Tesla sends cease-and-desist letter against ad claiming FSD will “mow down children”

It took a while, but Tesla finally seems to be putting some effort into curbing an aggressive and controversial anti-FSD ad that claims that the company’s advanced driver assist system is unsafe and will “indiscriminately mow down children.” A cease-and-desist letter from the electric vehicle maker has reportedly been sent to The Dawn Project, an advocacy group from Dan O’Dowd, the CEO of Green Hills Software, a company that is also developing self-driving software. 

The Anti-FSD Ad

Earlier this month, O’Dowd, through The Dawn Project, started pushing an anti-FSD ad that supposedly showed a Model 3 hitting a child-sized mannequin while FSD was engaged. The video and O’Dowd’s succeeding Twitter commentary were salacious, so it was no surprise that the ad’s allegations were echoed by numerous news outlets. The campaign attracted attention and criticism from Tesla supporters, however, some of whom proceeded to point out discrepancies in the anti-FSD ad. 

A number of FSD Beta testers, who have been using Tesla’s advanced driver-assist system for years, proceeded to conduct tests of their own, showing that FSD Beta does stop for people. Others observed that the driver of the Model 3 in O’Dowd’s test intentionally ignored safety warnings from the vehicle. Even EV fan blog Electrek pointed out a number of inconsistencies with O’Dowd’s supposed FSD test results and data, including a sequence in the ad when the advanced driver-assist system was not engaged at all. 

Cease-And-Desist

In its cease-and-desist letter, which was retrieved by The Washington Post, Tesla objected to the anti-FSD ad. The company alleged that the footage being pushed by O’Dowd was defamatory and misrepresented the capabilities of its advanced driver-assist system. Tesla demanded that the anti-FSD campaign be immediately halted and the videos be removed. 

“The purported tests misuse and misrepresent the capabilities of Tesla’s technology, and disregard widely recognized testing performed by independent agencies as well as the experiences shared by our customers,” Tesla deputy general counsel Dinna Eskin wrote. Tesla also accused O’Dowd’s team of “unsafe and improper use” of FSD Beta. “Your actions actually put consumers at risk,” the EV maker added. 

O’Dowd has reacted strongly to the letter. In a post on Twitter, O’Dowd noted that Musk was threatening to sue him. The Green Hills CEO included an incendiary illustration captioned with “Elon Musk’s Idea of Free Speech” on his post, which depicted Musk naked on his plane with a bound woman sandwiched between two male lawyers. The image seems designed to bait Musk, though Tesla itself has not issued a statement about its cease-and-desist letter.

“This letter is so pathetic in terms of whining: Mr. Free Speech Absolutist, just a crybaby hiding behind his lawyers,” O’Dowd told the Post. He also stated that he does not intend to take down his anti-FSD campaign. Instead, O’Dowd has pledged to put even more money into his anti-FSD efforts. 

Not the First Time

This is not the first time that Dan O’Dowd has put Tesla in his crosshairs. Earlier this year, O’Dowd ran for California Senate with the sole purpose of stopping Tesla’s driver-assist systems, which he claims are the worst he has seen. For context, O’Dowd has stated that his software never fails and is unhackable, a claim that has been challenged by cyber security advocates. 

Interestingly enough, Politico reported that O’Dowd actually did not plan to win a seat in the CA Senate at all — he was simply in the race because running for office entitled him to the lowest available ad rate in the run-up to the election. It also granted a higher degree of first amendment protection for his loaded claims against Tesla. Ultimately, O’Dowd ended up spending $3.8 million during his campaign — one of the most out of CA Senate candidates— but it resulted in him only getting 1.1% of the votes.

Elon Musk and Trump are closer than ever, and Tesla could be the big winner

Elon Musk sat beside Trump as AI leaders signed a voluntary White House safety accord.

Elon Musk had the seat right next to President Donald Trump on Tuesday as the White House hosted the leaders of America’s biggest artificial intelligence companies for a lunch that ended with a voluntary industry accord on AI safety.

A seating chart Trump posted on Truth Social placed Musk at the president’s left in the East Room, with Nvidia CEO Jensen Huang on his right, according to an Associated Press reporter. Anthropic CEO Dario Amodei, OpenAI President Greg Brockman, Meta’s Mark Zuckerberg, Google’s Sundar Pichai, Microsoft’s Satya Nadella and Amazon founder Jeff Bezos also attended, along with Vice President JD Vance and House Speaker Mike Johnson.

After the lunch, Trump told reporters outside the West Wing that the executives had signed “The White House Accord on Superintelligence: A Joint Commitment on Frontier SI Responsibilities.” Johnson described it as a voluntary statement of principles built on “robust internal controls and layers of internal and external review,” while Zuckerberg said company boards would independently review reports from outside auditors. Trump called the document “morally binding,” said he would name a new AI czar within days, and signed an executive order formally renaming artificial intelligence “super intelligence,” CNBC reported.

Musk was not in the room for Tesla alone. Since SpaceX absorbed xAI, he runs the company behind Grok and one of the largest AI training operations anywhere. On September 25, he said another 220,000 Nvidia GB300 chips would come online at Colossus 2 within a week, with more expected in November and December.

Musk also used the trip to restate his energy ambitions. “SpaceX is aiming together with Tesla to do 200 gigawatts of solar production per year,” he said at an event in Washington. It is the same combined target he laid out that feeds directly into Terafab, the Tesla and SpaceX chip venture that will need enormous amounts of power.

The showing between Musk and Trump has come a long way, since the two had the very public split in mid 2025 after Musk opposed the “Big Beautiful Bill” and left DOGE. They reconciled at Charlie Kirk’s memorial that September, and Trump later called their relationship “good”. Since then, Musk has joined Trump’s China delegation in May and attended last week’s White House state dinner for Chinese President Xi Jinping.

For Tesla, that access to government official could pay dividends. As Teslarati noted in January, federal autonomy rules, NHTSA oversight and a single national standard for driverless vehicles all run through an administration Musk can more easily reach directly as Tesla works to scale Robotaxi and Cybercab beyond Texas.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong

Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.

Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.

Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.

In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.

Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.
