The Professor was looking forward to getting a new US driver’s license. After moving from the East Coast to teach at the University of California, it became pertinent for the 38-year old engineer and scientist to have his own driver’s license again. The coming school year would be different from the last, after all, and with face-to-face classes likely starting again, it was important for the Professor to have the capability to drive the family’s Tesla Model 3 when needed.
Having extensive driving experience overseas before moving to the United States, the Tesla owner (name witheld as requested) was fairly optimistic that he could pass the Department of Motor Vehicles’ standards. His family certainly looked forward to it, so his wife, who also teaches at the University of California, and their two kids — a 4-year-old and a 3-month old baby — headed over to the Santa Ana DMV. Unfortunately for the Professor, he made a grave mistake.
He drove a Tesla.
Driving Tests from Hell
It is no stretch to state that California is the heart of the US’ electric vehicle transition. It’s home to Tesla’s headquarters and the company’s Fremont Factory, where vehicles like the Model 3 and the Model Y are produced. The Professor was then surprised when the DMV examiner, after what appeared to be an uneventful drive, told him that he had failed his driving test. As related to Teslarati, the DMV examiner reportedly informed the Tesla owner that he failed because the “technology in the car was not off.” When asked for more explanation, the examiner explained that the Model 3’s acceleration should have been on “Chill Mode” and the steering settings in “Comfort.”
This was inconvenient, but the Professor figured that he should probably just try again. The Model 3 owner ultimately opted to try his hand at another test in the LA DMV, especially since Teslas are extremely common in Los Angeles. For the second time, the family of four headed over to the LA DMV in their Model 3 for another test. The Professor then drove away with his examiner, but not before ensuring that the Model 3 was in Chill Mode and its steering was set in Comfort. But just like his previous attempt, the DMV examiner informed the Tesla owner that he had failed because of the Model 3’s “automatic engage.” Explaining further, the examiner stated that she could feel the brakes even when the physical brake pedal was not being pressed.

This set off alarms in the Professor and his wife, as regenerative braking is a feature that is very common among electric vehicles. It is also not in any way connected to a Model 3’s automated features. As they addressed their concerns with the DMV, the manager of the LA office told the Model 3 owners that there was no way for Teslas to disable their automated features. When the Tesla owners asked where she got her information from, the manager stated that she heard it from a customer who visited the DMV a few weeks prior. The manager then extended an offer, telling the Tesla owner that he could retake the exam that same day if he could rent a traditional car.
This was an unexpected turn for the family, but they were eventually able to secure a Toyota Camry from a rental car company an hour away. But upon presenting the vehicle to the DMV, the LA office rejected the Camry since it was not under the Professor’s name. Ultimately, the Tesla owner was not allowed to take his driving test in the rental car, though he was given the option of renting one from the LA DMV office instead for $140, $40 more than the Camry that the family had initially rented. Unfortunately for the Professor, he was given a failing score once more, despite the DMV examiner acknowledging that he seemed to have a lot of experience driving cars.
DMV Policies and Customer Advice
In a later message, the Professor’s wife stated that her husband would most definitely try to get his driver’s license once more, though they would probably wait some time before trying again. The last three tries were quite exhausting, and by the third driving test, the Model 3 owner stated that some DMV staff were already irate. This was not that unusual, of course, considering that the DMV is one of America’s least-liked agencies. It was just quite surprising that in the first two tests, it was the Model 3’s features that caused the examiner to fail the Tesla owner.
In a response to a Teslarati inquiry about the Model 3 owners’ experience, the CA DMV Public Affairs Office confirmed that there is no policy that prevents customers from taking their driving test in a Tesla. The office added that while the DMV currently has no specific criteria for features like regenerative braking in EVs, it is working to ensure that examiners have an understanding of the function and how it impacts driving. That being said, the agency advised that those who wish to take their driving test in a Tesla should speak to a manager first to avoid issues.
“In the event (that) a customer has questions about taking a driving test in a particular vehicle, they should ask to speak with a manager before the test. DMV employees who give behind-the-wheel tests receive updated training as necessary,” the DMV Public Affairs Office noted.
It should be noted that California is arguably the US state that is friendliest to electric vehicles. The state still offers clean vehicle rebates, and there is still a Zero Emission Vehicle (ZEV) mandate for automakers. It is then no surprise that Teslas are very popular in the state. In 2015, California accounted for 43% of Tesla’s new vehicle registrations, as per data from IHS Markit. This percentage has since decreased as Tesla started selling its cars to more territories — but its California stake is still no joke. In 2020 alone, Tesla still sold 37% of its vehicles in California, despite the pandemic and the company no longer having any access to the $7,500 federal tax credit enjoyed by competitors like the Ford Mustang Mach-E and the Volkswagen ID.4.

Insights from CA’s Clean Air Protectors
The California Air Resources Board (CARB), which is charged with protecting the public from the harmful effects of air pollution and developing programs to fight climate change, is among the agencies that are helping push the transition to sustainable transportation. With this in mind, it seemed appropriate to get the agency’s take on the Tesla Model 3 owners’ experience with the Santa Ana and LA DMV. After all, it would be quite challenging to fully adopt electric vehicles in California if some driving examiners or DMV offices were still unfamiliar with how EVs work, or their features for that matter.
CARB Communications Specialist John Swanton informed Teslarati that while driving tests are not CARB’s area of responsibility, the agency could work together with the DMV if there are widespread issues that could impede the greater goals of California’s transition to Zero-Emission vehicles. That being said, Swanton remarked that driver-assist technologies are becoming more and more common in modern cars, and they are widely accepted as features that enhance safety.
“While the driver’s license test is not our area of responsibility, we can say that we are not aware of any serious concerns that DMV has with the routine features found in a very wide range of vehicles equipped with driver-assistance technologies. As you are probably aware, these are in use in both EV and combustion-powered vehicles, and are widely accepted to enhance vehicle safety. These systems not only meet state requirements; they are fully certified for use nationwide by the US National Highway Traffic Safety Administration,” Swanton said.
The CARB Communications Specialist further stated that specific features like regenerative braking have long been proven to be very efficient, driver-operated controls that have been utilized since the early days of hybrid vehicles like the Toyota Prius. In this light, at least, it appears that the DMV examiner’s statements about the Model 3’s regenerative braking being an automated feature seems misinformed at best or biased at worst. “Their operation is not unlike the use of an automatic transmission. So it’s safe to say that these are not autonomous features, but rather simply part of modern automobile controls. I think this complaint may be a situation with an individual examiner that DMV management will need to speak to or clarify policy,” Swanton remarked.

Behind the Times
There is something ironic about the idea of a Tesla driver in California failing a driving test because of the electric vehicle’s basic functions. Numerous driving schools across the globe, after all, are already embracing electric vehicles fully. Los Angeles-based Drivers Ed Direct currently operates an all-electrified fleet of cars for its students. Defensive Driving School, which was founded in 1945, actually offers a “specialty course” on Model 3s called “The Tesla Experience.” These programs suggest that driving schools across the country are already aware that sustainable vehicles are inevitable, and it is in everyone’s best interest to ensure that drivers of the future are fully acquainted with the features and behavior of electric cars.
And it’s not just the United States either. In Germany, a country famous for its mastery of carmaking, schools like Die Fahrschule have made it their mission to ensure that the next generation of drivers is properly prepared for the era of electric vehicles. In an interview with noted EV advocate Ove Kröger, one of the German driving school’s instructors, Alexander Erler, stated that there are actually advantages to teaching in an EV like a Model 3, since the vehicles provide a calm atmosphere. Remarkably, Erler noted that the presence of Model 3s in the school’s fleet actually helped dispel misinformation about electric vehicles, especially when younger drivers take their EV-skeptical parents along for their lessons.
Even oil-rich Dubai is no different. Electric vehicles are still a niche product in the Middle Eastern city, but prominent driving schools like Emirates Driving Institute (EDI) are already investing in electric vehicles. The school purchased a Model X to be part of its premium driving fleet in 2018, and since then, the vehicle has been received well. In a conversation with Teslarati, EDI Marketing Executive Disha Bhatia explained that the addition of electric vehicles to the school’s fleet is fully supported by the government. This is a big vote of confidence in EVs, since Dubai mandates all drivers to attend a formal driving school before attempting a driving test.
“It becomes important for them to also know that if tomorrow, electric cars are the future, then how would driving be any different than that of regular cars? So when (the students) learn on Teslas, they would understand the differences between a normal car versus an electric car. However, they also need to understand that driving is the same. They still need to focus on the same points… the same (focus on safety)… We’ve received great responses from a lot of our customers who are very interested to drive in a Tesla, and they’re very happy to get their licenses,” she said.
So what exactly happened in the case of the Model 3 owner? It would be very difficult to determine exactly what caused the examiners to fail the Tesla owner, though it appears that a lack of proper information is the prominent culprit. Teslas are ultimately cars, after all, and they serve the same purpose as regular vehicles. They just happen to be more advanced, and in more ways than one, safer, than traditional vehicles. With this in mind, it seems to be a bad idea to be misinformed about Teslas, especially since the vehicles are practically everywhere in the state.

Tesla’s two defunct flagship models are getting a big upgrade
Tesla’s two recently-defunct flagship models, the Model S and Model X, are getting a big upgrade, according to the company’s Head of AI, Ashok Elluswamy.
Older Hardware 3 Model S and Model X vehicles have been the last major holdouts in Tesla’s Full Self-Driving v14 Lite rollout, and that wait now appears to be ending.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
At Tesla’s Cybercab launch, AI chief Ashok Elluswamy told Ryan McCaffrey that he thought the S and X build “was supposed to go out last week.” Evidently, Elluswamy expects the suite to be rolled out to those HW3 Model S and Model X very soon:
For my @Tesla friends – and specifically Model S & X owners with HW3 who are waiting on FSD v14 Lite – I spoke to @aelluswamy at the Cybercab launch, & when I asked for an ETA on v14 Lite for S/X owners, he said, “Oh, I thought it was supposed to go out last week.”
So: soon! 🙌
— Ryan McCaffrey (@DMC_Ryan) September 7, 2026
Those cars are not the current Model S and Model X, which already ship with Hardware 4. They are the pre-refresh flagships built around Tesla’s older Autopilot computer, often called HW3 or AI3.
Tesla stopped putting that computer in new vehicles years ago, which is why owners treat these S and X cars as a closed generation. Model 3 and Model Y vehicles on the same computer began receiving v14 Lite in late June 2026 and saw a wider North American expansion in July. South Korea followed as an early international market. The S and X versions of the same software never joined that wave.
v14 Lite is Tesla’s way of squeezing the current v14 driving stack onto hardware that cannot run the full AI 4 model. The company describes the process as distillation: behaviors learned on the newer computer, including reinforcement learning and offline models, are compressed so the older chip and cameras can use them as a guide.
Early descriptions put the distilled network at roughly 15 percent of the original size. The result is still supervised Level 2 driving. Tesla has been clear that HW3 cannot support unsupervised Full Self-Driving or robotaxi operation because of memory and bandwidth limits.
The feature list is what made the wait so frustrating for S and X owners, as plenty of new features are to be shipped with it.
Official notes for the first Lite build, firmware 2026.20.5.1, added parking, unparking, and reversing; arrival options for a parking lot, street, driveway, or curbside; speed profiles that stay available at all times; and start-from-park engagement. Tesla also claimed better handling of merges, forks, pedestrians, traffic lights, and cut-ins, plus fewer false slowdowns and smoother lane centering.
A mid-July follow-on build, 2026.20.6.10, added more of the Hardware 4 interface, including a standalone Self-Driving app and the ability to start a trip from Park without a brake-pedal confirmation.
Elluswamy called that version the one “likely going to wide release.”
That wide release already reached most other HW3 cars in the United States and Canada. International timing still depends on regional validation and regulatory approval. For S and X owners, the remaining work appears to be model-specific validation rather than a new software stack.
There is no official Tesla changelog or build number for those two models yet, only Elluswamy’s offhand timeline. Some HW3 drivers who already have Lite report large gains over v12.6; others have described new indecision or phantom braking. The next test will be whether the same software lands cleanly on the older flagships that have waited the longest.
Cybertruck
This tiny Tesla Cybertruck adjustment has big advantages
Yesterday, we reported on Tesla Cybertruck getting some major adjustments from a manufacturing standpoint in an effort to make the all-electric pickup more cost-effective, more reliable, more serviceable, and more easily produced.
Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup
One of those changes was the addition of a self-reinforcing polypropylene aero shield that sits underneath the truck. Previously, Tesla utilized aluminum for this, but the self-reinforcing polypropylene was more durable while also being cheaper and lighter.
Tesla has revealed another small change it made to the Cybertruck, and it has to do with the side repeater cameras.
Tesla does not wait for a new model year to improve its vehicles. On September 8, Cybertruck lead engineer Wes Morrill posted side-by-side photos of an updated side repeater camera housing now rolling off the line at Gigafactory Texas.
The triangular camera pod mounted on the front fender looks almost identical at first glance. A closer look reveals a revised contour that uses the air already flowing around the truck to keep the lens clearer in rain and road spray.
The side repeater camera was updated – the version on the left is the newer part which uses passive geometry to create airflow disturbance that better keep water off the lens while driving. No cost penalty, just pure vision improvement. pic.twitter.com/wAbXtcL1Jf
— Wes (@wmorrill3) September 8, 2026
The side repeater cameras sit in an exposed position on the Cybertruck’s angular stainless-steel body.
In wet weather, they readily collect water droplets that can degrade the image Autopilot and Full Self-Driving use for lane changes and blind-spot monitoring. Early production trucks sometimes left owners wiping lenses by hand or accepting temporary restrictions on driver-assistance features.
Tesla has added washers to cameras on certain other models and on Cybercab prototypes, but those active systems add cost, complexity, and extra potential leak points.

The new housing solves the problem with passive geometry. Subtle changes in the surround create localized airflow disturbances as the vehicle moves. Those eddies physically push water droplets away from the optical surface. Morrill called the result “pure vision improvement” achieved at “no cost penalty.” Once the production mold is updated, every subsequent part costs the same as the original.
The advantages compound quickly. Clearer cameras in rain improve the reliability of driver-assistance features precisely when they are needed most. The design consumes no extra energy and introduces no new failure modes.
New Cybertrucks built after the tooling changeover receive the updated part automatically. Some owners of trucks delivered as late as June 2026 have already confirmed they received the revised housing. Retrofit questions have appeared in replies, and the cameras appear electrically compatible, though Tesla has not announced an official service program.
A few millimeters of reshaped housing will not make headlines the way a new battery pack does, but these changes are incremental and increase the Cybertruck’s effectiveness as a vehicle over time.
This improvement illustrates how Tesla continues to refine the Cybertruck after volume production began. Better wet-weather vision, zero added cost, and no extra hardware add up to a meaningful gain in everyday usability and safety.

Tesla is rolling out a new FSD version with a massive safety addition
Tesla is rolling out a new version of its Full Self-Driving suite to some owners that comes with the massive addition of a safety feature.
Tesla is rolling out Automatic Collision Evasion with the 2026.27.6 Software Update, which started rolling out to some vehicles last night. We received the update, along with Full Self-Driving v14.3.9, as well as v14.2 Lite, which has identical release notes as the previous version and seems to have some refinements and improvements in behavior and performance.
🚨 Tesla FSD v14.3.9 is rolling out as well as 2026.27.6 which includes Automatic Collision Evasion
Brand new safety features from a software update. My Tesla gets better everytime I get one of these pic.twitter.com/ctrMiQXWhM
— TESLARATI (@Teslarati) September 8, 2026
However, most of the attention has fallen on the Automatic Collision Evasion feature, which we covered in an article last week.
The function will activate Full Self-Driving to “try to keep your vehicle safe and then continue driving. It can engage in the following situations while you are driving manually:
- Scenario 1: A frontal collision is imminent and braking alone may not avoid it.
- Scenario 2: Your vehicle detects that you are not sufficiently attentive to the road (for example, reaching toward the back seat), or that Full Self-Driving (Supervised) may have been unintentionally disengaged.”
Essentially, FSD will take over when the vehicle determines you are not paying sufficient attention or are heading toward a potential collision. The addition of this feature is incredibly useful as distracted driving is a major issue in today’s world.
Along with the new safety feature is Tesla FSD v14.3.9, which has no additional release notes compared to the previous version, but in my first drives, my first impression is that operation is great, and parking is still sort of a pain point.
Just took a 15-mile round trip to the gym and back
Pretty on par with what FSD is nowadays – really good. Not enough time to see what’s good and what’s bad, but these first rides on any version feel shockingly good. They’re all pretty identical https://t.co/WN1qTg4bhE
— TESLARATI (@Teslarati) September 9, 2026
Additionally, Tesla v14.2. Lite has arrived. A great review of that is available here:
— Zack (@BLKMDL3) September 9, 2026
The addition of an Automatic Collision Evasion feature is similar to that of other collision avoidance systems that are used by companies like Hyundai, Kia, and Genesis. These programs typically utilize radar and camera sensors to apply emergency brakes autonomously, though evasive steering in a manual driving mode is pioneered primarily by Tesla’s newest addition.
