NYC subway closure canceled, Elon Musk’s Boring Company tapped for ideas to improve other systems
The Governor of New York State, Andrew Cuomo, announced on Thursday evening that the current plan to shut down the 225,000 commuter-strong L-train tunnel in the New York City public transportation system for a 15-month-long repair process will no longer be necessary due to a plan implementing new reconstruction techniques. After consulting with a panel of expert engineers from Columbia and Cornell Universities, a new design was proposed to be used in the tunnel which would streamline the repair process and require closures during nights and weekends with partial train tunnel service still available. When asked in a conference call Friday whether other innovators such as Elon Musk of Tesla and The Boring Company were consulted, the governor said Musk had not advised on this specific issue, but was consulted on improvements to the subway’s signaling system. The Metropolitan Transport Authority (MTA), New York’s transportation network, accepted the Governor’s panel recommendations following the announcement.
The L train tunnel under the East River connecting Brooklyn and Manhattan in New York, known as the Canarsie Tunnel, was damaged during Hurricane Sandy, the Category 3 major hurricane which affected the entire eastern seaboard of the United States in 2012. Its storm surge hit NYC on October 29, flooding huge portions of the island, including 9 of the 14 underwater tunnels in the city’s transport system. Of these, 6 have already been repaired. According to the MTA, the damage to the Canarsie Tunnel is comparable to tunnel damage experienced on 9/11, underlining the extent of the repairs needed and the reason behind the original required shutdown.

Saltwater flooding in from the East River during Sandy significantly damaged the infrastructure of the 7,100-foot-long tunnel, including tracks, signals, switches, cables, and lighting. The flood waters additionally filled protected cable tube pathways called “duct banks” throughout the tunnel, and once dry, the silt hardened to a cement-like consistency inside them, making it impossible to rip out and restore the damaged components. Canarsie Tunnel also opened in 1924, adding age to the brewing number of problems being amplified by the lingering effects of corrosive saltwater remnants from Sandy.
In 2016, residents were informed the tunnel was possibly going to be shut down for 15 months to address the extensive repairs, causing significant commute challenges for the approximately 225,000 riders depending on the service. The date for service closure was scheduled to begin April 27, 2019, but the impending deadline motivated Governor Cuomo to seek out alternative solutions. “I can’t tell you the number of people in Brooklyn who have looked me right in the eye and said, ‘Are you sure that there is nothing else that can be done and there’s no way you can possibly shorten this?’,” Cuomo stated in a recent press conference announcing the new subway repair plan.

The repair announcement was the end result of a review process Governor Cuomo began on December 14, 2018, wherein he and a consulting team walked through the damaged tunnel to assess the repairs needed first hand. While the plan will take longer than the original project’s timeline – 20 months instead of 15 – the ability to remain open during the repairs is a welcome relief for city residents. The technology that will enable the tunnel to remain open includes wire wrapping along with ultrasound and laser measurement (LIDAR) tools to assess and monitor damage. Engineers from Cornell University’s College of Engineering and Columbia University’s Fu Foundation School of Engineering and Applied Science with expertise in the type of construction involved were the primary sources for the solutions chosen.
Similar to the innovations that came from Musk’s Boring Company tunneling project, the governor has hopes that the unique system planned for the Canarsie Tunnel will inspire other similar repair projects. “This could be a national model because it is a totally different way to reconstruct a tunnel,” Governor Cuomo touted at the press conference. Also, according to the governor, the techniques in the new plan have been implemented in projects in Europe before for bridge repair, but not in tunnel reconstruction. He hopes to bring more out-of-the-box innovations to the city’s transportation as well. In reference to Elon Musk’s companies, he said, “I don’t believe a time where they’re talking about flying cars and you can get into a car and drive 100 miles on the LIE and never touch the steering wheel, that there’s not a better technology that can regulate the trains!”

Tesla plans to resolve its angriest bunch of owners: here’s how
Since the rollout of the AI4 chip in Tesla vehicles, owners with the last generation self-driving chip, known as Hardware 3, have been persistent in their quest for a solution to their issue: they were told their cars were capable of unsupervised Full Self-Driving. It turns out the cars are not.
Tesla has a plan to make Hardware 3 owners whole after CEO Elon Musk admitted that those with that self-driving chip in their cars will not have access to unsupervised Full Self-Driving.
The company’s strategy is so crazy that it is sort of hard to believe.
Since the rollout of the AI4 chip in Tesla vehicles, owners with the last generation self-driving chip, known as Hardware 3, have been persistent in their quest for a solution to their issue: they were told their cars were capable of unsupervised Full Self-Driving. It turns out the cars are not.
Tesla owners with HW3 finally get their answer: https://t.co/CSZTKKkWXx

During the Tesla Q1 earnings call on Wednesday, Musk finally clarified what the company’s plans are for Hardware 3 owners, what they will be offered, and what Tesla will have to do internally to prepare for it.
The answer was somewhat mind-boggling.
Musk said:
“Unfortunately, Hardware 3 — I wish it were otherwise, but Hardware 3 simply does not have the capability to achieve unsupervised FSD. We did think at one point it would have that, but relative to Hardware 4, it has only 1/8 of the memory bandwidth of Hardware 4. And memory bandwidth is one of the key elements needed for unsupervised FSD.”
He continued, stating that HW3 owners would have the opportunity to trade their cars in at a discounted rate in order to get the AI4 chip:
“So for customers that have bought FSD, what we’re offering is essentially a trade-in — like a discounted trade-in for cars that have AI4 hardware, and we’ll also be offering the ability to upgrade the car, to replace the computer. And you also need to replace the cameras, unfortunately, to go to Hardware 4.”
Obviously, Tesla has a lot of people to work with and make this whole thing right. Musk was adamant that HW3 would be capable of FSD, and now that the company has finally admitted that it is not, there are some things that could come of this.
There has been open talk about some sort of class action lawsuit against Tesla. The promises that Tesla made previously could be considered a breach of contract or even false advertising, and that’s according to Grok, Musk’s own AI program.
Musk went on to say that Tesla would likely have to establish new microfactories to effectively and efficiently replace HW3 computers and cameras:
…So to do this efficiently, we’re going to have to set up, like kind of micro factories or small factories in major metropolitan areas in order to do it efficiently. Because if it’s done just at the service center, it is extremely slow to do so and inefficient. So we basically need like many production lines to make the change.”
This is going to be an extremely costly process, especially if Tesla has to buy real estate, properties, and equipment to complete this work. Additionally, there was no wording on pricing, but Musk never said it would be free. It will likely come with some kind of price tag, and HW3 owners, after being left hanging for so long, will have something to say about that.

SpaceX just got pulled into the biggest Weapons Program in U.S. history
SpaceX joins the Golden Dome software group, deepening its role in America’s most expensive defense program.
SpaceX has joined a nine-company group developing the core operating software for the Golden Dome, America’s next-generation missile defense system. According to a Bloomberg report, SpaceX is focused on integrating satellite communications for military operations and is working alongside eight other defense and artificial intelligence companies, including Anduril Industries, Palantir Technologies, and Aalyria Technologies, to build software connecting missile defense capabilities.
The Golden Dome concept dates back to President Trump’s 2024 campaign, and on January 27, 2025, he signed an executive order directing the U.S. Armed Forces to construct the system before the end of his term. The system is planned to employ a constellation of thousands of satellites equipped with interceptors, with data centers in space providing automated control through an AI network.
FCC accepts SpaceX filing for 1 million orbital data center plan
Space Force Gen. Michael Guetlein, director of the Golden Dome initiative, has described the software layer as a “glue layer” that would enable officers to manage and control radars, sensors, and missile batteries across services. The consortium is aiming to test the platform this summer.
Trump selected a design in May 2025 with a $175 billion price tag, expected to be operational by the end of his term in 2029, though the Congressional Budget Office projected the cost could reach $831 billion over two decades.
The Golden Dome role is only the latest in a string of military wins for SpaceX. As Teslarati reported, the U.S. Space Force awarded SpaceX a $178.5 million task order on April 1, 2026 to launch missile tracking satellites for the Space Development Agency, covering two Falcon 9 launches beginning in Q3 2027. That came on top of more than $22 billion in government contracts held by SpaceX as of 2024, per CEO Gwynne Shotwell, spanning NASA resupply missions, classified intelligence satellites through its Starshield program, and military broadband.
The accumulation of defense contracts, now including a seat at the table on the most expensive weapons program in U.S. history, positions SpaceX as the dominant infrastructure provider for American national security in space. With a SpaceX IPO still on the horizon, each new contract adds weight to what is already one of the most consequential companies in aerospace history, raising real questions about how much of America’s defense architecture will depend on a single private operator before it ever trades publicly.

Tesla pulls back the curtain on Cybercab mass production
Tesla’s Cybercab drives itself off the Gigafactory Texas line in a striking new production video.
Tesla has provided a first look from inside a production Cybercab as it drove itself off the assembly line at Gigafactory Texas. The video footage, posted on X, opens on the factory floor with robotic arms and assembly equipment visible through the Cybercab windshield, and follows the car through a branded tunnel marked “Cybercab”, before autonomously navigating itself to a holding lot.
The first Cybercab rolled off the Giga Texas production line on February 17, 2026, with Musk writing on X, “Congratulations to the Tesla team on making the first production Cybercab.” April marked the official shift to volume production. The Giga Texas line is being prepared to produce hundreds of units per week, with 60 units already spotted on the Gigafactory campus earlier this month.

The Cybercab was first revealed publicly at Tesla’s “We, Robot” event in October 2024 at Warner Bros. Studios in Burbank, California, where 20 pre-production units gave attendees rides around the studio lot. Musk said he believed the average operating cost would be around $0.20 per mile, and that buyers would be able to purchase one for under $30,000. The two-seat design is deliberate. Musk noted that 90 percent of miles driven involve one or two people, making a compact two-passenger vehicle the most efficient configuration for a fleet-scale robotaxi. Eliminating rear seats also removes complexity and cost, supporting that sub-$30,000 target.
Tesla’s annual production goal is 2 million Cybercabs per year once several factories reach full design capacity. The Cybercab has no steering wheel, no pedals, and relies entirely on Tesla’s vision-based FSD system. What the video shows is the first evidence of that system working not as a demo, but as a production reality, driving itself off the line and into the world.
