Kimbal Musk trolls Fox with ‘Plant a Seed Day’ in exchange about Tesla’s new chair
It appears that the art of trolling runs deep between the Musk brothers. While Elon Musk is known to troll on Twitter from time to time, the trolling chops of Kimbal Musk have mostly been untapped. That is, of course, until recently, when Kimbal ended up aggravating Fox Business Network host Stuart Varney by trolling him with a barrage of plugs for “Plant a Seed Day,” an initiative from his nonprofit, Big Green, that aims to encourage American families to plant a seed on March 20, 2019.
During the amusing segment, the Fox Business host attempted to ask Kimbal about Robyn Denholm’s activities as Tesla’s new chair. Denholm, who has been with the board since 2014, and who has experience in both tech and auto companies as a finance executive, was named earlier this month as a replacement for the outgoing Elon Musk, who was forced to vacate his Chairman post as part of his settlement with the SEC. Denholm’s appointment was widely supported by Elon Musk and Tesla’s supporters, who noted that he was looking forward to working closely with the finance veteran.
It did not take long before Denholm’s appointment attracted some creative speculations among Tesla’s critics. Headlines such as “Tesla’s New Chair Is Part of the Furniture,” “Tesla’s New Chair Won’t Do Much to Rein In Elon Musk,” and “Taming Elon Musk: New Tesla chair, board members face a tough job” have been prevalent since Denholm’s appointment, suggesting that there might be a certain degree of conflict between Musk and the new chair as she attempts to keep the CEO in line.
Varney’s questions towards Kimbal Musk during the short-lived interview suggest that he was traversing a similar line. “Look, Kimbal, you are on the board at Tesla. And you’ve got a new chair. Have you heard anything from her? You’ve got to tell me, is she laying down the law? Have you had contact with her? What’s she saying? What’s she doing on the board?” the Fox Business host asked.
Kimbal Musk, for his part, proved immovable, simply stating that he was “so happy for the future of Tesla.” He also mentioned Plant a Seed Day on March 20, 2019, where his nonprofit, Big Green, aims to get a million American families to plant a seed in their backyards. During the course of the brief interview, Kimbal plugged Plant a Seed Day five times, much to the chagrin of the Fox Business host.
A visibly upset Varney eventually decided to throw in the towel, saying “You think my viewers want to learn about plant a seed day? Do you really? They don’t care, Kimbal. They don’t care!” Kimbal, for his part, continued plugging Plant a Seed Day, stating that the event is “going to be awesome.” At that point, Varney opted to cut the interview.
“Okay, okay. I’m wrapping it up, I’m sorry. Wait a minute, I am responsible to my audience. I’m sorry it’s over. I will not be used,” Varney said, visibly aggravated.
Plant a Seed Day is being coordinated by Big Green, Kimbal Musk’s nonprofit whose mission is to promote and foster a healthy food lifestyle for America’s schoolchildren. A centerpiece of Big Green’s initiatives is the Learning Garden, which are modular gardens that are set up in schools where children could plant and harvest crops. In a blog post on Medium, Kimbal noted that Plant a Seed Day is working with “national and international distribution, brand, and sponsorship partners” to get over 1 million seeds to families for March 20, 2019.
“At Big Green, when my team works with a new Learning Garden school, we encourage teachers to have their students draw out their dream garden. It’s one of my favorite activities because this is when the magic begins. Kids will draw unicorns watering tomato plants, banana trees growing next to their school, or plants that talk, walk, and water themselves. The creativity and energy put toward creating a dream garden is endless. Soon the children realize the real magic of a garden is in planting a seed, watering it, caring for it, and watching it grow.
“Planting a seed is the first and powerful step to making a big change in food education. We have seen this critical step taken thousands of times in the schools we work with through Big Green. On March 20, 2019 we will bring those magical moments to millions of children.”

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash
An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.
An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.
Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.
The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.

Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.
The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.
Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.
Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.

Tesla crosses major Unsupervised Self-Driving milestone
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 Robotaxi will be a 24/7 service: here’s when
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.
