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 has reached a notable benchmark in its autonomous driving program after its Robotaxi fleet surpassed one million miles of unsupervised operation. The company made the announcement during its Cybercab event in Austin on September 3.
Tesla Vice President of AI Ashok Elluswamy told attendees he was happy to report the fleet had achieved one million miles of unsupervised Robotaxi operation as a testament to safety.
The new total marked a sharp increase from the 380,000 unsupervised miles Tesla disclosed during its second-quarter 2026 earnings update in late July.
In roughly six weeks, the company added about 620,000 miles. That acceleration followed Tesla’s decision to remove in-vehicle safety monitors from most of its operations outside the San Francisco Bay Area.

Tesla first launched Robotaxi service in Austin in June 2025 with safety drivers present. It later began fully unsupervised rides and expanded into Dallas, Houston, Miami, Orlando, and Tampa. The San Francisco Bay Area remains the exception, where a safety monitor still rides in the vehicle under California permitting rules.
The company has not released a city-by-city breakdown of the one million unsupervised miles.
The milestone arrived as Tesla began offering public Cybercab rides in Austin. The purpose-built vehicle has no steering wheel or pedals and is designed only for autonomous ride-hailing. Production versions joined the existing fleet of modified Tesla vehicles already operating in the service.
Tesla’s unsupervised mileage is growing at a double-digit weekly rate according to earlier company comments, yet its fleet size remains modest compared with established competitors. Waymo has accumulated more than 200 million fully autonomous rider-only miles. Tesla has described its own unsupervised operations as having recorded zero notable incidents in the period leading up to the July update.
The one-million-mile figure reflects Tesla’s shift from supervised testing to broader driverless service in multiple states. It also highlights the company’s strategy of using both existing Model Y vehicles and the new Cybercab to scale its network.

Whether the rapid recent growth continues will depend on further city expansions, regulatory approvals, and the performance of the purpose-built Cybercab in everyday paid rides. Tesla has not specified how many of the latest miles involved the new vehicle versus the rest of the fleet.
The announcement underscores Tesla’s progress toward a larger robotaxi network while illustrating the remaining gap in total autonomous experience relative to longer-operating rivals.
Tesla AI lead Ashok Elluswamy said this week that 24-hour Robotaxi service is close. Replying on X to a rider who wanted Cybercab trips all night, he wrote that the capability would arrive “next month or so” once “the next tech to merge on the v15 plan” is ready.
The comment landed on September 4, one day after Tesla opened public Cybercab rides in Austin. It is the clearest near-term timeline yet for overnight unsupervised operation. Tesla’s paid Robotaxi network currently runs from 6 a.m. to 10 p.m. seven days a week across Austin, Dallas, Houston, Miami, Orlando, and Tampa.
next month or so. the next tech to merge on the v15 plan will enable it.

That 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.
Elluswamy did not name the specific feature or say whether the change would apply first to purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list. The link to Full Self-Driving v15 is nevertheless significant.
Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.
By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states with what the company called an impeccable safety record and no notable incidents caused by the vehicles themselves. Tesla has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.
Overnight service would test that claim in lower-light conditions and would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.
Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale: Tesla has held back mass expansion until more of the v15 stack is merged, citing the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.
If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets.
That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.
It may also engage if we…

The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
