Electrify America edges out Tesla Superchargers in 2021 EV Charging Infrastructure Benchmark
Last year, global engineering firm umlaut, which performs benchmarks in various industries, adapted its testing prowess to the United States’ electric vehicle market to determine which public charging network was the best in the country. The effort, which was dubbed as the inaugural 2020 USA EV Charging Infrastructure Benchmark, determined that Electrify America was by far the best public charging network in the United States.
But while the inaugural USA EV Charging Infrastructure Benchmark was notable, there was a popular network that was not included in umlaut’s first analysis: the ubiquitous Tesla Supercharger Network, which is very prevalent but not open to the public like Electrify America. This was why in this year’s USA EV Charging Infrastructure Benchmark, the global engineering firm made it a point to include the Supercharger Network in its study, even if the system had to be scored quite differently due to it being specifically designed for Tesla’s electric cars.

For the 2021 USA EV Charging Infrastructure Benchmark, umlaut performed a comparative study of the country’s fast-charging networks and rated each one using several criteria, specifically: interoperability, pricing, transparency, functionality, and availability, among others. A Tesla Model 3 and a Ford Mustang Mach-E were selected as the vehicles that would used for the study. The EV pair covered 2,100 miles over six days to test charging stations across Michigan, Ohio, Maryland, New Jersey, New York, Connecticut, and Pennsylvania.
To rank the different charging networks, umlaut opted to split its analysis into two areas: the “Digital Platform,” which includes a service’s website and mobile app, and the “Charging Location,” which includes ease of payment, amenities, and the technical performance of the system itself. The results, interestingly enough, revealed that Electrify America was still the overall winner with 702 points due to its balanced scores in the “Digital Platform” and “Charging Location” categories.

Tesla’s Supercharger Network was a second with an overall score of 649. This was quite interesting as Superchargers completely dominated the “Charging Location” metric, earning a perfect score in “Technical Performance” and high scores in the “Access and Payment” subcategories, among others. However, the Supercharger Network lost points in the “Digital Platform” category since Tesla’s website and mobile app were not as useful as those of other networks. This was, of course, partly due to the fact that Tesla’s Supercharger sessions were already integrated into the company’s vehicles themselves.
Despite the challenges presented by the Supercharger Network in this year’s 2021 USA EV Charging Infrastructure Benchmark, umlaut’s Christian Sussbauer noted that Tesla’s charging systems excel in numerous key areas.

“We had a lot of internal discussions about including Tesla Superchargers in this year’s Benchmark because we really want to create a testing system that will capture the right metrics and provide the most useful information to the EV industry. To be honest, if you asked me before we conducted the tests, I think I would have predicted that Tesla Superchargers would end up leading in total points because it’s well known that they do a great job in many aspects of fast charging. And actually, our test results show this clearly—Superchargers excel in many important areas. It’s actually a little boring to test Supercharger stations because you just plug them in, and they reliably work.”
“We were happy to find a very high level of simplicity and reliability with Electrify America this year as well. Using an EV with Plug & Charge enabled on Electrify America’s network was a very good user experience. All of the EV industry should strive to replicate that aspect of Superchargers and Electrify America/Plug & Charge. And in the end, Electrify America also has a very useful smartphone app and website that combined to put them over the top in terms of total points scored for the metrics we were measuring in 2021,” Sussbauer said.

SpaceX’s Gwynne Shotwell just made a quiet gesture toward Tesla
SpaceX president Gwynne Shotwell quietly followed Tesla on X, and merger watchers noticed right away.
SpaceX President and COO Gwynne Shotwell has started following Tesla’s official account on X, a small change that landed in the middle of a very loud merger conversation. Whole Mars Catalog joked about it on Sunday.
A follow is not an announcement, and neither company has said anything about a deal. What gives the moment weight is the timing. Barclays analyst Dan Levy has told clients that an agreement could come before Tesla’s annual meeting, which must be held by December 6, with SpaceX as the buyer in an all stock deal, as we reported after the Roadster unveiling. Wedbush’s Dan Ives has stuck with a 2027 timeline.
“Shit, I better start following their X account if i’m gonna be helping run the company”

Shotwell is the executive most worth watching if the two companies do move closer. When Musk was asked at the All In Summit why Tesla and SpaceX remain separate, Shotwell sat next to him and said SpaceX personnel had already moved into xAI to fill leadership and engineering gaps. The businesses were integrating “faster than I thought,” she said, though “not fully integrated yet.” Her responsibilities have also grown since SpaceX absorbed xAI, and she now oversees operations that include Grok and the company’s AI compute buildout.
The financial links are already there. Tesla’s $2 billion xAI investment turned into a stake of less than one percent in SpaceX, the two share the Terafab chip project in Austin, and Musk exercised his 2018 Tesla options a week after SpaceX began trading, a sequence analysts flagged as giving SpaceX public shares to use in a deal. Musk holds about 20 percent of Tesla and controls 85.1 percent of SpaceX’s voting power, according to our earlier breakdown.
The next test is close at hand. SpaceX reports its second earnings as a public company on Tuesday after the close, and Tesla follows on Wednesday. Musk told analysts in July that “we can’t talk about combining companies and that kind of thing on an earnings call,” so a direct answer is unlikely from either stage. Tesla shareholders can still submit and vote on questions through the Say portal until 4 p.m. EDT on Monday, and the merger is a recurring theme in the queue.

Tesla Roadster owners to get “Flying Stunt Mode” and looping track access
Musk says Roadster owners can command the unveiling stunts autonomously, with a Texas looping track.
Elon Musk says owners of the new Tesla Roadster will be able to ask the car to perform the stunts Tesla showed at its unveiling, with the car doing the driving itself. Musk made the comment Saturday in a reply on X to tech blogger Robert Scoble, and he added a promise of a looping track at Tesla’s Texas headquarters.
Scoble had argued that the person in the Roadster is not really driving it. In his description, the driver operates a computer that tells another computer what to do, with steering, braking and acceleration all handled by wire. Musk answered, “True. You will be able to ask the Roadster to perform any of the tricks shown autonomously, as it will be sentient. Also, we will have a wild looping track (crazier even than Hot Wheels) at our Texas HQ where you can test out your Roadster.”
@Scobleizer True.

At the October 15 event outside Waco, the car drove up a curved ramp until it was upside down, flew off on cold gas thrusters, flipped and landed. It also hovered over a Cybercab, Cybertruck, Semi, Model Y and Model 3 while moving. As we noted in our breakdown of the three Roadster configurations, Musk said at the event that the car “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. Saturday’s reply adds that the car would run them on its own.
Tesla has described some of the hardware that would make that possible. The Roadster uses steer by wire with a yoke, and its cold gas thrusters rely on electric actuators for small adjustments in flight. A fan system under the car creates suction, which Tesla says is strong enough to hold it upside down, a setup we covered in our look at the Roadster’s fan system and thrusters.
Musk did not say when an autonomous stunt feature might arrive, how it would work, or what he means by sentient. He also gave no size, location or opening date for the Texas track. Production is planned for Giga Texas in 2027 or 2028, and Tesla says the car is not approved for public road use. The Rocket version, the one built to fly, is invite only.
The comment follows a week of Musk teasing the event, including his claim that the demo would be a banger, which we covered before the stream. Tesla reports third quarter earnings on October 21, and shareholders can submit and vote on questions through the Say portal until 4 p.m. EDT on October 20, according to our earnings Q&A preview. A question about autonomous Roadster stunts and the Texas track would be a quick way to get specifics from management.

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.
