The Boring Company files permit to extend tunnel project in Los Angeles
Elon Musk’s The Boring company has filed a permit with Los Angeles to extend its tunnel project within city limits. A spokesperson for the Bureau of Engineering, Mary Nemick, confirmed the filing made by Musk’s tunnel digging venture though no further details were provided.
The Tesla and SpaceX CEO previously revealed plans to build an underground tunnel beginning near LAX airport and continue along the westside of Los Angeles, into the San Fernando valley. “First route will go roughly parallel to the 405 from LAX to 101, with on/offramps every mile or so. It will work like a fast freeway, where electric skates carrying vehicles and people on pods on the main artery travel at up to 150mph, and the skates switch to side tunnels to exit and enter.” said Musk.
Los Angeles Mayor Eric Garcetti, who’s historically been a big proponent of Musk and his projects, took to Twitter on Wednesday to welcome The Boring Company’s forward-thinking vision for the city’s transportation system. “Los Angeles has always been a place where innovators come to build new ideas that can change how we live our lives,” said Garcetti. “We look forward to continuing our conversations about this new transportation technology, and exploring the ways that it can help us build a better future for our city.”
If approved, the newly filed permit will allow Boring Co. to dig beyond the existing 2-mile test tunnel that’s currently being constructed beneath 120th street near SpaceX’s headquarters in Hawthorne, CA.
Hawthorne Mayor Alex Vargas said in August, after The Boring Company won city council approval for its tunneling project, “The city of Hawthorne is excited to see the rapid progress at which the tunnel is being completed, we are looking forward to seeing Elon Musk begin testing his system and making subterranean travel a reality here in our city.”

The company has been testing a prototype of an electric skate that will be used to transport vehicles at high speeds within a 13.5 foot diameter tunnel that’s located 44 feet below ground. According to documents submitted to the city council, “The test tunnel project would involve SpaceX engineers repeatedly testing personal vehicle types suitable for placement on the skates; refinement of the design and technology; and general data collection on performance, durability, and application,”
As The Boring Company awaits approval to extend its tunneling project into the westside of Los Angeles, Musk and team will continue to iterate on streamlining the process for tunnel building. Unlike traditional underground tunnels for passenger vehicles, Boring Co.’s tunnels will be smaller and able to maintain a vacuum in order to support Hyperloop transportation. Reducing the tunnel diameter by 50% will also reduce the cross sectional area of the tunnel by a factor of four. Musk noted in his speech at TED2017 that having a smaller tunnel just large enough for a vehicle will cut 75% of the time associated with digging, thereby introducing a significant cost savings. The Boring Company’s tunnel boring machine will also look to install tunnel walls continuously while it digs, thus eliminating the need to pause operations and speeding up the process entirely.
In addition to its project in California, the company received approval by Maryland officials to dig a 10.1-mile tunnel that aims to connect Baltimore with Washington, DC. Maryland Governor Larry Hogan said in a Facebook post on October 19, “Incredibly excited to announce our administration’s support for The Boring Company to bring rapid electric transportation technology to Maryland, connecting Baltimore City and Washington D.C.”

Elon Musk’s xAI bets $20B on Mississippi with 2GW AI data center project
The project is expected to create hundreds of permanent jobs, dramatically expand xAI’s computing capacity, and further cement the Mid-South as a growing hub for AI infrastructure.
Elon Musk’s xAI plans to pour more than $20 billion into a massive new data center campus in Southaven, Mississippi, marking the largest single economic development project in the state’s history.
The project is expected to create hundreds of permanent jobs, dramatically expand xAI’s computing capacity, and further cement the Mid-South as a growing hub for AI infrastructure.
xAI goes MACROHARDRR in Mississippi
xAI has acquired and is retrofitting an existing facility in Southaven to serve as a new data center, which will be known as “MACROHARDRR.” The site sits near a recently acquired power plant and close to one of xAI’s existing data centers in Tennessee, creating a regional cluster designed to support large-scale AI training and inference.
Once completed, the Southaven facility is expected to push the company’s total computing capacity to nearly 2 GW, placing it among the most powerful AI compute installations globally. The data center is scheduled to begin operations in February 2026.
Gov. Tate Reeves shared his optimism about the project in a press release. “This record-shattering $20 billion investment is an amazing start to what is sure to be another incredible year for economic development in Mississippi. Today, Elon Musk is bringing xAI to DeSoto County, a project that will transform the region and bring amazing opportunities to its residents for generations. This is the largest economic development project in Mississippi’s history,” he said.
xAI’s broader AI ambitions
To secure the investment, the Mississippi Development Authority approved xAI for its Data Center Incentive program, which provides sales and use tax exemptions on eligible computing hardware and software. The City of Southaven and DeSoto County are also supporting the project through fee-in-lieu agreements aimed at accelerating development timelines and reducing upfront costs.
Founded in 2023 by Elon Musk, xAI develops advanced artificial intelligence systems focused on large-scale reasoning and generative applications. Its flagship product, Grok, is integrated with the social media platform X, alongside a growing suite of APIs for image generation, voice, and autonomous agents, including offerings tailored for government use.
Elon Musk highlighted xAi’s growth and momentum in a comment about the matter. “xAI is scaling at an immeasurable pace — we are building our third massive data center in the greater Memphis area. MACROHARDRR pushes our Colossus training compute to ~2GW – by far the most powerful AI system on Earth. This is insane execution speed by xAI and the state of Mississippi. We are grateful to Governor Reeves for his support of building xAI at warp speed,” Musk said.
Tesla’s Head of AI, Ashok Elluswamy, says that something that was expected with version 14.3 of the company’s Full Self-Driving platform has already partially shipped with the current build of version 14.2.
Tesla and CEO Elon Musk have teased on several occasions that reasoning will be a big piece of future Full Self-Driving builds, helping bring forth the “sentient” narrative that the company has pushed for these more advanced FSD versions.
Back in October on the Q3 Earnings Call, Musk said:
“With reasoning, it’s literally going to think about which parking spot to pick. It’ll drop you off at the entrance of the store, then go find a parking spot. It’s going to spot empty spots much better than a human. It’s going to use reasoning to solve things.”
Musk said in the same month:
“By v14.3, your car will feel like it is sentient.”
Amazingly, Tesla Full Self-Driving v14.2.2.2, which is the most recent iteration released, is very close to this sentient feeling. However, there are more things that need to be improved, and logic appears to be in the future plans to help with decision-making in general, alongside other refinements and features.
On Thursday evening, Elluswamy revealed that some of the reasoning features have already been rolled out, confirming that it has been added to navigation route changes during construction, as well as with parking options.
He added that “more and more reasoning will ship in Q1.”

Interestingly, parking improvements were hinted at being added in the initial rollout of v14.2 several months ago. These had not rolled out to vehicles quite yet, as they were listed under the future improvements portion of the release notes, but it appears things have already started to make their way to cars in a limited fashion.
Tesla Full Self-Driving v14.2 – Full Review, the Good and the Bad
As reasoning is more involved in more of the Full Self-Driving suite, it is likely we will see cars make better decisions in terms of routing and navigation, which is a big complaint of many owners (including me).
Additionally, the operation as a whole should be smoother and more comfortable to owners, which is hard to believe considering how good it is already. Nevertheless, there are absolutely improvements that need to be made before Tesla can introduce completely unsupervised FSD.

Tesla’s Elon Musk: 10 billion miles needed for safe Unsupervised FSD
As per the CEO, roughly 10 billion miles of training data are required due to reality’s “super long tail of complexity.”
Tesla CEO Elon Musk has provided an updated estimate for the training data needed to achieve truly safe unsupervised Full Self-Driving (FSD).
As per the CEO, roughly 10 billion miles of training data are required due to reality’s “super long tail of complexity.”
10 billion miles of training data
Musk comment came as a reply to Apple and Rivian alum Paul Beisel, who posted an analysis on X about the gap between tech demonstrations and real-world products. In his post, Beisel highlighted Tesla’s data-driven lead in autonomy, and he also argued that it would not be easy for rivals to become a legitimate competitor to FSD quickly.
“The notion that someone can ‘catch up’ to this problem primarily through simulation and limited on-road exposure strikes me as deeply naive. This is not a demo problem. It is a scale, data, and iteration problem— and Tesla is already far, far down that road while others are just getting started,” Beisel wrote.
Musk responded to Beisel’s post, stating that “Roughly 10 billion miles of training data is needed to achieve safe unsupervised self-driving. Reality has a super long tail of complexity.” This is quite interesting considering that in his Master Plan Part Deux, Elon Musk estimated that worldwide regulatory approval for autonomous driving would require around 6 billion miles.
FSD’s total training miles
As 2025 came to a close, Tesla community members observed that FSD was already nearing 7 billion miles driven, with over 2.5 billion miles being from inner city roads. The 7-billion-mile mark was passed just a few days later. This suggests that Tesla is likely the company today with the most training data for its autonomous driving program.
The difficulties of achieving autonomy were referenced by Elon Musk recently, when he commented on Nvidia’s Alpamayo program. As per Musk, “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.” These sentiments were echoed by Tesla VP for AI software Ashok Elluswamy, who also noted on X that “the long tail is sooo long, that most people can’t grasp it.”
