Tesla bull calls battery cost declines “good deflation” that could boost EV sales
Longtime Tesla bull ARK invest recently identified battery cost declines as a form of “good deflation” that could lead to a boost in EV sales.
To support its observations, ARK Invest used the 2022 Nissan Leaf EV’s price as an example. A few years ago, Nissan announced that the 2016 Leaf SV and SL variants would come standard with its 30kWh battery pack for an EPA-rated 107 miles of range. Nissan’s suggested manufacturer’s prices for the SV and SL were $34,200 and $36,790, respectively. ARK calculated that the 2016 Nissan Leaf would cost ~$39,000 in today’s dollars.
Today, the 2022 Leaf with a 40 kWh battery pack costs $27,400, that’s $11,600 less than the 2016 version with an additional range of 42 miles. The Nissan Leaf’s pricing reveals that it costs less to produce an EV with more milage today than five years ago.
Battery cost declines could decrease EV production costs and improve range, which may boost electric vehicle sales in the long run. An increase in electric vehicle sales could lead to growth in the EV market.
In contrast to “good deflation,” ARK also identified an example of “bad deflation” in the auto industry, specifically in the used car market. The investment management firm noted a decline in used car prices over the past few months, indicated by the Manheim Used Vehicle Index.
“While [ARK Invest] believe[s] the decline in battery costs is likely to translate into lower prices, boosting EV sales, the drop in used car prices could be signaling weakening demand for traditional gas-powered cars,” wrote Sam Korus in ARK’s newsletter.
In its July 2021 publication, The Manheim Market Report (MMR) stated there were declines in prices every week last month. The used car market saw price declines accelerating through mid-July that slowed over the last two weeks. The MMR did not differentiate between used gas-powered vehicles or second-hand cars.
However, the used car market for EVs seems to be growing. Some countries, including the United States and Canada, are already considering tax credits and rebates for second-hand EVs.
As a frontrunner in the latest EV revolution, Tesla seems to be leading the charge in the used car market for electric vehicles as well. After making headways in the new passenger car market, the Tesla Model 3 had become a dominating force in the used car market in countries like the United States and the United Kingdom.
Given everything discussed above, it seems both forms of deflation ARK Invest discussed suggest that EV sales will increase, both in the new and used car market. More governments worldwide are readily committing to decreasing carbon emissions and transitioning to clean energy sources which would greatly affect the future of the auto market as well.

Tesla called ‘biggest meme stock we’ve ever seen’ by Yale associate dean

Tesla (NASDAQ: TSLA) is being called “the biggest meme stock we’ve ever seen” by Yale School of Management Senior Associate Dean Jeff Sonnenfeld, who made the comments in a recent interview with CNBC.
Sonnenfeld’s comments echo those of many of the company’s skeptics, who argue that its price-to-earnings ratio is far too high when compared to other companies also in the tech industry. Tesla is often compared to companies like Apple, Nvidia, and Microsoft when these types of discussions come up.
Fundamentally, yes, Tesla does trade at a P/E level that is significantly above that of any comparable company.
However, it is worth mentioning that Tesla is not traded like a typical company, either.
Here’s what Sonnenfeld said regarding Tesla:
“This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same. I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.”
Many analysts have admitted in the past that they believe Tesla is an untraditional stock in the sense that many analysts trade it based on narrative and not fundamentals. Ryan Brinkman of J.P. Morgan once said:
“Tesla shares continue to strike us as having become completely divorced from the fundamentals.”
Dan Nathan, another notorious skeptic of Tesla shares, recently turned bullish on the stock because of “technicals and sentiment.” He said just last week:
“I think from a trading perspective, it looks very interesting.”
Nathan said Tesla shares show signs of strength moving forward, including holding its 200-day moving average and holding against current resistance levels.
Sonnenfeld’s synopsis of Tesla shares points out that there might be “a little too much emphasis on the magic wand of Musk.”
Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever
This could refer to different things: perhaps his recent $1 billion stock buy, which sent the stock skyrocketing, or the fact that many Tesla investors are fans and owners who do not buy and sell on numbers, but rather on news that Musk might report himself.
Tesla is trading around $423.76 at the time of publication, as of 3:25 p.m. on the East Coast.

Tesla makes big change to Full Self-Driving doghouse that drivers will like
Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.

Tesla is making a big change to its Full Self-Driving doghouse that drivers will like.
The doghouse is a hypothetical term used to describe the penalty period that Tesla applies to drivers who receive too many infractions related to distracted driving.
Previously, Tesla implemented a seven-day ban on the use of Full Self-Driving for those who received five strikes in a vehicle equipped with a cabin camera and three strikes for those without a cabin camera.
It also forgave one strike per week of Full Self-Driving use, provided the driver did not receive any additional strikes during the seven-day period.
Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.
The change was found by Not a Tesla App, which noticed the adjustment in the Owner’s Manual for the 2025.32 Software Update.
The system undoubtedly helps improve safety as it helps keep drivers honest. However, there are definitely workarounds, which people are using and promoting for monetary gain, and you can find them on basically any online marketplace, including TikTok shop and Amazon:
🚨 Seeing more and more devices like this land on various online marketplaces including TikTok shop and Amazon
These devices are NOT to be used when operating Tesla Full Self-Driving and I’d love to see Tesla take action here.
These “creators” looking to make a quick buck are… pic.twitter.com/VnY25k2mPL

People are marketing the product as an FSD cheat device, which the cabin-facing camera will not be able to detect, allowing you to watch something on a phone or look through the windshield at the road.
The safeguards implemented by Tesla are designed to protect drivers from distractions and also protect the company itself from liability. People are still using Full Self-Driving as if it were a fully autonomous product, and it is not.
Tesla even says that the driver must pay attention and be ready to take over in any scenario:
“Yes. Autopilot is a driver assistance system that is intended to be used only with a fully attentive driver. It does not turn a Tesla into a fully autonomous vehicle.
Before enabling Autopilot, you must agree to “keep your hands on the steering wheel at all times” and to always “maintain control and responsibility for your vehicle.” Once engaged, Autopilot will also deliver an escalating series of visual and audio warnings, reminding you to place your hands on the wheel if insufficient torque is applied or your vehicle otherwise detects you may not be attentive enough to the road ahead. If you repeatedly ignore these warnings, you will be locked out from using Autopilot during that trip.
You can override any of Autopilot’s features at any time by steering or applying the accelerator at any time.”
It is good that Tesla is rewarding those who learn from their mistakes with this shorter timeframe to lose the strikes. It won’t be needed forever, though, as eventually, the company will solve autonomy. The question is: when?

Elon Musk teases the capabilities of the Tesla Roadster once again

Elon Musk has once again teased the capabilities of the Tesla Roadster, fueling the anticipation that many have for the vehicle, despite it still having no public production or delivery date.
The Roadster is among the most anticipated vehicles in the automotive sector currently, and as Tesla has teased its capabilities, from a lightning-fast 1.1-second 0-60 MPH acceleration to potential hovering with cold-gas thrusters, people are eager to see it.
Although the design seemed to be finalized, there was still more work to be done. Earlier this year, as Tesla was showcasing some of the Roadster’s capabilities to Musk, he stated that it was capable of even more.
This pushed back its production date even further, much to the chagrin of those who have been waiting years for it.
Musk continues to tease us all, and as we sit here waiting hopelessly for it to be revealed, he said today that it is “something special beyond a car.”
The new Roadster is something special beyond a car
— Elon Musk (@elonmusk) September 17, 2025
Musk’s words were in response to a video posted by Tesla China, showing the Roadster in a new promotional video created by a fan.
The Roadster was planned to be released in 2020, but here we are in 2025, and there is still no sign of the vehicle entering production. However, Tesla did say earlier this year that it would host a demo event for the Roadster, where the company would showcase its capabilities.
Lars Moravy said earlier this year:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”
Tesla exec gives big update on Roadster, confirming recent rumor
The delays have been attributed to “radically increased design goals” for the vehicle, which have, without a doubt, improved its capabilities, but at the same time, we just want to know if it’s ever going to come.
Tesla can always make it “better,” but at what point do you say, “Okay, it’s time to show this thing off.” They could always build another, even more capable supercar in the next ten years.
