Tesla and the danger of soft budget constraints
The Wall Street Journal is not always friendly to Elon Musk and Tesla Motors. In an article published August 16, staff writer Holman Jenkins, Jr. suggests that Tesla is one election away from extinction. Why? Holman bases his analysis on a study of John Z. DeLorean and an economic principle known as soft budget constraints.
The study by Graham Brownlow of Queen’s University Belfast was published in October, 2014. It says one of the foundations for DeLorean’s start-up car company was the willingness of the British government to subsidize the enterprise with grants, tax breaks, government backed loans, and other political incentives.
In 1975 when DeLorean Motors began, conflict between Protestants and Catholics in Ireland was at a fever pitch. The economy of Northern Ireland was in tatters and the British government was desperate to attract manufacturing jobs to the area. DeLorean promised to do just that and the government responded with open arms.
Brownlow says the support from the government amounted to what economists refer to as soft budget constraints, meaning the company never had to turn a profit. In effect, as DeLorean boasted at the time, the government was in so deep, it had no choice but to continue funding the operation. In layman’s terms, its like having rich parents and knowing they will cover your losses no matter how foolishly you spend your money.
Jenkins says Tesla Motors is similarly positioned. It is the beneficiary of several indirect government subsidies such as federal and state tax credits, HOV stickers, and the like. He also claims the company benefits from direct government support in the form of loan guarantees and corporate tax credits. Taken together, they provide Tesla with the ability to exceed normal budgetary constraints on a regular basis.
He prefers what he would term the more traditional model, as laid out by Brownlow. “The more [an entrepreneur] expects that the existence and growth of the firm will depend solely on production costs and proceeds from sales, the more he will respect the budget constraint,” Brownlow writes.
Jenkins hints darkly that Musk’s recent decision to bring the start of production of the Model 3 forward by 2 years is a ploy designed to force the federal government to extend the tax credit program for buyers of electric cars. Tesla will be bumping up against the 200,000 vehicle limit in total US sales by the time that car goes on sale.
He also thinks the merger between Tesla and SolarCity is intended to mute the criticism that Teslas are not as environmentally friendly as they are touted to be, since the majority of electricity in the United States comes from burning fossil fuels like natural gas and coal.
Jenkins reminds readers that John DeLorean’s dream came crashing down once Margaret Thatcher came to power. She turned off the financial spigot that had propped him up, with predictable results. The implication is that Tesla is just one election away from a similar fate.
Jenkins could be the designated cheerleader for all the people who have shorted Tesla stock. The comments appended to his story in the Journal make it clear his opinions have plenty of enthusiastic supporters, many of whom view Elon Musk as little more than a scam artist.
In his efforts to advocate for a level playing field where every corporation pays all its bills on time, pays all its taxes, never accepts a hand out from the government, and always does the right thing, he conveniently overlooks the $5 trillion a year in direct and indirect subsidies the International Monetary Fund says are provided to the fossil fuel industry every year.
There is a coda to the DeLorean story, one that is seldom told. It is said that John Z personally selected the spot where his factory in Northern Ireland would be built. The Irish have a long and steadfast belief in what they call “the little people.” We call them leprechauns.
According to the story, the site DeLorean chose required the removal of a whitethorn tree. Now, everyone knows the little people build their homes in the roots of whitethorn trees. Uprooting one is guaranteed to bring some seriously bad mojo down on your head.
What happened to DeLorean only proves that legend may be more powerful than economic theory. The antidote to Jenkins’ gloomy predictions may be to inform Elon he must never cut down a whitethorn tree to build one of his factories.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
