Why are Tesla Superchargers Only for Long-distance Travel?

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 Board Chair discusses what is being done to protect CEO Elon Musk

Tesla Board Chair Robyn Denholm met with Bloomberg this morning to discuss a variety of topics, but perhaps one of the most interesting was her comments on what is being done to protect company CEO Elon Musk.
After the assassination of right-wing political commentator Charlie Kirk this week, there have been concerns about Musk’s safety, as well as that of other high-profile business leaders and political figures.
Earlier this week, Musk said himself that his security detail would be increased significantly following Kirk’s death, a move that many investors and fans of the company had requested because of political violence.
Elon Musk assures Tesla investors he will enhance his security detail
“Definitely need to enhance security,” Musk said. Tesla spent $3.3 million on Musk’s security in 2024 and January and February 2025. For reference, Meta spent over $27 million on Mark Zuckerberg’s security last year, which is higher than any other tech CEO.
During Denholm’s appearance on Bloomberg TV earlier today, she stated that the company has been focused on Musk’s security detail for “many years,” especially considering he is one of the richest people on Earth and holds an incredible amount of influence.
“It is something that we take very seriously; he takes it very seriously as well. So, again, from a board perspective, it is something we’ve discussed at length,” Denholm said.

Denholm added that she believes “there is not anyone in a boardroom that is not touched by what has happened with Charlie Kirk.”
Although Musk’s political involvement has toned down significantly in the past, he still has enemies, especially based on groups that oppose him and the company specifically. Based on this week’s events, it feels that increased security is a necessary expense Tesla must account for.

Tesla bear turns bullish for two reasons as stock continues boost
“I think from a trading perspective, it looks very interesting,” Nathan said, citing numerous signs of strength, such as holding its 200-day moving average and holding against its resistance level.

A Tesla bear is changing his tune, turning bullish for two reasons as the company’s stock has continued to get a boost over the past month.
Dan Nathan, a notorious skeptic of Tesla shares, said he is changing his tune, at least in the short term, on the company’s stock because of “technicals and sentiment,” believing the company is on track for a strong Q3, but also an investment story that will slowly veer away from its automotive business.
“I think from a trading perspective, it looks very interesting,” Nathan said, citing numerous signs of strength, such as holding its 200-day moving average and holding against its resistance level.
He also said he believes a rally for the stock could continue as it heads into the end of the quarter, especially as the $7,500 electric vehicle tax credit is coming to an end at the end of the month.
With that being said, he believes the consensus for Q3 deliveries is “probably low,” as he believes Wall Street is likely underestimating what Tesla will bring to the table on October 1 or 2 when it reports numbers for the quarter.

Tesla shares are already up over five percent today, with gains exceeding nine percent over the past five trading days, and more than fourteen percent in the past month.
While some analysts are looking at the performance of other Mag 7 stocks, movement on rates from the Federal Reserve, and other broader market factors as reasoning for Tesla’s strong performance, it appears some movement could be related to the company’s recent developments instead.
Over the past week, Tesla has made some strides in its Robotaxi program, including a new license to test the platform in the State of Nevada, which we reported on.

Additionally, the company is riding the tails of the end of the EV tax credit, as inventory, both new and used, is running extremely low, generally speaking. Many markets do not have any vehicles to purchase as of right now, making delivery by September 30 extremely difficult.
However, there has been some adjustments to the guidelines by the IRS, which can be read here:
Tesla is trading at around $389 at 10:56 a.m. on the East Coast.

Tesla lands regulatory green light for Robotaxi testing in new state
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.

Tesla has landed a regulatory green light to test its Robotaxi platform in a new state, less than three months after the ride-hailing service launched in Texas.
Tesla first launched its driverless Robotaxi suite in Austin, Texas, back on June 22. Initially offering rides to a small group of people, Tesla kept things limited, but this was not to be the mentality for very long.
It continued to expand the rider population, the service area, and the vehicle fleet in Austin.
The company also launched rides in the Bay Area, but it does use a person in the driver’s seat to maintain safety. In Austin, the “Safety Monitor” is present in the passenger’s seat during local rides, and in the driver’s seat for routes that involve highway driving.
Tesla is currently testing the Robotaxi platform in other states. We reported that it was testing in Tempe, Arizona, as validation vehicles are traveling around the city in preparation for Robotaxi.

Tesla is also hoping to launch in Florida and New York, as job postings have shown the company’s intention to operate there.
However, it appears it will launch in Nevada before those states, as the company submitted its application to obtain a Testing Registry certification on September 3. It was processed by the state’s Department of Motor Vehicles Office of Business Licensing on September 10.

It will then need to self-certify for operations, essentially meaning they will need to comply with various state requirements.
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
CEO Elon Musk has stated that he believes Robotaxi will be available to at least half of the U.S. population by the end of the year. Geographically, Tesla will need to make incredible strides over the final four months of the year to achieve this.
