Tesla Autopilot director confirms High Fidelity Park Assist coming for cars with ultrasonic sensors
Arguably the most exciting part of Tesla’s 2023 Holiday Update is the addition of High Fidelity Park Assist. The feature, which allows drivers to see a 3D reconstruction of their vehicles’ surroundings while parking, has long been requested by electric vehicle owners, especially considering the popularity of 360-degree cameras in mainstream vehicles.
So far, however, High Fidelity Park Assist is only available to Tesla’s vehicles that exclusively use Tesla Vision. This means that owners who have cars that are equipped with ultrasonic sensors are yet to receive the function. Fortunately, it appears that plans are underway to release High Fidelity Park Assist to Teslas that are equipped with the company’s older sensor suite.
High-fidelity park assist is shipping this weekend to Tesla customers without ultrasonic sensors as part of the holiday release!pic.twitter.com/MEHL6w003r— Ashok Elluswamy (@aelluswamy) December 17, 2023
This was confirmed by Tesla Autopilot Director Ashok Elluswamy in a recent post on X, the social media platform formerly known as Twitter. While commenting on a video of High Fidelity Park Assist in action, the executive was asked if the feature would also make it to Tesla’s greater fleet. Elluswamy responded in the affirmative, noting that the feature should “eventually go to cars that have ultrasonic sensors as well.”
Elluswamy also provided a pretty comprehensive explanation of the technology behind High Fidelity Park Assist.
“High-fidelity park assist is shipping this weekend to Tesla customers without ultrasonic sensors as part of the holiday release! This replaces the 2D obstacle band that customers had with a high-resolution 3D reconstruction of the Tesla’s surroundings. This is an extension of our Occupancy Network, with much higher resolution to help with tight parking maneuvers.

“The obstacles are modeled as a continuous distance field. This allows us to represent arbitrary shapes in a smooth and computationally efficient way. The vehicles you see are not some fixed meshes, but the network’s real-time prediction of the shape. In addition to obstacles, we also predict painted lines on the ground, also in 3D. Together, these help perform the full parking maneuver just by looking at this one screen.
“This is the v1 release of this technology, and will have follow up releases that have even better geometric consistency with the cameras, better persistence of occluded obstacles, etc. For now, enjoy parking and happy holidays!!” the Tesla Director wrote.
While the confirmation that High Fidelity Park Assist is coming to Teslas with ultrasonic sensors is welcome news, owners of Teslas that have ultrasonic sensors would probably be wise to exercise some patience. The Autopilot Director, after all, did not provide a target timeframe for the feature’s expanded release, only stating that High Fidelity Park Assist would “eventually” get released to Teslas with ultrasonic sensors as well.

Nvidia CEO Jensen Huang explains difference between Tesla FSD and Alpamayo
“Tesla’s FSD stack is completely world-class,” the Nvidia CEO said.
NVIDIA CEO Jensen Huang has offered high praise for Tesla’s Full Self-Driving (FSD) system during a Q&A at CES 2026, calling it “world-class” and “state-of-the-art” in design, training, and performance.
More importantly, he also shared some insights about the key differences between FSD and Nvidia’s recently announced Alpamayo system.
Jensen Huang’s praise for Tesla FSD
Nvidia made headlines at CES following its announcement of Alpamayo, which uses artificial intelligence to accelerate the development of autonomous driving solutions. Due to its focus on AI, many started speculating that Alpamayo would be a direct rival to FSD. This was somewhat addressed by Elon Musk, who predicted that “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.”
During his Q&A, Nvidia CEO Jensen Huang was asked about the difference between FSD and Alpamayo. His response was extensive:
“Tesla’s FSD stack is completely world-class. They’ve been working on it for quite some time. It’s world-class not only in the number of miles it’s accumulated, but in the way it’s designed, the way they do training, data collection, curation, synthetic data generation, and all of their simulation technologies.
“Of course, the latest generation is end-to-end Full Self-Driving—meaning it’s one large model trained end to end. And so… Elon’s AD system is, in every way, 100% state-of-the-art. I’m really quite impressed by the technology. I have it, and I drive it in our house, and it works incredibly well,” the Nvidia CEO said.
Nvidia’s platform approach vs Tesla’s integration
Huang also stated that Nvidia’s Alpamayo system was built around a fundamentally different philosophy from Tesla’s. Rather than developing self-driving cars itself, Nvidia supplies the full autonomous technology stack for other companies to use.
“Nvidia doesn’t build self-driving cars. We build the full stack so others can,” Huang said, explaining that Nvidia provides separate systems for training, simulation, and in-vehicle computing, all supported by shared software.
He added that customers can adopt as much or as little of the platform as they need, noting that Nvidia works across the industry, including with Tesla on training systems and companies like Waymo, XPeng, and Nuro on vehicle computing.
“So our system is really quite pervasive because we’re a technology platform provider. That’s the primary difference. There’s no question in our mind that, of the billion cars on the road today, in another 10 years’ time, hundreds of millions of them will have great autonomous capability. This is likely one of the largest, fastest-growing technology industries over the next decade.”
He also emphasized Nvidia’s open approach, saying the company open-sources its models and helps partners train their own systems. “We’re not a self-driving car company. We’re enabling the autonomous industry,” Huang said.

Elon Musk confirms xAI’s purchase of five 380 MW natural gas turbines
The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.
xAI, Elon Musk’s artificial intelligence startup, has purchased five additional 380 MW natural gas turbines from South Korea’s Doosan Enerbility to power its growing supercomputer clusters.
The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.
xAI’s turbine deal details
News of xAI’s new turbines was shared on social media platform X, with user @SemiAnalysis_ stating that the turbines were produced by South Korea’s Doosan Enerbility. As noted in an Asian Business Daily report, Doosan Enerbility announced last October that it signed a contract to supply two 380 MW gas turbines for a major U.S. tech company. Doosan later noted in December that it secured an order for three more 380 MW gas turbines.
As per the X user, the gas turbines would power an additional 600,000+ GB200 NVL72 equivalent size cluster. This should make xAI’s facilities among the largest in the world. In a reply, Elon Musk confirmed that xAI did purchase the turbines. “True,” Musk wrote in a post on X.
xAI’s ambitions
Recent reports have indicated that xAI closed an upsized $20 billion Series E funding round, exceeding the initial $15 billion target to fuel rapid infrastructure scaling and AI product development. The funding, as per the AI startup, “will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products.”
The company also teased the rollout of its upcoming frontier AI model. “Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote in a post on its website.
