Musk outlines cost-cutting plan for Boring Co: cheaper, faster tunnel digging

Published

One of the large reveals made by Tesla and SpaceX Chief Elon Musk at TED2017 was his plan to create a multi-layer high-speed tunnel infrastructure to support mobility by way of electric skates and Hyperloop tubes.

A key point that he drove home for the underground tunnel network was the integration of the system into cities.

“You have to be able to integrate the entrance and exit of the tunnel seamlessly into the fabric of the city. So, by having an elevator, sort of a car skate that is on an elevator, you can integrate the entrance and exits to the tunnel network just by using 2 parking spaces.”

Musk shared a video demonstrating how skate elevators would be integrated into city streets where they await vehicles looking to be transported through the underground labyrinth of tunnels. The serial tech entrepreneur envisions loading docks wherein vehicles would simply pull into the skate, get lowered into the tunnel network, and be sent along a slot car-like track at speeds of 200 km/h ( 124 mph). The Boring Company’s tunnel network won’t simply alleviate surface congestion, it will completely transform the way we move cars, people and freight, says Musk.

It is worth noting that The Boring Company and Tesla are under control of Musk, while the Hyperloop project has been open sourced, but with support from SpaceX.

Eliminating human drivers allows the skates to move at much faster speeds than human-controlled vehicles. Fixed routes within the tunnel network further improve safety beyond the dynamic nature of  human-determined driving routes. The tunnel network is also infinitely scalable. “You can alleviate any arbitrary level of open congestion with a 3D tunnel network.” and that “There’s no real limit to how many levels of tunnels you can have.”, says Musk from TED2017.

The key barrier to creating tunnels today is the exorbitant cost. The recent 2.5 mile expansion to the Los Angeles subway system came at a cost of nearly $1 billion per mile. Musk and team at the Boring Company hope to cut the cost of tunneling by a significant amount by streamlining the tunneling process and reinventing the machines that help facilitate the digging.

Building Tunnels For Less

First, the team is looking to cut the diameter of the tunnels they dig, moving from the traditional tunnel diameter for passenger vehicles of 26 to 28-feet to a 12-foot standard diameter which would be sufficient for the Tesla skate. On the surface, this might not seem like a lot, but cutting the diameter by 50% cuts the cross sectional area by a factor of four. This is significant as the speed and cost of tunneling is largely driven by the amount of cross sectional area to dig. Being able to cut out 75% of the time associated with digging comes with enormous cost savings.

Second, the team plans to attack head-on the way tunneling machines currently dig. Traditional machines dig, slowly and incrementally, then stop to install reinforcements to support the newly exposed earthen walls. Musk and team are working to install the reinforcements continuously thus eliminating the need to pause operations. This integration is expected to increase the speed of the overall process by as much as 50%.

Finally, the team believes that current digging machines are nowhere near their power and thermal limits, and is looking to ‘jack up the power’ to the digging machines. Doing this, the team hopes to increase the speed by a factor of 4 or 5 on top of the other improvements being suggested by Musk.

Musk also revealed that The Boring Company has a pet snail named Gary who can currently travel at 14 times the speed of existing tunneling machines. While this is more a testament about how slow the boring process is than the amazing speed of Gary, it is a fun target for the team, to be able to build tunnels quicker than Gary can crawl, and continues the comedic spin on the new company.

These tunnels could be kept at or near a vacuum to reduce or eliminate air resistance for all the moving objects within it. Curiously, Musk shared that,

“To withstand the water table, you have to design a wall to be able to withstand 5 or 6 atmospheres. To go to vacuum, you only need to be able to withstand 1 atmosphere.”

It is clear that Musk is very excited about this new Boring Company. He indicated during his sit down at TED2017 that he spends 2-3% of his time on the project, noting that it’s essentially being run as not much more than an intern project with a used boring machine and a few people dedicating partial effort to it.

Tesla has officially begun the wide rollout of Full Self-Driving (Supervised) v14 to the Cybertruck about a month after the company started rolling it out to other vehicles in the fleet.

On Monday, Tesla officially started rolling out v14.1.5 to Cybertruck owners, the first FSD v14 rollout for owners of the all-electric pickup.

Owners have been anxiously waiting for Tesla to begin the wide release of v14 to Cybertruck, as the company said it would refine the suite for the vehicle.

Tesla has finally started rolling out to many owners, who are reporting that their Cybertrucks are downloading Software Update 2025.38.8.5, which contains FSD v14.1.5:

Tesla has to be more cautious with rolling out FSD on the Cybertruck than on other vehicles for a few reasons. Initially, the Cybertruck utilizes an all-wheel steering system that turns differently than the S3XY lineup. This creates a challenge for the Tesla AI team as they have to cater to this specific maneuvering change.

Additionally, the Cybertruck is much larger, and the exterior cameras responsible for seeing the vehicle’s surroundings are placed differently than those of the other vehicles.

This requires additional calibration to ensure safety.

The full release notes for Full Self-Driving v14.1.5 are as follows:

  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, in a Parking Garage, or at the Curbside.
  • Added handling to pull over or yield for emergency vehicles (e.g. police cars, fire trucks, ambulances).
  • Added navigation and routing into the vision-based neural network for real-time handling of blocked roads and detours.
  • Added additional Speed Profile to further customize driving style preference.
  • Improved handling for static and dynamic gates.
  • Improved offsetting for road debris (e.g. tires, tree branches, boxes).
  • Improve handling of several scenarios including: unprotected turns, lane changes, vehicle cut-ins, and school buses.
  • Improved FSD’s ability to manage system faults and recover smoothly from degraded operation for enhanced reliability.
  • Added alerting for residue build-up on interior windshield that may impact front camera visibility. If affected, visit Service for cleaning!

Elon Musk shuts down Tesla ‘AMG’ division speculation: ‘Focus is autonomy’

“I think it’s best to leave that to the custom shops. Tesla’s focus is autonomous cars, building futuristic autonomous cars. We want the future to look like the future.”

Tesla CEO Elon Musk was asked by Joe Rogan late last week whether the company would ever consider establishing an “AMG division” like Mercedes-Benz has established for powerful, race-inspired vehicles.

However, Musk turned down any talk of that, highlighting that the company is laser-focused on autonomous vehicles, seemingly hinting that any distraction from autonomy would be a detriment to the future.

Rogan drives a Tesla Model S himself, but it is not your run-of-the-mill all-electric sedan. Already outfitted with the Plaid powertrain that Tesla developed, Rogan took his vehicle to Unplugged Performance for a true performance outfitting.

The vehicle is completely overhauled with performance parts and seats. Known as the Model S-APEX, Rogan took delivery of it from Unplugged in January.

Rogan asked Musk on Friday during his most recent appearance on the Joe Rogan Experience podcast whether Tesla would ever establish an “AMG division” that would focus on catering Teslas to performance-based standards.

Musk said:

“I think it’s best to leave that to the custom shops. Tesla’s focus is autonomous cars, building futuristic autonomous cars. We want the future to look like the future.”

Tesla fans have said for years that the company should consider acquiring Unplugged Performance and its Upfit Tesla division, which recently outfitted the Las Vegas Metropolitan Police Department’s fleet of Cybertruck cruisers.

However, it seems Tesla will keep things separate. Musk is primarily focused on autonomy, which will drive the technology forward and drive shareholder growth. Something like an outfitter for performance would be a cool thing for the owners who have the interest and the money.

It’s not a tremendous revenue driver or anything that would contribute to the financial state of the company. Mercedes-Benz, for example, is more accessible for consumers as it sold over 140,000 units from its AMG brand in 2024.

It helps with driving revenue higher by as much as 15 percent compared to similar models that are not AMGs. However, would Tesla see this much of a benefit? Likely not, because the Performance trim already caters to many owners.

Tesla Cybertruck fleet takes over at SpaceX’s Starbase

Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.

Tesla Cybertrucks have taken over at SpaceX’s Starbase facility in Texas, as hundreds of the all-electric pickup trucks were spotted late last week rounding out a massive fleet of vehicles.

The Cybertruck fleet is geared toward replacing gas vehicles that are used at Starbase for everyday operations. The only surprise about this is that it was not done sooner:

Deliveries have been going on for a few weeks, as Cybertrucks have made their way across the state of Texas from Austin to Starbase so they could be included in SpaceX’s fleet of vehicles at the facility.

Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.

However, there are some other perspectives to consider as SpaceX is utilizing such a massive fleet of Cybertrucks. Some media outlets (unsurprisingly) are seeing this as a move of weakness by both Tesla and SpaceX, as the aerospace company is, in a sense, “bailing out” lagging sales for the all-electric pickup.

It’s no secret that Tesla has struggled with the Cybertruck this year, and deliveries have been underwhelming in the sense that the company was anticipating between 1 million and 2 million orders for the vehicle before it was widely produced.

A lot of things changed with the Cybertruck between its 2019 unveiling and 2023 initial deliveries, most notably, price.

The price of the Cybertruck swelled significantly and priced out many of those who had pre-ordered it. Some have weighed the option of whether this purchase was a way to get rid of sitting inventory.

However, it seems more logical to consider the fact that SpaceX was likely always going to transition to Teslas for its fleet, especially at Starship, at some point.

It doesn’t seem out of the question that one Musk company would utilize another Musk company’s products, especially considering the Cybertruck has been teased as the vehicle that would be present on Mars.
