Why Musk is supporting former Exxon Mobil CEO for Secretary of State
Elon Musk shocked social media when he tweeted an endorsement of Rex Tillerson as the next US Secretary of State on Tuesday. Musk has a few good things to say about Donald Trump leading up to his Presidency and Trump’s choice of the former CEO of Exxon Mobil seems to be a slap in the face to anybody who is concerned about global warming and the role fossil fuels have played in it.
Exxon Mobil is currently being investigated by the attorneys general of the New York and Massachusetts. Both contend the company knew of the harm that burning fossil fuels could do to the environment 40 years ago but elected to spend billions funding special interest groups to oppose the climate change message being put forth by James Hansen, The Union of Concerned Scientists, and others.
Weaning the world off fossil fuels is one of the central themes of Elon Musk’s plan to build compelling electric cars and promote solar power. What could he possibly find appealing about the CEO of the largest oil company in the world?
Yesterday, The Economist endorsed Tillerson and Musk tweeted shortly afterwards that he agreed with The Economist.
This may sound surprising coming from me, but I agree with The Economist. Rex Tillerson has the potential to be an excellent Sec of State.

Musk added, “Rex is an exceptionally competent executive, understands geopolitics and knows how to win for his team. His team is now the USA. I share The Economist’s opinion that he should be given the benefit of the doubt unless his actions prove otherwise.
Has Elon deserted his loyal fans who tend to be rather more ecologically aware than the norm? Apparently not. Later in the day, he revealed the reason why he supports Tillerson for Secretary of State.
Rex Tillerson supports a carbon tax. This is what is really needed to move the needle. https://t.co/6ne01TOzs1

Musk is betting that Tillerson will be able to influence Donald Trump to accept a carbon tax, something Musk has been advocating for since he first joined Tesla Motors. It is a way to eliminate what economists refer to as an “untaxed externality,” something that is a cost of doing business that is not incorporated into the price of finished goods.
Musk delicately refers to the fact that fossil fuel companies largely avoid paying the environmental and societal costs of their activities as “the turd in the punchbowl.” During the COP21 Paris climate summit, he made a compelling case for a carbon tax to a distinguished audience at the Sorbonne. In Tillerson, he seems to believe he has an important ally.
Musk has also been present at a number of meetings with Donald Trump, leading some to question whether his apparent support for the new President could alienate some of Musk’s traditional supporters. Until now, Musk and Tesla have been careful not to become embroiled in the divisive political storm that is roiling America.
Treading carefully between the needs of his businesses, the needs of his customers, and the policies of the new government may be one of the toughest challenges Musk has ever faced. Uber, for instance, has suffered a backlash from people incensed that CEO Travis Kalanik has accepted an appointment to one of Trump’s policy forums for business leaders. Musk is also a member of the same forum, but so far there has been no political backlash against Musk and Tesla.
Tesla is doing what Trump wants other car companies to do — build more American factories that employ American workers. But SpaceX is dependent on NASA for a significant portion of its future income. Of all Musk’s business ventures, it can least afford to alienate the current occupant of the Oval Office.
Musk may have made a carefully calibrated political calculation with regard to his working arrangements with the administration, but his support for and trust in Rex Tillerson seems to be grounded in the belief that a carbon tax is vital step to the fight to limit the damage from the consumption of fossil fuels. Unless and until he does something to break that trust, Tillerson and Musk will remain what Washington watchers for decades have called “strange bedfellows.”

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
Investor's Corner
Tesla’s flying Roadster just revealed something bigger than the car
Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.
The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.
Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.
The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.
The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.
Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.
The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

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

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.

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.
