamy, Tesla's Director of Autopilot Software, recently highlighted the sophistication of FSD Beta v12 on X, emphasizing how the system's end-to-end approach is tackling complex driving scenarios with remarkable ease. His response came to a video of FSD maneuvering around a large puddle.

FSD V12 Does U-Turns

One of the standout features of FSD Beta v12 is its ability to execute U-turns seamlessly when required by the route. This is where real-world examples show the good and the bad of this highly advanced maneuver come into play. X user AI DRIVR, an account posting several high-quality videos of V12.2.1 in action, demonstrates a flawless U-turn.

Unfortunately, not all U-turns posted on X are as pretty; Randolph Kim has been experimenting with several scenarios. While later videos showed better behavior with u-turns and roundabouts, the earlier attempts had to be disengaged.

Parking Mode / First Glimpse at Park Seek

During our first glimpse of FSD v12 during Musk’s livestream, we noticed a new behavior when the vehicle reached its destination. Instead of just stopping, the vehicle now pulled over to the side of the road. However, it looks like the newest release goes one step further.

In a video by ArthurFromX, the vehicle is navigating to a parking lot. Not only does the vehicle successfully navigate to the parking lot, but it hunts around for a spot and then successfully parks without any additional instructions.

This could be our first glimpse at Tesla’s upcoming Park Seek feature that will eventually let the vehicle drop you off at the door and then go park itself.

Return of the Snapshot Button

Tesla appears to have reintroduced the Snapshot button in this update, at least to some owners. The snapshot button allows drivers to send additional information to Tesla regarding Autopilot's performance. This feature and the existing voice command feedback option provide Tesla with invaluable data to improve the FSD system further.

Automatic Speed Offset

Another noteworthy addition is the Automatic Set Speed Offset feature, which grants the vehicle autonomy to adjust its speed based on factors such as road type, traffic flow, and environmental conditions. The video below shows this feature in action. The feature is turned off by default and it currently only applies to street-level roads, but it’s a shift toward more human-like behavior for FSD Beta.

TACC is No Longer Accessible

Recently, Tesla revised the Autopilot activation method to avoid confusion and offered drivers two choices — a single pull of the stalk to enable FSD Beta or the traditional two taps. However, with FSD Beta v12, drivers are now required to use the single pull method to activate Autopilot.

Traffic-Aware Cruise Control (TACC) has traditionally been one pull of the stalk and Autopilot two pulls, but with the new single-pull method to activate Autopilot, TACC becomes unavailable. This hasn’t been a big deal until the release of FSD v12. With v12 Tesla is now requiring FSD Beta to use the single tap activation method.

This means that if a driver chooses to use FSD Beta, then TACC is no longer accessible. The only way to enable it is to go into Controls > Autopilot and turn off FSD Beta and instead choose Autosteer (or TACC). However, if you wish to enable FSD Beta again later, then it requires the vehicle to be in Park. Switching between Autosteer and FSD Beta isn’t practical for drivers. For those who rely on TACC, this issue could be a significant disadvantage in this release.

Several drivers have praised FSD Beta v12’s ability to navigate complex situations, better decision-making, and smoother behavior. However, as with any cutting-edge technology, there have been instances where the system's responses have room for improvement, highlighting the importance of its continued development.
