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.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY
— TESLARATI (@Teslarati) October 16, 2026
Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.
Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.
Roadster transforms in Track Mode
These aero features aren’t just for looks: they provide the best passive downforce package of any road car (approaching F1 levels!) with wing actuation driven by the @Tesla_Optimus actuator system https://t.co/AqrC4qUga9

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.
Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”
The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.
Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.
| Configuration | Seats | 0 to 60 mph |
|---|---|---|
| Performance | 2 | under 1.6 s |
| Thrust | 2 | under 0.9 s |
| Rocket | 1 | under 0.59 s |
Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.
Every car on the road today is limited by one thing: tire grip
Roadster’s thruster system generates 4–5x the force the tires can.
More force on the same mass means significantly better acceleration – physics does the rest https://t.co/zdPRT2aKwZ

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store
Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.
Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.
The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.
The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.
Just ask Grok @Bot to buy what you want someplace else and get a better deal.
There are far more purchasing websites than just Amazon!
— Elon Musk (@elonmusk) October 15, 2026
The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.
The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.
The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.
Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.
So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!
