Before going on vacation around July 4th holiday, PlugInsights sent a short survey to me with questions about Tesla supercharging procedures and also about recent comments by Elon Musk. About half way into the short survey, it delves into Elon Musk’s supercharging “overuse” comment regarding some daily Tesla commuters relying on the free charging stations in southern California.

My first thought, this again. Musk’s comments made some waves last month but why dredge this issue to the surface in the form of a survey from PlugInsights, a division of RECARGO.

Is something afoot at Tesla? Why is the company worried enough to conduct a survey about this topic and especially Musk’s comments at the annual shareholders meeting. One question from the survey actually discusses the actual comments by Musk. “Before today, were you aware that Mr. Musk recently made these statements?”

Below are Musk’s comments at the recent annual shareholders meeting held in June:

(paraphrased via the survey)…”that superchargers are meant for free, long-distance travel” and “that drivers who aggressively use the network for local charging may receive an email reminder that it’s ‘cool to do this occasionally but it’s meant for a long-distance thing.’

So why did Elon Musk comment on this relatively small issue? Ashley Vance recent biography on Elon Musk points out that Musk usually doesn’t get involved in PR, unless an issue threatens one of his companies. So how could this threaten Tesla Motors? My speculation is the very real possibility of  battery capacity loss and drastically reduced range with multiple instances of DC fast-charging on a daily basis.

Could these patterns lead to drastically reduced battery packs ranges by year three or four of ownership and possibly lead to Tesla replacing a lot of battery packs, due to their warranty coverage?

My speculation centers around 120 kW of DC energy flowing into the battery pack on a daily basis. Did Tesla test battery packs for multiple, daily DC-charging usage? Maybe not.

Musk mentioned at the annual shareholder meeting that fast charging was intended for destination traveling and implied it wasn’t for daily use by commuters.

The Idaho National laboratory conducted a study on DC fast-charging and its effects on battery packs some years ago and released findings in 2014. Using 2012 Nissan Leafs, the study compared the effects of different types of charging: level 2 charging (3.3 kW) and DC fast-charging (50 kW).

The study revealed after 40,000 miles of testing that there was little loss of initial capacity and that the DC-fast charging battery pack had only lost 3 percent more than the other Nissan Leaf using level 2 battery charging.

However, Tesla Superchargers are dishing out 120 kW DC versus the Idaho study of 50 kW, more than 2x the amount of electricity coming into battery pack. That’s a lot stress on the battery management system to keep heat levels down, plus these car owners are supercharging daily, maybe doing it twice a day?

Many automakers have said that DC fast charging is fine on the battery pack, as long as it’s not done excessively. It seems twice a day could be considered excessive and cause concern for Tesla execs. This could be leading up to some proviso with excessive supercharging and the battery pack warranty, hence the PlugInsights survey on usage and expectations.

What about you, any other thoughts on why this is such an issue for Tesla?

** My other mild theory is Tesla’s rising electricity costs for owners employing supercharging only mode. The results of PlughInsights survey showed that 26% of Model S owners polled have used Tesla Superchargers as a free local alternative to home charging.

Tesla reveals plans for Robotaxi charging hub in Austin

Tesla has revealed plans through permit submissions for a massive Robotaxi charging hub in Austin, Texas.

Tesla plans to build the Supercharger hub in multiple phases, with the second phase potentially introducing wireless induction charging, something the company has been developing for the Robotaxi fleet.

Initially, 48 Tesla Robotaxi-geared Superchargers will be built on a lot just across from the St. Elmo, Texas, Service Center. There are about 80 additional spots that will not be impacted by phase 1 of the construction process.

Filings show that the second phase of the project will turn those 80 additional spots into wireless charging for Robotaxi, but it might be an error. The Key Notes state that item 3 is listed as “V4 Charging Cabinet to Support 80 Wireless Chargers in Phase 2. However, the drawings point to V3 Cabinets that are already tied to Superchargers:

There are roughly 128 total spots in the lot, but it is unclear if they will all be used for charging based on what appears to be some sort of typo in the blueprint.

This is among the first Robotaxi charging hubs Tesla has started to develop, as it currently has four others planned throughout various areas: one in Phoenix, one in San Antonio, another in Irving, which will serve the Dallas-Fort Worth area, and another in Las Vegas.

These projects are necessary as Tesla expands its Robotaxi program. Now that preparations have started for the public launch of Cybercab, Robotaxi will likely be expanding aggressively, especially over the next two to three years.

Last night, The Information reported that Tesla was planning to launch Cybercab as soon as the end of August. Hours later, Tesla then announced it was launching a competition for fans to potentially ride in Cybercab during its first public rides.

Tesla Cybercab launch preparations have begun

Tesla’s plan to expand its charging infrastructure in the regions where Robotaxi will initially operate is great preparation for the expanding service. There is still a lot to do, including launching the Cybercab on time.

Tesla got its largest order for the all-electric Class 8 Semi yet, a 500-unit order from Einride AB, a Swedish trucking company.

Einride made the announcement this morning following its second-quarter earnings call. The company said it plans to use 500 Tesla Semi units on its fleet intelligence platform, called Saga AI. The deployments will serve large companies like Amazon and will extend Einride’s electric freight network across logistics routes in California, New Jersey, Texas, Illinois, and Georgia.

The deployment is being carried out in several phases over the next two years as Tesla ramps production of the Semi at its dedicated production facility in Sparks, Nevada. Einride will receive its first Semi units in September.

Saga AI

Saga AI is Einride’s dedicated fleet intelligence platform. It enables scaled adoption of electric trucks for freight use and allows shippers to integrate electric capacity without the operational burden or capital risks of managing a fleet. This helps integrate cost-efficient logistics and makes budgeting and forecasting much more accurate.

Tesla Semi’s Adoption

The Tesla Semi is now gathering large-scale clients past those who have helped the company operate a Pilot Program to gain initial information and feedback from real-world drivers.

Perhaps the biggest and most notable is that of Frito-Lay and PepsiCo., who have worked with Tesla for the past several years to dial in the finer details of the truck, including its efficiency and operation-related components.

There has been tremendous progress in that time, and it even catalyzed Tesla to make some design changes, which were unveiled earlier this year.

But Einride CEO Roozbeh Charli says his company’s partnership with Tesla will continue to push those things forward:

“This deployment is yet another proof point that we can execute at the scale our customers demand. Working closely with Tesla to bring next-generation Semis into active operations quickly and at scale is a testament to the strength of that partnership, and how quickly this technology is maturing from promise to daily operations.”

Additionally, Dan Priestley, the Director of the Semi Program at Tesla, said the partnership is ideal due to Einride’s focus on sustainable transport:

“Einride is at the forefront of sustainable freight, and we are thrilled to deepen our relationship with them through this order of 500 Semis. EV heavy trucks provide lower costs per mile from fuel savings, reduced maintenance, and better uptime over diesel trucks. These savings increase further through operational efficiency when deploying EV trucks at scale, and we are excited that Einride recognizes this and look forward to supporting their deployments.”

India tells Elon Musk’s X to “Follow the Law” in latest censorship update

Elon Musk says X now exposes government censorship, but India’s secrecy laws complicate that promise.

Published

By

Elon Musk’s promise to make government censorship requests on X “clearly visible” is running into a wall in India, where the law forbids the very disclosure Musk is promising.

On August 15, Musk responded to an update from X’s open-source algorithm team by writing “Any censorship required by governments is now clearly visible.” The claim referred to a change X pushed two days earlier to its public xai-org/x-algorithm repository, which now includes a controversial filter written directly into the code. The filter suppresses posts from 665 accounts flagged by Brazil’s Superior Electoral Court from appearing in the For You feed of any viewer located in Brazil, unless the viewer already follows the account. The election tied to the filter is scheduled for October 4.

India’s government wasn’t as impressed, and responded on Monday that “X will have to follow the law of the land,” in response to Musk’s transparency push covered by the Times of India. The problem is structural rather than political. India issues content blocking orders under Section 69A of its IT Act, and Rule 16 of the accompanying 2009 Blocking Rules requires those orders to stay confidential. Publishing an India equivalent of the Brazil filter, naming specific accounts and citing specific government orders, would itself violate Indian law. Government use of Section 69A has grown from roughly 6,000 orders a year between 2018 and 2023 to about 24,300 in 2025, according to a Tech Times report.

Elon Musk shares details on X vs. Brazil conflict

The contrast puts Musk’s transparency pledge in an odd spot. It works largely as advertised in Brazil, where electoral law requires disclosure and X can point to specific account IDs and a specific court order in public code. It cannot work the same way in India, where the law requires the opposite. X users in India will keep seeing content disappear from search and their feeds without any public accounting of why, even as X tells the rest of the world that its censorship compliance is now inspectable.

This isn’t the first time X’s fights with a national government have shaped how the platform operates. Brazil’s Supreme Court ordered X to suspend the accounts of sitting lawmakers and journalists in 2024, a standoff that cost X its Brazilian revenue for months and froze Starlink’s local accounts before the investigation into Musk and X was closed in March with no evidence of wrongdoing found. X also sued California over a state law requiring moderation disclosures, arguing the mandate itself violated the First Amendment.

Whether India’s government pursues anything beyond a public statement remains to be seen. For now, the mismatch between what X can legally publish and what different governments legally allow it to publish is the real story behind Musk’s seven word claim.
