Tesla has officially removed the Sonic game from its vehicles in 2022’s holiday update.
The Austin-based automotive company added Sonic the Hedgehog with its 2021 holiday update, so the game was only available to owners for one year and required a USB controller to play.
In early 2022, Tesla added Sonic to vehicles that did not have data-capable USB ports in the front (only in the glovebox). “A game controller plugged into the glovebox USB port is required,” reads the version 2022.28.1 release notes.
Sonic the Hedgehog in a Tesla
Sonic the Hedgehog is a platform video game that was released in 1991 by Sega for their Genesis gaming system. Players control a blue hedgehog, named Sonic, to run at fast speeds on a mission to overtake Dr. Robotnik, a mad scientist who has locked away animals inside robot bodies while chasing after the Chaos Emeralds.
It’s currently unclear as to why Tesla has removed the game or if it’ll be back. The game may be gone due to a bug or license expiration. Sega first announced that Sonic the Hedgehog was coming to Teslas in December 2021.
With the addition of Steam to some of its vehicles, Tesla may be transitioning away from adding games itself. Instead, they’ll focus efforts on ensuring Steam is running as smoothly as possible on its operating system so users can enjoy the vast catalog of games within Steam's library, including a plethora of Sonic games.
If you have a Model S or Model X with Steam integration, Sonic the Hedgehog 1 is available in the Sonic Origins game; a paid game available on Steam.
Will Tesla add Sonic the Hedgehog back to its own gaming library? It's anyone's guess at this point, but the removal of Sonic was not mentioned in the 2022 holiday update release notes, so it could have been accidental. Tesla is the only one that knows how often these games are played and whether it's worth their time and money adding them. It may make more sense for Tesla to focus on building out other features for owners to use and enjoy.

Tesla’s Optimus humanoid robot is back in the spotlight, and this time it's showing off some impressive new footwork. In a pair of videos shared on X this week, Optimus demonstrated a surprising level of agility and coordination while dancing. The first demonstration had a precautionary safety cable, but the second demo was impressive without support.
Tesla has been making some astounding advances in Optimus’ unique FSD model, particularly through simulation and reinforcement learning. Optimus has come a long way since tripping over its own feet.
This first glimpse showed Optimus performing a simple series of dance-like movements. While there was a safety cable visible, indicating the relatively early nature of the test, the fluidity of the movements was noteworthy. Check out those feet—maintaining balance on two legs may be easy for humans, but it’s much harder for a robot as it shifts its center of gravity.
Milan Kovac, a member of the Optimus AI team, provided some additional context on this initial video. He mentioned that more was coming shortly, and the team has been hard at work. What’s key here is that he emphasized that the routine was entirely trained in simulation with reinforcement learning. He also mentioned that there are many optimizations and fixes already put in place for the sim-to-real training code. Finally, regarding the cable, he mentioned it's there in case of a fall and that it is not actually holding Optimus up directly.
Dance Baby, Dance
True to Kovac’s promise, the Tesla Optimus X account followed up with a second, more impressive video, declaring that it was just “getting warmed up.”
This time, Optimus engaged in a far more dynamic EDM-style dance, and crucially, without a safety cable or restraint. Optimus put on a good show of its balance, quicker movements, and an even greater range of dynamic motion, all untethered.
Murtaza Dalal, another Optimus AI team member, commented on this cable-free performance, stating, "As promised, the team is crazy fast :)" He pointed to the core methodology enabling such rapid progress: "Sim2real RL is the key to getting next level agile, dynamic motions. It’s also the key to precision and robustness."
Sim-to-Real Learning
The recurring theme from the Optimus team is the power of sim-to-real transfer using reinforcement learning. This approach involves training the AI model extensively in a simulated virtual environment, where it can learn complex behaviors (like walking, balancing, and now dancing) through trial and error at an accelerated pace. The best part is that it can all be done without risking damage to the physical hardware and done across multiple nodes of Tesla hardware. Imagine thousands of Optimus bots learning to dance all at once - except virtually.
Once the AI masters these skills in the simulation, the challenge lies in transferring that learning effectively to the real-world robot - which is the sim-to-real step.
These latest dance demonstrations suggest Tesla is making some fairly substantial strides in bridging that gap, allowing Optimus to translate simulated learning into real-world physical competence.
Rapid Development
While dancing may seem like a novelty, it serves as a compelling visual demonstration of Optimus’ advanced capabilities in balance, coordination, and dynamic movement - all essential for performing useful tasks in real-world environments. This progress builds on previous milestones, like Optimus learning to walk.
The "crazy fast" development pace lauded by Dalal indicates that Tesla is treating Optimus with the same iterative intensity it applies to its vehicles and FSD software. Each new demonstration, from sorting objects to walking and now dancing, offers a glimpse into a future where humanoid robots could play an important role in manufacturing, logistics, and eventually daily life.
The ability to quickly iterate and improve in simulation and then successfully deploy those improvements to the physical robot is crucial. While Optimus might not be ready for household chores just yet, its new dance moves are a clear sign that FSD is learning and evolving at an impressive rate.
A recent sighting at Giga Texas by drone operator and detail hound Joe Tegtmeyer has really caught our eye. A red Model Y was driving within the factory premises with its front and rear sections heavily camouflaged in Tesla’s standard black coverings. To top it off, there wasn’t just one, but two vehicles.
Tesla usually conceals vehicles when it has something to hide or test, and this timing suggests to us that a new variant of the world’s best-selling SUV is on its way. This leads us to two theories - a refreshed Model Y Performance or the anticipated, more affordable E41 Model Y.
Caught something interesting today … two heavily camouflaged cars driving on the W side of Giga Texas. Several viewers noted this in my short video on the autonomous drive.

The front fascia, headlights, and hood are almost entirely obscured, with similar coverings applied to the rear, hiding the taillight design and bumper. This is a classic practice to keep new design elements under wraps before an official unveiling, and this is exactly what we saw with the Model 3 Highland and Model Y Juniper projects. The rest of the vehicle, including the central body and roofline, appear fairly consistent with the current Model Y.
Refreshed Model Y Performance?
One compelling possibility is that Tesla is preparing for the launch of the refreshed Model Y Performance. This speculation gains traction when we look at the launch of the refreshed Model 3 Performance. The Performance variant launched several months after the Long Range AWD and RWD variants and came with a bespoke front fascia. That fascia included air ducts for improved aerodynamics and brake cooling, helping to differentiate it both visually and by performance from other refreshed Model 3s.
It stands to reason that Tesla is preparing to launch the refreshed Model Y Performance. The extensive covering on the front fascia could be hiding a more aggressive, aerodynamically optimized bumper and air ducts to match the Model 3 Performance.
More Affordable Model Y?
Alternatively, this mystery vehicle could be the prototype of the previously discussed affordable variant of the Model Y, known as E41. Tesla has been working on further cost reductions for its highest volume vehicle, which includes cost-cutting components and features, as well as working on manufacturing efficiencies.
Tesla is focusing on making its existing models, like the Model Y, more affordable. In this case, the camouflage might be concealing simplified exterior features designed to help reduce production costs. This could include a revised front-end design, along with different headlights or taillight assemblies. Tesla could even forgo the distinctive front lightbar, as well as the afterburner-style rear lightbar, if it contributes to worthwhile savings.
This would be a step beyond the recently introduced Model Y Long Range RWD, which improves the vehicle’s range and lower the price by $4,000.
For now, the identity of this camouflaged Model Y remains a mystery. The fact that it is out and about at Giga Texas suggests that whatever changes Tesla has incorporated are significant enough to warrant covering up the front and rear of the vehicle.
