Tesla’s self-driving future to take center stage at Autonomy Day: What to expect
Tesla’s Autonomy Day is starting in a few hours, and the anticipation among the electric car community is reaching a fever pitch. Elon Musk has promoted Autonomy Day over the past week, even lightly hinting that the event will “free investors from the tyranny of having to drive their own car.”
Tesla’s noted in its initial announcement that it will be providing investors a deep dive into its full self-driving initiatives. Several key Tesla executives involved in the development of the company’s full self-driving technology are expected to address investors at the event, including VP of Engineering Stuart Bowers, VP of Hardware Engineering Pete Bannon, and Sr. Director of AI Andrej Karpathy. More importantly, test drives on vehicles that are equipped with yet-to-be-released Autopilot and Full Self-Driving features are also expected to be conducted.
Apart from this information, Tesla has managed to keep the specifics of its upcoming autonomy event secret. With this in mind, here are some developments and features that we expect Tesla to showcase in Autonomy Day.
On April 22, Investor Autonomy Day, Tesla will free investors from the tyranny of having to drive their own car

Summon and Navigate on Autopilot Improvements
When Tesla brought back Full Self-Driving as an add-on for its electric cars, the company placed Navigate on Autopilot and Summon, two features that were previously part of Enhanced Autopilot, as part of the FSD suite. Tesla has since improved the features, with Enhanced Summon allowing vehicles to navigate a parking lot to find their owners, and Navigate on Autopilot being capable of changing lanes without any turn stalk confirmation. These features are still being improved by Tesla, and it would not be surprising if the company decides to showcase improved capabilities of Summon and NoA to investors on Autonomy Day.

Traffic Light/Stop Sign response and automatic city streets driving
A look at Tesla’s order page for the Model S, Model 3, and Model X shows that Full Self-Driving has two capabilities marked for release “later this year.” These are “Recognize and respond to traffic lights and stop signs” and “Automatic driving on city streets.” Both these features require Tesla’s neural net to be trained enough to recognize visual input at a level that is quite close to that of a human driver. Tesla appears to be taking steps towards this goal, as indicated by findings from hacker-enthusiast greentheonly, who found what appears to be stop line detection features in 2019.4. Tesla’s recent Autosteer Stop Light Warning, which prompts drivers to take over the vehicle’s controls if a red light is detected, also appears to be a step towards automatic city driving.
Back in the third quarter earnings call, Director of AI Andrej Karpathy noted that while Tesla had already trained larger, more advanced neural networks that work very well, the company is unable to deploy it to the fleet due to the limitations of its hardware. “We are currently at a place where we’ve trained large Neural Networks that work very well, but we are not able to deploy them to the fleet due to computational constraints,” he said. These limitations are expected to be rendered null and void by Tesla’s Hardware 3, which is also expected to be discussed on Autonomy Day.
New mobile app features
At the core of the Tesla experience is its mobile app. It allows customers to view the status of their vehicles, and as shown in videos from members of Tesla’s early access program, it is also a central part of Summon’s more advanced features. A Teslarati reader who is part of the early access program recently sent new screenshots of updates in the mobile app (3.8.3), such as Roadside Assistance as well, which allows owners to call the company for aid in the event of a flat tire, or similar emergencies.
Tesla Network test drives
Tesla’s endgame with its full self-driving feature is the Tesla Network, a ride-hailing service that utilizes a fleet of autonomous vehicles. Back in the Q3 2018 earnings call, Musk noted the Tesla Network will be competing with giants such as Uber and Lyft. The company made its intentions for the Tesla Network even clearer when it released leasing options for the Model 3. In its announcement, Tesla stated that customers cannot purchase their leased vehicles after their lease period is over since the company will be using the electric cars for the Tesla Network. With Tesla expected to showcase its full self-driving features in Autonomy Day, it will not be surprising if the company provides a teaser of what it’s like to experience the Tesla Network firsthand.
An emphasis on human vigilance
While Autonomy Day will be focused on the company’s full self-driving features, Tesla will likely continue to emphasize that its vehicles and their driver-assist features still require constant attention on the road in the near future. This is something that Elon Musk has teased previously at an appearance in ARK Invest’s For Your Innovation podcast when he described how Tesla’s full self-driving features will be feature-complete. “I think we will be feature complete — full self-driving — this year. I would say I am certain of that. That is not a question mark. However, people sometimes will extrapolate that to mean now it works with 100 percent certainty, requires no observation, perfectly. This is not the case,” Musk said. Thus, for the following years, at least, Tesla will likely focus on Level 4 autonomous solutions, which are capable of operating a vehicle without human input but are equipped with pedals and controls for manual overrides just the same.
Tesla’s Autonomy Day will be livestreamed by the company.

Tesla confirmed HW3 can’t do Unsupervised FSD but there’s more to the story
Tesla confirmed HW3 vehicles cannot run unsupervised FSD, replacing its free upgrade promise with a discounted trade-in.
Tesla has officially confirmed that early vehicles with its Autopilot Hardware 3 (HW3) will not be capable of unsupervised Full Self-Driving, while extending a path forward for legacy owners through a discounted trade-in program. The announcement came by way of Elon Musk in today’s Tesla Q1 2026 earnings call.
🚨 Our LIVE updates on the Tesla Earnings Call will take place here in a thread 🧵

The history here matters. HW3 launched in April 2019, and Tesla sold Full Self-Driving packages to owners on the understanding that the hardware was sufficient for full autonomy. Some owners paid between $8,000 and $15,000 for FSD during that period. For years, as FSD’s AI models grew more demanding, HW3 vehicles fell progressively further behind, eventually landing on FSD v12.6 in January 2025 while AI4 vehicles moved to v13 and then v14. When Musk acknowledged in January 2025 that HW3 simply could not reach unsupervised operation, and alluded to a difficult hardware retrofit.
The near-term offering is more concrete. Tesla’s head of Autopilot Ashok Elluswamy confirmed on today’s call that a V14-lite will be coming to HW3 vehicles in late June, bringing all the V14 features currently running on AI4 hardware. That is a meaningful software update for owners who have been frozen at v12.6 for over a year, and it represents genuine effort to keep older hardware relevant. Unsupervised FSD for vehicles is now targeted for Q4 2026 at the earliest, with Musk describing it as a gradual, geography-limited rollout.
For HW3 owners, the over-the-air V14-lite update is welcomed, and the discounted trade-in path at least acknowledges an old obligation. What happens next with the trade-in pricing will define how this chapter ultimately gets written. If Tesla prices the hardware path fairly, acknowledges what early adopters are owed, and delivers V14-lite on the June timeline it committed to today, it has a real opportunity to convert one of the longest-running sore subjects among early adopters into a loyalty story.

Tesla 2026 Spring Update drops 12 new features owners have been waiting for
Tesla announced its Spring 2026 software update, and it’s the most feature-dense seasonal release the company has put out. The update covers twelve named changes spanning FSD, voice AI, safety lighting, dashcam storage, and pet display customization, among other things.
The centerpiece for owners with AI4 hardware is a redesigned Self-Driving app. The new interface lets owners subscribe to Full Self-Driving with a single tap and view ongoing FSD usage stats directly in the vehicle.
Grok gets its biggest in-car upgrade yet. The update adds a “Hey Grok” hands-free wake word along with location-based reminders, so a driver can now say “remind me to pick up groceries when I get home” without touching the screen. Grok first arrived in vehicles in July 2025, but each update has pushed it closer to genuine daily utility. Musk framed the broader vision clearly at Davos in January, saying Tesla is “really moving into a future that is based on autonomy.”
On safety, the update introduces enhanced blind spot warning lights that integrate directly with the cabin’s ambient lighting, building on the blind spot door warning that arrived in update 2026.8.
Dog Mode has been renamed Pet Mode and now lets owners choose a dog, cat, or hedgehog icon and add their pet’s name to the display.
Dashcam retention now extends up to 24 hours, up from the previous one-hour rolling loop, with a permanent save option for any clip. Weather maps now show rain and snow with better color differentiation and include the past hour of precipitation data along the route.
Tesla has now established a clear rhythm of two major OTA pushes per year. As with last year’s Spring update, that cycle started taking shape in 2025 with adaptive headlights and trunk customization. The 2025 Holiday Update then added Grok to the vehicle for the first time. This Spring follows that structure: the Holiday update introduces new architecture, and the Spring update broadens it across the fleet.
Two notable features still did not make it. IFTTT automations, which launched in China earlier this year, were held back from this North American release for unknown reasons, and Apple CarPlay remains absent, reportedly still delayed by iOS 26 and Apple Maps compatibility issues.
Below is the full list of feature updates released by Tesla.

Tesla mobile app shows signs of upcoming FSD subscriptions
It appears that Tesla may be preparing to roll out some subscription-based services soon. Based on the observations of a Wales-based Model 3 owner who performed some reverse-engineering on the Tesla mobile app, it seems that the electric car maker has added a new “Subscribe” option beside the “Buy” option within the “Upgrades” tab, at least behind the scenes.
A screenshot of the new option was posted in the r/TeslaMotors subreddit, and while the Tesla owner in question, u/Callump01, admitted that the screenshot looks like something that could be easily fabricated, he did submit proof of his reverse-engineering to the community’s moderators. The moderators of the r/TeslaMotors subreddit confirmed the legitimacy of the Model 3 owner’s work, further suggesting that subscription options may indeed be coming to Tesla owners soon.
Did some reverse engineering on the app and Tesla looks to be preparing for subscriptions? from r/teslamotors
Tesla’s Full Self-Driving suite has been heavily speculated to be offered as a subscription option, similar to the company’s Premium Connectivity feature. And back in April, noted Tesla hacker @greentheonly stated that the company’s vehicles already had the source codes for a pay-as-you-go subscription model. The Tesla hacker suggested then that Tesla would likely release such a feature by the end of the year — something that Elon Musk also suggested in the first-quarter earnings call. “I think we will offer Full Self-Driving as a subscription service, but it will be probably towards the end of this year,” Musk stated.
While the signs for an upcoming FSD subscription option seem to be getting more and more prominent as the year approaches its final quarter, the details for such a feature are still quite slim. Pricing for FSD subscriptions, for example, have not been teased by Elon Musk yet, though he has stated on Twitter that purchasing the suite upfront would be more worth it in the long term. References to the feature in the vehicles’ source code, and now in the Tesla mobile app, also listed no references to pricing.
The idea of FSD subscriptions could prove quite popular among electric car owners, especially since it would allow budget-conscious customers to make the most out of the company’s driver-assist and self-driving systems without committing to the features’ full price. The current price of the Full Self-Driving suite is no joke, after all, being listed at $8,000 on top of a vehicle’s cost. By offering subscriptions to features like Navigate on Autopilot with automatic lane changes, owners could gain access to advanced functions only as they are needed.
Elon Musk, for his part, has explained that ultimately, he still believes that purchasing the Full Self-Driving suite outright provides the most value to customers, as it is an investment that would pay off in the future. “I should say, it will still make sense to buy FSD as an option as in our view, buying FSD is an investment in the future. And we are confident that it is an investment that will pay off to the consumer – to the benefit of the consumer.” Musk said.
