Former Tesla 4680 battery cell production engineer James Herbermann has been named Vice President of Manufacturing at the American Battery Factory (ABF).
“James brings to American Battery Factory incredible perspective and front row experiences in evolving battery cell technology and is the perfect complement to our team as we begin our journey to develop a domestic battery manufacturing ecosystem that will make energy independence and renewable energy a reality for the United States,” ABF CEO and President Paul Charles said. “As we lay the foundation for our factory network, I am confident James’ cross-functional leadership will not only enhance the efficiency of ABF’s modular approach to manufacturing, but it will also propel our unwavering quest to develop the longest-lasting LFP prismatic battery cells on the market.”
James Herbermann, formerly with Tesla, joins American Battery Factory as its new Vice President of Manufacturing.
ABF is working to develop the United States’ first network of Lithium-Iron Phosphate, or LFP, battery cell gigafactories. The LFP cell is a major part of many automakers’ plans for future electric vehicles as more cell chemistries are being utilized to combat excessive demand. Tesla, for example, started transitioning its Standard Range trim levels to LFP batteries last year. The automaker confirmed that it would utilize the cell chemistry in lower range vehicle as they are less expensive and have longer lifespans. They do have their disadvantages, especially in terms of energy density, which means less power and range with EVs that utilize these packs. They are also more likely to be affected by adverse weather conditions, especially in colder climates.
CEO Elon Musk has said in the past that LFP packs want to be charged to 100 percent, as opposed to nickel-based packs that prefer a 90 percent state of charge.
Tesla is just one of the companies working to use LFP cells. Rivian, Ford, and Volkswagen are also utilizing the cell chemistry for some of their vehicles. Therefore, the need to produce more cells to provide automakers and customers with suitable options is definitely a work in progress.

ABF is working to eliminate LFP shortages with a series of production plants across the U.S., and the company is looking for Herbermann to lead and support all aspects of its manufacturing and production operations. Prior to ABF, Herbermann worked at Tesla to lead the development and scaling of its new battery electrode processes in Austin from the pilot program to a full-scale production process. He was a direct piece of Tesla’s commercialization of the 4680 cells, which has been installed in early builds of the Model Y from the new Austin factory. Additionally, Herbermann has developed “novel Sodium Titanium Phosphate; F1 racing Li-Ion cells; Aquion Hybrid Ion (AHI®); Duracell Ultra®; Comfort Plus® modular carpet tiles; and ZIP Wall® sheathing,” a press release from ABF said.
“I am inspired by ABF’s mission to develop a domestic supply chain for LFP batteries, especially in light of the pandemic’s crippling effect on availability and our country’s glaring void in battery cell manufacturing,” Herbermann said about his new role. “With its strategic approach of constructing a network of modular rapid construction factories near or onsite at pack integrators and energy solution providers, ABF is on track to solve one of the planet’s most pressing energy needs. I look forward to being a part of this impactful work.”

Tesla just upgraded its headlights through a software update, making them even better without any physical or hardware upgrade.
Tesla’s latest software update is quietly improving nighttime driving for a small number of owners. Version 2026.38 includes a new capability called Dynamic Headlight Leveling.
The feature automatically adjusts the aim of the low beams in response to driving conditions and nearby traffic, with the goal of giving the driver more usable light on the road while reducing glare for oncoming vehicles and traffic ahead.

Model 3 gets Dynamic Headlight Leveling — low beams auto-aim around traffic for max visibility, less glare. Model 3 / Y (AMD HW3) also pick up sharper Tesla visuals + an enhanced park scene on the center display.

Unlike Tesla’s matrix high-beam system, which selectively dims individual LED segments to create shadows around other cars, Dynamic Headlight Leveling physically tilts the low-beam projectors. Internal motors respond to changes in vehicle pitch.
When the car accelerates hard, climbs a steep grade, or carries extra weight in the rear, the headlights can otherwise point higher than intended. The software counters that movement in real time so the beam stays aimed at the road surface rather than into the eyes of other drivers.
Early indications reveal the update is reaching a limited set of vehicles, including certain Model 3 and Cybertruck examples in the United States and the United Arab Emirates. The rollout does not appear tied to a single hardware revision, and Tesla has not published a broader schedule. It is simply a common waiting game until your car receives it.
The change arrives against a backdrop of wider complaints about headlight glare. Some earlier Model 3 and Model Y vehicles were the subject of an NHTSA recall related to excessive low-beam glare; the software adjustment offers a potential mitigation for cars equipped with the necessary leveling hardware. It does not replace adaptive high beams where those are already available, nor does it alter the basic low-beam pattern itself.
Instead, it keeps an existing beam pointed where it is most useful.
For drivers who have received the update, the system requires no new settings or user input. The headlights simply respond as road conditions and traffic change. As the feature reaches more vehicles, it adds another example of Tesla using over-the-air software to refine existing hardware rather than waiting for a new model year. Nighttime visibility and reduced glare for others are the practical results owners are expected to notice first.

Tesla teases “Halloween Mode” update with Optimus rising from a graveyard
Tesla’s Halloween teaser hides a covered vehicle and an Optimus hand rising from the ground.
Tesla has started teasing a Halloween software update for its vehicles, with a short clip on X that reads, “Halloween is coming.” The clip opens on a glowing pumpkin before pulling back to the car’s center touchscreen, where the usual parked visualization has been replaced by a graveyard scene, and the vehicle draped with a white sheet so it reads as a cartoon ghost.

The second detail is a robotic hand clawing its way out of the dirt like a zombie, which looks to be the hand of Tesla’s latest Optimus V3 humanoid robot. While Tesla still has not formally shown Optimus Gen 3 walking around in service, renders pulled from Tesla’s Android app last month gave the clearest look yet, including far more refined hands that Tesla has said carry 22 degrees of freedom. The hand has been the hardest part of the program. Musk has called it the majority of the robot’s engineering difficulty, and Tesla’s patents describe a design driven by tendons with the actuators moved into the forearm.

Optimus also has a Halloween track record. Last October the robot handed out candy in Times Square, and a costumed “zombie” Optimus shuffled around the Tesla Diner in Los Angeles on Halloween night.
On the software side, Tesla’s 2025 Holiday Update expanded Santa Mode with a Santa sleigh, snowmen, snow effects, and a festive lock chime, so it wouldn’t be too far fetched if we saw something similar but themed for a Halloween Mode.
Tesla Full Self-Driving is set to receive improvements to address its two biggest issues, according to a company engineer.
Director of Engineering at Tesla AI, Phil Duan, revealed in a post on X that improvements to both pothole avoidance and navigation “are coming,’ something we have heard many times in the past. However, there are a few things that seem to hint that things might be different this time around.
Improvements on both are coming.

Pothole avoidance, navigation, speed control, and left lane camping are some of the most prevalent and frequently mentioned shortcomings of the Full Self-Driving suite. These are a few of the biggest issues that have kept Tesla Full Self-Driving as a Supervised suite, meaning drivers must remain attentive during operation.
Pothole Avoidance
Pothole avoidance was first mentioned as an “Upcoming Improvement” with the Tesla Full Self-Driving v14.3 update back in early April of this year. It was listed alongside “Expand reasoning to all behaviors beyond destination handling.”
It’s been six months since we first saw pothole avoidance explicitly mentioned, and it has not moved beyond that and joined the main release notes yet.
Tesla has not shed any light on why pothole avoidance has been such an issue for it to solve, but it also has issues identifying large bumps much of the time, so its modeling of sudden changes in road conditions is likely pretty weak at this particular point. I’ve had more issues with large bumps than potholes, personally, but both are issues that need to be resolved.
This is that big bounce that I mentioned in the quoted post.
It’s just a tad too drastic to take at the speed FSD wants to go over it. You can see me quickly swipe down into Sloth, but I intervened. https://t.co/K20PK9ysBg pic.twitter.com/81Oc82ZJcZ

It makes sense that things might be pretty close to being released to the public, as we are going on such an extensive period of time between it being mentioned and it actually being deployed.
Navigation
Navigation is likely the most painful part of using Full Self-Driving, as it routinely takes strange routes, has trouble with local rules (like Except Right Turn Stop Signs in Pennsylvania), and sometimes does not realize that maneuvers it is suggesting are against the law. Turning out of my neighborhood, you cannot turn left, yet my Model Y still suggests it roughly 70 percent of the time when I’m leaving.
However, Tesla might be close to a breakthrough on this. With the Summer Update, Tesla added “Preferred Routes” alongside “Automatic Navigation.”
Preferred Routes prioritized roads that the driver had actually taken before, instead of always defaulting to what the vehicle believes is the most efficient path. This has already solved many of my issues. Formerly, I would turn off the Online Routing setting, and that would eliminate most of my complaints with routing, but then you lose out later on the Live Traffic Visualization.
Tesla’s Navigation has improved tremendously thanks to the Preferred Routes release with the Summer Update, but it still could use some polishing, as it still suggests strange routes from time to time, and it also has a lot of issues getting out of a parking lot. I find that those truly confuse FSD sometimes.
