Tesla AI Day 2021 Event Recap

By Henry Farkas

Tesla AI day was last night and most of the event was an in-depth look at how Tesla is solving FSD and all the problems their solving and methods they're using. It definitely wasn't aimed at at the casual consumer.

Tesla AI Day 2021

There was some interesting video where they showed how the integration of all the cameras could predict where other traffic is located, and do it better than the combination of a few cameras combined with radar. We had to take their word for it that the camera integration did a better job. It did look that way on the computer views. Elon also pointed out that they use the Autopilot software not only to drive the car but to predict where the other cars on the road are likely to be in the next few seconds.

Later in the show, things got more interesting. They brought out a person dressed like a robot who danced around a bit. Elon came out again and showed a plan for a human-shaped Tesla robot. He admitted that the one that had danced around the stage wasn't the actual robot, but said that's what the Tesla robot would look like. The purpose of the robot is to perform chores that humans might find boring, repetitive, or dangerous.

Elon mentioned that Teslas are basically semi-sentient robots on wheels. He said that the human-shaped Tesla bot would come out next year. The robots will be friendly and will be able to navigate a world built for humans. They will be five feet eight inches tall and weigh 125 pounds, The face will be a computer screen. The hands will look like human hands and have five fingers. The Tesla bot will be able to walk at five miles/hour. That's faster than normal human walking speed, but most people can run faster than that.

Elon casually mentioned that most people could run away from it and most likely overpower it. He hoped it wouldn't be necessary, but, he said, “You never know.”

So then, he said that the robots would be able to shop for people, do chores around the house, and do repetitive jobs in the workplace. He admitted that having robots available to do jobs in the workplace would be a problem unless there was a universal basic income. That got a cheer from the audience. So I guess there were lots of Andrew Yang fans in the audience.

Then the question period started. The first question was asked of Musk, did he plan to make any of his software open-source? He said that creating it cost too much to just give it away, but he'd be willing to license it to other car companies.

Another interesting question was about whether audible cues would be incorporated into the FSD computer. Elon admitted that it would be important for a fully autonomous car to hear sirens from emergency vehicles, and he said that if someone was yelling at the car from the outside, a fully autonomous car should be able to understand what was being said. It'll be interesting how Tesla plans to tackle this problem for vehicles without external microphones.

Later, someone asked if FSD would work in other countries. Elon said that they were focusing first on the US, but the point was made that driving is very similar in other countries. Elon mentioned that they use training data from fifty countries and that the prime directive of FSD is, “Don't crash.” And that's true in every country. He says that right now, the car is pretty good at not crashing. Clearly, pretty good is not good enough since the drivers still need to pay attention, but the FSD is programmed to not crash into anything on the highway even if it's something it doesn't recognize like a UFO that just crashed on the highway.

I have to mention, here, an experience I had while FSD was engaged. I was driving along a road at night, and I saw a rock in the middle of the road. It was clear that the car didn't see it, and I had to quickly steer around it because it was too late to stop by the time the rock appeared in my headlights. Now I don't have the beta version of FSD, but it's clear Tesla still has some work to do here.

Later, someone asked what will happen with FSD once hardware 4 gets into production. Elon said that hardware 3 will be able to drive much better than any human driver once the software is finished. He says that hardware 4 will come out with the Cybertruck, and it will be able to drive better than hardware 3, but that doesn't mean that hardware 3 is unable to drive. He pointed out that not every regular human driver is the best driver on the road, but that doesn't mean that the regular driver isn't allowed to drive.

An amusing question got asked about whether the car could be spoofed by a picture. Elon suggested that he doesn't see many paintings of tunnels on rock walls as in Wiley E. Coyote cartoons. He mentioned that he has a T-shirt with a stop sign on the front. He says that if someone flashes a Tesla with such a T-shirt, the car will stop, but that Tesla will soon train edge cases like these and the car will learn what is a real stop sign versus a fake one.

Toward the end, someone asked whether we should worry that AI will have its own priorities that might be different from the priorities of the owners of the artificially intelligent robots. Elon said that right now, we're not anywhere near the kind of self-aware super-intelligent robots that people worry about. A car may be able to drive better than most humans. A robot may be able to do boring, repetitive or dangerous activities. That doesn't mean that cars and robots might rise up and rebel against humans. He's going to program his cars and his robots to be “Unequivocally good.”

Elon's final comment about cars was that eventually, cars will drive themselves just like elevators now drive themselves. You get in an elevator, press a button, and it takes you where you want to go. There aren't elevator operators anymore. Eventually, self-driving cars will be the norm. He says that there will still be a few gasoline cars and cars that need to be driven by a human being, just like now, there are still a few horses. But non-self-driving cars will be rare.

Tesla Semi Keynote: New Features, 46 Charging Sites, Upgraded Battery & More [VIDEO]

By Karan Singh
Out of Spec BITS/YouTube

Tesla’s Dan W Priestley attended the Advanced Clean Transportation (ACT) Expo in Anaheim, California, and provided an update on Tesla’s Semi truck program. The presentation covered several key developments on the status of Tesla’s Nevada Semi Factory, refinements to the Semi, and Tesla’s plans for charging and ramping production through 2026.

Let’s dig in and take a look at everything that was captured by the Out of Spec team at ACT Expo. The original video is embedded below if you’d like to watch it.

Semi Factory & Production Ramp

Priestley reaffirmed the timelines mentioned during Tesla’s Q4 2024 Earnings Call that Tesla will scale Semi production in 2026. To achieve this, Tesla has been actively building and expanding the Gigafactory Nevada site, specifically to support the production of the Tesla Semi. The dedicated Semi facility will have a targeted annual capacity of 50,000 Semi trucks.

Following the beginning of production, Tesla will utilize the initial trucks to integrate into its own logistics operations. This will serve as both a final real-world testing ground as well as an opportunity for Tesla to gather data internally. Tesla plans to begin subsequent customer deliveries throughout 2026 as the ramp-up continues.

Reuters also reported that Tesla is hiring over 1,000 new employees at the Semi Factory to begin the rapid ramping of the program.

Semi has already amassed 7.9 million miles with Tesla’s current testing and operational fleets, providing some real-world data and testing. Feedback for the truck has been exceptionally successful, with many drivers praising the Semi’s performance and comfort.

New Tesla Semi Features

Of course, it wouldn’t be a Tesla keynote without showing off some new things. The Semi will be available in 500-mile and 300-mile range configurations, now featuring updated mirror designs and a drop-down glass section to improve visibility and allow easier interaction with external elements—such as control panels at ports, for example.

New Electric Power Take-Off (e-PTO)

The Tesla Semi will also feature a new capability called Electric Power Take-Off, or e-PTO system. Similar to the PTO systems found on other vehicles, this will allow the Semi’s high-voltage battery to power auxiliary equipment at variable voltages. That includes being able to power things like climate-controlled reefer trailers, potentially replacing the noisy and polluting diesel generators traditionally used for this purpose.

Charging and Batteries

Tesla is also working on an updated battery pack design for the final production design of the Semi. This new pack is designed to be more cost-effective to manufacture. The battery pack itself is slightly smaller than before, but the truck maintains the same level of range through efficiencies. Dan also confirmed during his keynote that the battery cells for the Semi will be sourced domestically inside the United States, helping to alleviate potential burdens due to tariffs.

On the charging front, Tesla is using MCS - the Megawatt Charging System - capable of 1.2MW - and designed specifically for Semi. The system uses the same V4 charging hardware found at Supercharger sites but focuses on that larger power output. Alongside a smaller physical footprint, Tesla will be able to configure these V4 cabinets for either dedicated Semi charging or for shared power scenarios with regular Superchargers. Tesla is also working on an integrated overnight charging product, but Tesla isn’t ready to talk about it yet.

46 Semi Charger Sites Coming

Finally, Tesla has made substantial investments in a public charging network for the Semi. There are currently 46 sites in progress throughout the United States, and plans for significant expansion throughout 2026 and 2027. These sites are strategically located alongside major truck routes and within industrial areas to support long-haul and regional operations. Tesla is aiming to offer the lowest possible energy costs to operators to help incentivize adoption.

This was one of the best updates to the Tesla Semi we’ve received since its initial unveiling. It seems that the Semi will receive a big portion of Tesla’s attention in 2026, while Robotaxi and FSD Unsupervised take the stage this year.

The Tesla Semi has the potential to transform transportation even more dramatically than EVs already have, serving as a testament to Tesla’s mission to electrify the world.

Tesla’s B-Pillar Sentry Mode Recording Requires HW4, Not Just Ryzen — Breakdown of Spring Update Requirements

By Karan Singh
Not a Tesla App

Sentry Mode is an invaluable tool for owners - capable of keeping the vehicle safe and secure even when you’re not around. This is especially true in recent times, with the misguided and unfortunate incidents surrounding Tesla ownership, including damage to Tesla vehicles, showrooms, and Superchargers.

B-pillar Camera Recording and Dashcam Viewer

With the 2025 Spring Update on 2025.14, Tesla is expanding Sentry Mode’s functionality for certain vehicles with some much-needed changes. Sentry Mode and Dashcam can now record footage from the vehicle’s B-pillar cameras. These cameras are located on the side pillars of the vehicle, between the front and rear doors.

This adds two crucially needed viewpoints, making Tesla’s Sentry Mode a truly 360-degree security system. These cameras also provide the best angles for capturing license plates when parked, so they will be greatly appreciated by owners in the event of an incident.

These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view. It also allows users to jump back or forward in the video in 15-second increments.

However, to the disappointment of many owners, not all vehicles are receiving these updates due to the additional processing power needed.

Limited to Hardware 4 Vehicles, Ryzen Isn’t Enough

We have confirmed that Tesla is only adding the additional camera recording and improved Dashcam Viewer on hardware 4 (HW4 / AI4) vehicles. The newer hardware presumably has the additional processing power and bandwidth needed to handle recording and saving the two additional video streams during Sentry Mode and Dashcam.

For the time being, owners of HW3 vehicles are not receiving this feature. This includes all vehicles with HW3, even those with AMD Ryzen infotainment systems. If you’re not sure whether your vehicle has HW3 or HW4, you can refer to our FSD hardware guide.

While there’s no doubt that recording two additional camera streams would be more computationally intensive, we hope that Tesla adds the improved Dashcam Viewer to HW3 vehicles in a future update.

Cybertruck Also Missing Improved Sentry Mode

Surprisingly, and most confusing for many - is the fact that the Cybertruck is also not receiving the improved Dashcam Viewer and B-pillar camera recording with this update. This struck us as odd, especially since the Cybertruck is currently the only vehicle with the improved, more efficient version of Sentry Mode.

Every Cybertruck is equipped with HW4 and AMD Ryzen infotainment units, so this clearly isn’t a hardware restriction. It’s possible the more efficient Sentry Mode is playing a role here due to the infrastructure changes. However, we expect Tesla to address this in a future update and eventually release these features for the Cybertruck as well.

Given the Cybertruck’s high visibility and its status as a frequent target for both positive and negative attention, many owners hoped that the Cybertruck would be one of the vehicles to receive this feature.

Adaptive Headlights

Tesla finally started rolling out its adaptive headlights in North America. While the new Model Y already came with the feature when it was released last month, other vehicles with matrix headlights are now receiving the feature in the Spring Update.

All vehicles with matrix headlights are receiving this feature, which includes the new and old Model 3, first-gen Model Y, and the new Model S and Model X.

If you’re not sure if your vehicle includes matrix headlights, check out our guide. What’s interesting here is that older vehicles that were retrofitted with matrix headlights due to an accident or user replacement are also receiving the adaptive headlights feature.

Legacy Model S & Model X

As with most updates, the older legacy Model S and Model X are not receiving all the features included in this update. Unfortunately, some of the features, which include the Blind Spot Camera on the instrument cluster, Save Trunk Height Based on Location and Keep Accessory Power On are limited to the new Model S and X.

Legacy S and X models will receive the Alternative Trip Plans feature, Avoid Highways (Requires Intel MCU) and the Keyboard Languages feature.

These vehicles are also receiving all the features in the Minor Updates section except for the visualization showing how far the door is opened, which is exclusive to the Cybertruck. These additions include improved music search results, contact photos in the phone app, automatic connecting to hotspots, the ability to show third-party chargers, view Supercharger amenities, and various improvements to music services.

While many users will be disappointed not to receive the B-pillar camera recording and Dashcam Viewer improvements, it’s important to remember that Tesla typically does a great job at bringing features to older vehicles, at least with the Model 3 and Model Y. If a feature isn’t added, it’s usually due to a hardware limitation.
