Elon Musk’s Boring Company becomes frontrunner for Ontario Airport high-speed tunnel
It appears that Elon Musk’s tunneling startup, The Boring Company, is poised to secure a high-profile contract to build the Ontario Airport Loop, a high-speed transport tunnel connecting Rancho Cucamonga with the Ontario International Airport. The Boring Company’s tunnel will be a faster and more cost-effective alternative to above ground rail projects, which were previously proposed for the route.
The new Boring Co. project has received widespread support from the San Bernardino County Transportation Authority’s Board of Directors, who voted unanimously in favor of the system. As noted by The Mercury News, the Board of Directors also directed staff to postpone a $3 million study that explores other airport-rail connection options.
According to San Bernardino County Supervisor Curt Hagman, the Boring Company’s transport tunnels are a great, affordable alternative to more traditional rail systems, which take far longer to construct. Hagman was actually able to see the Boring Company’s technology in person, having visited the startup’s Hawthorne site and taken a test ride through the test tunnel.
“It gets us thinking in a new way. This is something that can be done relatively quickly and inexpensively,” he said.
The Boring Company’s Rancho Cucamonga-Ontario Airport tunnel will be 2.8 miles long. The tunnels themselves will be 14 feet in diameter and about 35 feet underground. For now, the proposal involves using electric vehicles with rubber tires traveling up to 127 mph from point to point, though plans are reportedly also underway to introduce electric vans for the transport system.
These electric vans are capable of seating up to 12 people and their luggage. The vehicles, which are being developed by Tesla, will boost the capacity of the system to about 1,200 per day, or over 10 million per year provided that they see a mass rollout. These electric vans seem very similar to the Boring Company’s mass transport units that were mentioned back when the startup was being considered for the Chicago Airport transport line.
The Ontario Airport Loop is expected to cost between $45-$60 million, though the project’s entire cost could reach about $75 million when the price of adding an operations center, management services, and operators’ wages is added. Yet despite this, $75 million is still a far cry from the estimated $1-$1.5 billion light rail extension that was also being considered.
The Boring Company’s Ontario Airport Loop is expected to be completed in about four years, far quicker than the 10 years that the construction of a light rail extension requires. Carrie Schindler, SBCTA director of transit and rail, explained this in a statement to local news outlets. “It is much more cost-effective. I do anticipate the need for outside funding but at a reduced level as compared to building surface projects,” the transit and rail director said.
The Boring Company may have only been around for a few years, but the tunneling startup seems to be hitting its stride with its projects. Prior to the Ontario Airport Loop, the Boring Co. has been contracted to build a Loop system for the Las Vegas Convention Center, which would allow visitors to the expansive site to travel from one end of the complex to the other in just a few minutes. The progress of the Las Vegas Loop has been quick, with the digging of both tunnels being completed recently.
Tesla just gave what is perhaps its biggest signal yet that the launch of the Cybercab, its autonomous ride-hailing-geared car, is imminent.
The Cybercab has been spotted outside of Gigafactory Texas in massive numbers over the past few days, with hundreds of units being stored on property just days after the vehicle received a Certificate of Conformity from the EPA.
Today, things were a bit different.
Cybercabs spotted on Giga Texas property today had an addition: a Cybercab decal on the side, reminiscent of the “Robotaxi” ones that were placed on Model Ys just as the company launched its ride-sharing platform about a year ago.
Giga Texas drone operator Joe Tegtmeyer noticed the change today:

Tesla could be signaling that the Cybercab is preparing to enter the Robotaxi fleet in the coming weeks or months with this move. It seems more symbolic than anything; Tesla is ready to throw Cybercabs in the ride-hailing platform just as it did with Model Ys last year.
The addition of the Certificate of Conformity awarded to the Cybercab is another major factor working to Tesla’s advantage. The company now has permission from the EPA to allow the vehicle to operate on public roads and enter the chain of commerce. It’s officially street legal.

The big question that remains is whether Tesla will be able to operate the car without a safety monitor, especially considering it plans to put the car out there without a steering wheel or pedals. With the Cybercab only having a seating capacity of two, it is hard to believe Tesla will even consider putting a Safety Monitor in the car.
It did recently self-certify as Level 4 and has the ability to operate driverless vehicles in the State of Texas under a law that took effect on May 28. You can read more about that here:
Tesla’s Robotaxi dreams just took a massive step toward reality
We’d imagine Cybercabs will be on the roads as soon as July, but August will likely be a better estimate of when the car will be entered into the Cybercab fleet. It all depends at where Tesla is, as they’ve truly prioritized safety with the rollout of the Robotaxi platform.
Elon Musk has publicly questioned Moody’s credit assessments following the rating agency’s decision to assign SpaceX a Baa1 investment-grade rating, two notches above Tesla’s Baa3. The comments came amid discussions comparing the two companies’ financial profiles.
SpaceX earned its first-time Baa1 rating with a stable outlook from Moody’s. The agency highlighted the company’s leadership in orbital launches, the growing recurring revenue from its Starlink satellite network, strong vertical integration, U.S. government contracts, and emerging opportunities in AI infrastructure.
These factors were cited as supporting robust cash flows, margin expansion, and financial flexibility.
Musk responded directly: “Tesla’s credit rating is ridiculously low tbh,” and added, “Yeah, makes no sense. Tesla has over $40B in cash, no debt, and is consistently profitable!” His remarks underscored Tesla’s balance sheet strength and profitability at a time when many traditional automakers continue to report losses in the shift to electric vehicles.
Yeah, makes no sense.

Tesla maintains a leading position in the global EV market, with diversification into energy and storage, battery technology, and robotics through projects like Optimus. Recent financial updates show the company generated positive free cash flow of $1.4 billion in Q1 2026, supported by operating cash flow of $3.9 billion. Cash and short-term investments stood at approximately $44.7 billion.
Moody’s has affirmed Tesla’s Baa3 issuer rating with a stable outlook in periodic reviews, acknowledging the company’s EV leadership, technology strengths, including AI for autonomous vehicles, solid profitability, and strong liquidity.

However, the agency has also noted challenges in the automotive segment and expectations for margin pressures.
Musk’s critique highlights a common debate about how traditional rating methodologies apply to high-growth, capital-intensive technology companies. SpaceX benefits from long-term government-backed contracts and diversified, recurring revenue streams, while Tesla’s valuation reflects heavy investment in future technologies such as autonomy and robotics.
Both ratings remain investment-grade, yet the one-notch difference has fueled online discussion about potential inconsistencies in evaluating innovative firms.
The exchange comes as SpaceX explores financing options following its recent valuation milestones, while Tesla continues executing on its multi-year roadmap. Musk’s pointed response serves as a reminder that credit ratings, though influential for borrowing costs, represent one lens through which markets assess corporate strength—and that company leaders often view their financial positions through the lens of long-term innovation and cash generation rather than short-term risk metrics alone.
A new report from Reuters claims that a transport authority in Sweden is pushing back against the approval of Tesla’s Full Self-Driving suite because it will travel over speed limits.
The report says the Swedish Transport Administration (TRV) recommends the European Union votes against FSD’s approval. TRV believes it should not be approved until Tesla disables FSD’s ability to speed.
TRV sent a letter to the European Union’s Technical Committee on Motor Vehicles (TCMV), which is set to meet on June 30 to discuss the potential approval of the Tesla FSD suite in the country. Tesla, which has received various approvals in Europe over the past two months, has not provided a comment.
Teslas operating on FSD do travel over the speed limit, depending on the Speed Profile that is chosen. Drivers have the ability to disengage FSD at any point; Tesla specifically states that those supervising the suite are responsible for its actions.
Let’s cut to the chase: humans operating any vehicle speed almost daily in the United States. Realistically, speed limits in the U.S. are more frequently treated as speed minimums. However, other countries are different, and driving behaviors are less aggressive.
TRV believes that “allowing automated systems to systematically exceed legal speed limits…risks undermining both the legal framework and the expected safety benefits of vehicle automation,” the report stated. It’s surprising that Tesla has not received this claim from other countries previously.
This could be a good argument to bring Max Speed back, the setting that previously allowed the driver to choose the absolute fastest the car would travel.
This would still put the responsibility of supervision in the hands of the driver. It would allow the driver to choose whether the car would travel over the speed limit or not, acknowledging that they set the speed, and if they get pulled over, there would be no ability to argue it.
However, it does not seem as if this is something Tesla will do, especially considering many U.S. drivers have requested the feature in an effort to eliminate speeding or at least tone it down. The company has not shown any interest in bringing it back.
Tesla has approvals for FSD in Europe in Estonia, Lithuania, Denmark, the Netherlands, and Belgium.
