Tesla CEO Elon Musk promised a “giant contract” to a nickel supplier during the Q2 2020 Earnings Call. The problem is that the company will have trouble finding an efficient and environmentally-friendly nickel mine, and it could prove to be Tesla’s biggest challenge yet.
Nickel is a crucial metal in electric vehicle batteries because it can increase energy density and provide cars with more range. Musk stated during the Earnings Call that nickel-based cells are essential for the development of larger vehicles, like the Tesla Semi, for example. “Where every unit of mass that you add in battery pack, you have to subtract in cargo,” he said. “So it’s very important to have a mass efficient and long-range pack.”
Nickel-based cells would give Tesla an advantage in electric vehicle range, a category where the company already leads by a sizeable margin. However, with new vehicles on the way, cells have to be adjusted to work with specific workloads. The Semi is an excellent example of this.
Nickel could replace cobalt in Tesla’s current battery cells. Cobalt, a controversial element on its own, is responsible for stabilizing the cell and has been effective in increasing the safety of the high-energy batteries that Tesla has used. However, the mining process of cobalt is questionable, and mines which can obtain it likely are using child labor, which is highly illegal. It also is not environmentally-friendly to mine.
Tesla has taken extra steps to ensure that its cobalt suppliers are treating their workers humanely through a series of due diligence checks. Third-party companies complete random visits to these mines a few times a year to ensure that the cobalt Tesla is using in its batteries is humanely obtained.
The problem is: Nickel mining isn’t much different. Although it would be advantageous, safer, and provide more range for Tesla’s vehicles, it is tough to find nickel that is environmentally-friendly and responsibly mines. The largest nickel sources are in Indonesia, where millions of tonnes of waste are dumped into the sea, polluting coral reefs and damaging the homes of turtles.
Analysts believe that Indonesian miners will provide nearly all of the growth of nickel supplies over the next decade. With electric cars becoming more popular, batteries will be a large part of the surge in demand for the metal. Still, it is also used in everyday products, like stainless steel appliances, Financial Times says.
Other countries, like Canada and Australia, have nickel mines, but Indonesia is highly concentrated with it.
Steven Brown, a consultant and former employee at nickel mining company Vale, says that it could be challenging for customers who are environmentally-conscious to want products that contain the metal after hearing how some entities dispose of it.
“It could undermine the entire proposition of trying to sell a consumer a product that is environmentally friendly, if you have this back story,” he said.
Even though other countries have nickel available, the increased demand for EVs will require large automakers, like Tesla, to eventually have to source some of the metal from Indonesia. “At some point, it will happen where they can’t avoid Indonesian nickel,” Brown added.
Luckily, Tesla requires its sources to go through due diligence processes, and it is unlikely the company will steer away from them to obtain nickel. Of course, Tesla will benefit from having more nickel, but it has to be sourced responsibly for the company even to consider using it.
On top of that, nickel is the second most expensive metal in EV batteries. It only trails cobalt, which Tesla has worked intensively to get away from because of its environmental and humanitarian impact.
“We use very little cobalt in our system already, and that’s — that may to zero along, so it’s basically about nickel,” Musk said.
There is a delicate balance between positive environmental impact after EVs hit the road and the harmful impact sourcing some of the metals have. However, the automakers do not assume any of the responsibility for the mining companies’ process of getting rid of waste. But it is their responsibility to choose a company that decides to handle the ridding of environmentally-harming materials responsibly.
Tesla has made it a point to choose companies that share their mission for sustainability because the automaker realizes that building an electric car starts with sourcing the materials. If the materials are not responsibly obtained, then the EV isn’t as Earth-friendly as it could be.
Pius Ginting, an environmental activist, summed it up perfectly: “The net result is we have clean air in our cities — but then we destroy a rich biodiversity area.”
Tesla AI lead Ashok Elluswamy said this week that 24-hour Robotaxi service is close. Replying on X to a rider who wanted Cybercab trips all night, he wrote that the capability would arrive “next month or so” once “the next tech to merge on the v15 plan” is ready.
The comment landed on September 4, one day after Tesla opened public Cybercab rides in Austin. It is the clearest near-term timeline yet for overnight unsupervised operation. Tesla’s paid Robotaxi network currently runs from 6 a.m. to 10 p.m. seven days a week across Austin, Dallas, Houston, Miami, Orlando, and Tampa.
next month or so. the next tech to merge on the v15 plan will enable it.

That 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.
Elluswamy did not name the specific feature or say whether the change would apply first to purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list. The link to Full Self-Driving v15 is nevertheless significant.
Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.
By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states with what the company called an impeccable safety record and no notable incidents caused by the vehicles themselves. Tesla has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.
Overnight service would test that claim in lower-light conditions and would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.
Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale: Tesla has held back mass expansion until more of the v15 stack is merged, citing the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.
If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets.
That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.
It may also engage if we…

The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.
