How Tesla Battery Day can silence critics once and for all
The hype surrounding Tesla’s Battery Day is very real. Enthusiasts and unknowns are talking about the potential findings that Elon Musk and his crew could unveil on September 22nd, and the event could make way for Tesla to become much larger than it already is. However, there is a good chance that the critics of the electric automaker will have little to say after the event, and if Tesla plays it right, it could be the beginning of the end of the Tesla FUD (Fear, Uncertainty, Doubt) movement.
It is understandable to assume that Tesla doubters will always exist. Some companies that have the best intentions still have their haters, and that’s just human nature. While Tesla will always have people who will doubt its intentions as a company, Battery Day could be the proverbial duct tape over the lips of the most vocal skeptics.
Tesla still has work to do, and Battery Day’s total appeal comes down to whether the company can manage to live up to the hype. Many rumors are circulating around what Elon Musk could unveil at the event, some related to batteries, and some aren’t. But whatever happens, it really comes down to the “Wow” factor, and whether Tesla can manage to attain that with their findings and unveilings.
To me, the most significant thing Tesla could announce is price parity, and something that is relatively an extra is the possibility that Musk could unveil the Plaid Powertrain. But if the company really wants to make a mark, several things, in my opinion, have to be confronted during the event.
Million-Mile Battery
Tesla’s Million-Mile Battery is almost certainly the most confirmed element of Battery Day. Developments from Jeff Dahn and his team of researchers have come up big for Tesla recently with electrolyte solutions and new studies that show revolutionary energy density measures. Reports across the globe have essentially confirmed that Tesla will unveil this development at the event, and it will be a big win for the electric automaker.
Having a battery that will last as long as two or three vehicle chassis means that when the increased longevity is combined with increasing production, Tesla will have a relatively large-scale supply of batteries available at their disposal. This opens the doors for many things, including price parity and the possibility of becoming a supplier for other electric car companies.
Price Parity…or close to it
Price parity with gas cars wouldn’t only be monumental for Tesla, but for EVs in general. It would prove that gas cars are not always going to be the most economical option for drivers, and the price of battery-powered cars would drop. Having Tesla announce price parity or something close would mean the premium EV brand would have the most affordable vehicles in terms of EV tech and range. It could mean the company’s growth may accelerate much quicker than initially anticipated. If the cars are cheaper, a lot of people will buy them, obviously. While $35,000 is reasonable for the Model 3 Standard Range, many people still are unwilling to spend that much on any car.
Getting the price of batteries down would literally begin the destruction of legacy automakers as if it hasn’t already started. Tesla being the best EV brand and having the best prices per kWh would be so massive, I don’t think many people can begin to fathom the possibilities.
This is a preview from our weekly newsletter. Each week I go ‘Beyond the News’ and handcraft a special edition that includes my thoughts on the biggest stories, why it matters, and how it could impact the future.
Status as a cell supplier for other companies
If Tesla can figure out price parity and long lifespan battery cells, the company will be well on its way to becoming a battery supplier. Long term battery life, combined with affordability, will be a big plus for Tesla’s plans to become a supplier for other EV brands. Having cheap batteries that are high-quality and offer an extended lifespan will be a no brainer. Tesla’s most notable competitors will be forced to source their cells from the Silicon Valley-based company.
Plaid Powertrain for the Model S
The Plaid Powertrain has been highly-anticipated for about a year, and there is a good chance Tesla unveils it at Battery Day. It seems that the issue with putting it into production last year was along the same lines as putting the Semi into production too early: battery shortages. The Plaid Powertrain will have a larger pack, meaning more cells, and putting it on Tesla’s menu too early would have spoiled their plans for the cars that are more crucial to the future of the company. The Model 3 is an excellent example of this. It’s a mass-market car, and the batteries should go toward these efforts instead of a sedan that has increased performance.
The Semi was not put into production because battery cells were not plentiful enough. Creating the Semi and fulfilling the preorders that the company had would have been troublesome for Tesla’s mass-market vehicle push, and it certainly wouldn’t have been the smartest strategy. However, Musk said that a “volume production” push of the Semi needed to occur soon, which basically confirms that the shortage is no longer an issue. The Plaid Powertrain will likely be the next piece of Tesla’s puzzle to be announced.
Is there the possibility that Tesla will shock us with something completely unexpected?
Of course, we’re talking about Elon Musk. The guy that unveiled the next-Gen Roadster as a surprise and the guy that rolled off a Cyberquad after the Cybertruck unveiling. While those are just a vehicle and a four-wheeler, we’re talking about Tesla’s most anticipated event, perhaps ever. There is a lot of potential for groundbreaking announcements next Tuesday, and there is no shortage of things that Musk could announce.
He has said on numerous occasions that Battery Day is going to be insanity and that it will likely blow a lot of minds. But what will transpire exactly, only a few people really know, and there is little sense in trying to guess what Musk will have for us on September 22nd.

GM CEO Mary Barra says she told Biden to give Tesla and Musk EV credit
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
General Motors CEO Mary Barra said in a new interview on Wednesday that she told President Joe Biden to credit Tesla and its CEO, Elon Musk, for the widespread electric vehicle transition.
She said she told Biden this after the former President credited her and GM for leading EV efforts in the United States.
During an interview at the New York Times Dealbook Summit with Andrew Ross Sorkin, Barra said she told Biden that crediting her was essentially a mistake, and that Musk and Tesla should have been explicitly mentioned (via Business Insider):
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
GM CEO Mary Barra said to Andrew Sorkin at the New York Times Dealbook Summit that she pulled President Biden aside and said Tesla CEO @elonmusk deserved the credit for EVs:

Back in 2021, President Biden visited GM’s “Factory Zero” plant in Detroit, which was the centerpiece of the company’s massive transition to EVs. The former President went on to discuss the EV industry, and claimed that GM and Barra were the true leaders who caused the change:
“In the auto industry, Detroit is leading the world in electric vehicles. You know how critical it is? Mary, I remember talking to you way back in January about the need for America to lead in electric vehicles. I can remember your dramatic announcement that by 2035, GM would be 100% electric. You changed the whole story, Mary. You did, Mary. You electrified the entire automotive industry. I’m serious. You led, and it matters.”
People were baffled by the President’s decision to highlight GM and Barra, and not Tesla and Musk, who truly started the transition to EVs. GM, Ford, and many other companies only followed in the footsteps of Tesla after it started to take market share from them.
Elon Musk and Tesla try to save legacy automakers from Déjà vu
Musk would eventually go on to talk about Biden’s words later on:
“They have so much power over the White House that they can exclude Tesla from an EV Summit. And, in case the first thing, in case that wasn’t enough, then you have President Biden with Mary Barra at a subsequent event, congratulating Mary for having led the EV revolution.”
In Q4 2021, which was shortly after Biden’s comments, Tesla delivered 300,000 EVs. GM delivered just 26.

Tesla Full Self-Driving shows confident navigation in heavy snow
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease.
Tesla Full Self-Driving is getting its first taste of Winter weather for late 2025, as snow is starting to fall all across the United States.
The suite has been vastly improved after Tesla released v14 to many owners with capable hardware, and driving performance, along with overall behavior, has really been something to admire. This is by far the best version of FSD Tesla has ever released, and although there are a handful of regressions with each subsequent release, they are usually cleared up within a week or two.
Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
However, adverse weather conditions are something that Tesla will have to confront, as heavy rain, snow, and other interesting situations are bound to occur. In order for the vehicles to be fully autonomous, they will have to go through these scenarios safely and accurately.
One big issue I’ve had, especially in heavy rain, is that the camera vision might be obstructed, which will display messages that certain features’ performance might be degraded.
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease:

I found the steepest, unplowed hill in my area and tested the following:
• FSD 14.2.1 on summer tires
• FSD 14.2.1 on winter tires
• Manual drivingBut I think the most impressive part was how FSD went DOWN the hill. FSD in the snow is sublime $TSLA pic.twitter.com/YMcN7Br3PU

Well.. I couldn’t let the boys have all the fun!
Threw the GoPro up and decided to FSD v14.2.1 in the snow. Roads were not compacted like the other day, a little slippery, but overall doable at lower speeds. Enjoy the video and holiday music 🎶

Moving into the winter months, it will be very interesting to see how FSD handles even more concerning conditions, especially with black ice, freezing rain and snow mix, and other things that happen during colder conditions.
We are excited to test it ourselves, but I am waiting for heavy snowfall to make it to Pennsylvania so I can truly push it to the limit.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”
