Tesla’s million mile battery: Veteran auto’s ‘fake it till you make it’ strategy is perfectly fine
It is no secret that Tesla is actively pursuing a million-mile battery. With such an innovation, Tesla hopes to make its electric cars outlast gasoline-powered vehicles several times over, while ensuring that its energy storage devices are capable of lasting literal decades while being actively deployed. But if recent news is any indication, it appears that Tesla is not the only company that is closing in on a million-mile battery.
During a recent online investor conference, GM Executive Vice President Doug Parks stated that the veteran American automaker is also working on a million mile battery solution. Beyond this, Parks suggested that GM is “almost there” in developing a battery that’s far above the Ultium batteries that were announced last March. Unfortunately, the GM executive did not specify a solid timeline for the introduction of its own million mile battery, only stating that multiple teams were working on it.
GM’s rather sudden announcement of its million-mile battery echoes the company’s overall strategy with its electric vehicle program. Back in March, the automaker unveiled a sweeping electric vehicle strategy that will involve $20 billion in investments and about 20 EVs for practically every market. But despite the grandiose plans and announcements, the veteran automaker did not really disclose a lot of concrete details about its EV push, such as pricing, specifications, and timing.
GM’s approach to electric vehicles almost seems like a “fake it till you make it” strategy. Back in March, there was a lot of talk about Tesla’s upcoming Battery and Powertrain Day, which was speculated to involve discussions and announcements about the company’s next-generation of electric vehicles and energy solutions. GM’s “EV Day” seemed to be a response to this. In the same light, the previous weeks have involved updates about the impending release of Tesla’s million mile battery, an innovation that is apparently “almost there” in GM.
While this may at times feel like veteran automakers like GM are simply following Tesla’s EV playbook, it must be noted that every step made by legacy carmakers towards electric vehicles is a step towards the wider adoption of sustainable transport. Thus, despite the fact that GM’s EV strategies today are more smoke and mirrors and concept vehicles, the American automaker’s focus on electric cars is still admirable. This is a pretty big point for GM, considering that it is the very company that practically stopped the first coming of the modern electric car with its controversial cancellation of the EV1.
Besides, it is difficult to deny that legacy automakers such as GM are making an effort towards electrification now. Despite the fact that leaked production plans accessed by Reuters indicated that GM and Ford only intend to produce 320,000 EVs in 2026 for the North American market, the company is still investing heavily in EVs. For its Ultium batteries, for example, GM has stated that it is working with Korean firm LG Chem to find ways to reduce costs and improve overall performance. Adam Kwiatkowski, executive chief engineer of GM’s electric propulsion systems, noted that the automaker and LG Chem are also looking at investments in mines, hedging metals prices, and potential partnerships with metal refiners.
The next few years will definitely be one for the record books, as Tesla enters its next phase with its million mile battery and Plaid powertrain, and legacy automakers such as GM take a serious stance on electric vehicles. It’s easy to forget, after all, that less than a decade ago, the pervading narrative in the auto industry was that electric cars are still intended to be stuck as niche products, glorified golf cars for the wealthy and not much more.
The landscape today is very different, and there’s no bigger symbol of this change than GM’s own Hummer EV, a vehicle that’s the spiritual successor of the gas-guzzling monster SUV that pretty much killed the EV1. Other vehicles like the Tesla Cybertruck, which is expected to break the stereotypes of EVs as vehicles that cannot be used for real work and utility, further shows the steady trend forward for electric cars.
Tesla is a leader in the electric vehicle movement. That much is sure. But the company itself has noted that it cannot transition the world towards sustainability on its own. For true sustainability to happen, other companies, legacy carmakers like GM included, have to go all-in on the EV movement as well. One can only hope that this time, announcements such as GM’s million mile battery initiative are more on the “make it” side than on the “fake it” side.

Tesla has reached a notable benchmark in its autonomous driving program after its Robotaxi fleet surpassed one million miles of unsupervised operation. The company made the announcement during its Cybercab event in Austin on September 3.
Tesla Vice President of AI Ashok Elluswamy told attendees he was happy to report the fleet had achieved one million miles of unsupervised Robotaxi operation as a testament to safety.
The new total marked a sharp increase from the 380,000 unsupervised miles Tesla disclosed during its second-quarter 2026 earnings update in late July.
In roughly six weeks, the company added about 620,000 miles. That acceleration followed Tesla’s decision to remove in-vehicle safety monitors from most of its operations outside the San Francisco Bay Area.

Tesla first launched Robotaxi service in Austin in June 2025 with safety drivers present. It later began fully unsupervised rides and expanded into Dallas, Houston, Miami, Orlando, and Tampa. The San Francisco Bay Area remains the exception, where a safety monitor still rides in the vehicle under California permitting rules.
The company has not released a city-by-city breakdown of the one million unsupervised miles.
The milestone arrived as Tesla began offering public Cybercab rides in Austin. The purpose-built vehicle has no steering wheel or pedals and is designed only for autonomous ride-hailing. Production versions joined the existing fleet of modified Tesla vehicles already operating in the service.
Tesla’s unsupervised mileage is growing at a double-digit weekly rate according to earlier company comments, yet its fleet size remains modest compared with established competitors. Waymo has accumulated more than 200 million fully autonomous rider-only miles. Tesla has described its own unsupervised operations as having recorded zero notable incidents in the period leading up to the July update.
The one-million-mile figure reflects Tesla’s shift from supervised testing to broader driverless service in multiple states. It also highlights the company’s strategy of using both existing Model Y vehicles and the new Cybercab to scale its network.

Whether the rapid recent growth continues will depend on further city expansions, regulatory approvals, and the performance of the purpose-built Cybercab in everyday paid rides. Tesla has not specified how many of the latest miles involved the new vehicle versus the rest of the fleet.
The announcement underscores Tesla’s progress toward a larger robotaxi network while illustrating the remaining gap in total autonomous experience relative to longer-operating rivals.
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.
