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.

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.
Tesla is going to let you guide Full Self-Driving with Grok in 3 months, CEO Elon Musk confirmed on X.
The response from Musk, which revealed Tesla plans to allow drivers to effectively control the car and its navigation more explicitly using Grok, puts the feature for about September.
A Tesla owner said that Full Self-Driving is great, but owners should be able to “converse with Grok like we can with an Uber driver.” She then used examples like, “Grok, turn right here,” and “Drop us off right here, we’ll walk due to traffic,” and finally,” Drop at entrance first, then park far away.”
Coincidentally, the final piece of dialogue would also mean features like Banish are potentially on the way soon.
This functionality will be there in about 3 months or so

Banish is also referred to as “Reverse Summon,” and would enable the car to self-park while dropping occupants off at their destination.
This would be a great way to improve the overall experience while supervising FSD. Navigation is already a major painpoint that many owners complain about. Manual overrides when a maneuver is requested or canceled (like using the turn signal stalk to override a navigation route), do not always work.
The feature could be especially useful in street parking scenarios in a city, where spots are sometimes tough to come by. Many of us who grab dinner in a more populated area will park a street or two over from wherever we’re going, because sometimes you know that’s the best you will get. If a driver using FSD could say, “Hey Grok, turn right here on Queen St. and park in that open spot on the right,” it could save a lot of confusion FSD might have on its own.
Musk teased that a similar feature was “coming” back in February:
Tesla Full Self-Driving set to get an awesome new feature, Elon Musk says
It is certainly surprising that Tesla is doing it at this point. The company’s more recent moves have been more evident of taking control and inputs away from humans and putting them in the AI’s hands more frequently. The biggest example of this was taking away Max Speed in AI4 cars, giving us Speed Profiles, and not having any input on the fastest speed the car will travel.
Of course, giving navigation preferences to Grok is availble already in Teslas, but not at the drop of a hat. Instead, you can suggest a certain route at the beginning of your drive.
Here’s an example of that from December:
🚨🏈 I am taking my parents and Fiancee to the @Ravens game next weekend and asked @Grok to help me route my @Tesla through a specific neighborhood to reach the correct Lot we will park in.
This is a great example of the new @grok nav integration with the Tesla Holiday Update: pic.twitter.com/rPp4I7q8Yv

Finally, the original post that Musk responded to mentioned a parking preference after dropping off the occupants, which describes the Banish feature that Tesla has teased for years.
We’re not sure if Musk was responding more to the ability to guide the car with Grok, or whether he also was including Banish in the three-month prediction timeframe.
A close-up image of a Cybercab engineering vehicle in Peabody, Massachusetts, reveals a compact triangular side repeater camera housing equipped with an integrated washer mechanism.
This seemingly small hardware addition could prove to be one of the most critical components for achieving reliable, unsupervised Full Self-Driving (FSD) — not just for the dedicated Robotaxi but potentially for existing AI4-equipped vehicles as well.
The washer system’s importance cannot be overstated in Tesla’s vision-only autonomy approach. Cameras are the sole sensory input for the neural networks powering FSD, constantly interpreting the environment for safe navigation. In real-world conditions, however, lenses quickly accumulate rain, snow, mud, dust, or road spray.
Many of us Tesla owners, especially those who deal with any sort of winter weather at all, know the all-too-common alert that pops up when cameras are obstructed:
Even brief obstructions can drop perception confidence, trigger safety disengagements, or force the vehicle to pull over, although these are relatively rare. Instead, most of the time, the camera will need a wipe from the owner next time they stop the car.
But unlike human drivers who can manually clear their view, a Robotaxi operating 24/7 without a steering wheel or mirrors must maintain pristine vision autonomously. The Cybercab’s side repeater washer delivers targeted cleaning bursts precisely where needed for merging, lane changes, and blind-spot monitoring — functions that demand uninterrupted visibility from the external cameras:

This hardware directly tackles a known pain point in current FSD deployments. Owners frequently report camera-related alerts during inclement weather, which is understandable, but needs to be solved for a true autonomous experience.
For a production Robotaxi fleet aiming for high utilization and minimal downtime, robust washer systems represent a foundational reliability upgrade; essentially, they’re a must-have. Early sightings suggest the design may extend to rear cameras as well, creating a comprehensive cleaning architecture that keeps the entire vision suite operational in harsh environments.
Without it, even the most advanced neural nets struggle when their “eyes” are compromised.
What Does This Mean for AI4 Cars?
This Cybercab detail raises timely questions for AI4 cars already on the road. While Hardware 4 delivers superior compute and camera resolution compared to earlier versions, production models typically lack dedicated side and rear washers. Tesla has included them on Model Y robotaxis that it is using in the fleet:
Tesla Robotaxi has a highly-requested hardware feature not available on typical Model Ys
As Tesla refines unsupervised FSD for broader release, the gap in environmental resilience becomes evident. Software improvements can help mitigate issues, but they cannot fully replace physical cleaning in heavy rain or muddy conditions. Analysts and owners increasingly speculate that AI4 vehicles may eventually require similar washer retrofits — or a future AI4.5 variant — to match the Cybercab’s all-weather readiness and support the same level of autonomy.
As testing progresses, the Cybercab’s washer mechanism highlights Tesla’s pragmatic focus on real-world robustness. It may well become the hardware piece that determines how quickly and reliably FSD scales from prototypes to everyday vehicles.
