Rivian patent hints at real-time brake wear monitoring system using driver profiles
Rivian’s attention to detail on its all-electric vehicles is laudable, and a recent patent application by the outdoor adventure company for monitoring brake wear continues that theme. In an application titled “Methods, Systems, and Media for Non-Contact Brake Pad Wear Determination”, a method of estimating the wear on individual breaks via computer algorithms is described. Once calculated, the information is then made available to drivers for planning purposes via the infotainment screen on the R1T pickup truck and R1S SUV. The application published on August 1, 2019 under US Patent Publication No. 2019/0234475.
The background of Rivian’s application stated the following reasons why the invention is needed:
“Current approaches for determining brake pad wear…tend to merely indicate when brake pads are fully worn, for example, using a brake pad indicator that causes the brakes to squeal when the indicator contacts the brake disc or that causes an indication on a dashboard of the vehicle to be presented. It may be useful for a driver to know a current wear condition of the brake pads before the brake pads are fully worn, for example, to plan for vehicle maintenance. However, it can be difficult to determine a current wear of the brake pads.”
While not an official reason listed on the patent, one could also assume brake squealing as an annoying sound in itself would also merit the invention’s usefulness as a reliable preventative.

Overall, Rivian’s application calculates the amount of wear on its vehicles’ brakes by comparing data points gathered from two braking events. The amount of pressure applied plus the distance traveled at two different intervals is collected, then compared to a brake database, and an estimate of the mileage left before a change is needed is provided to the driver. The calculation can also include the driver’s braking history to more accurately reflect the mileage. In other words, if you’re a bit rough on the brake pedal, Rivian’s software will take that into account and probably shorten the mileage you have left before needing replacement parts compared to someone that drives…differently. Here’s the formal language for this ability:
-->“In some embodiments, the method further comprises associating a braking profile with an operator of the vehicle, wherein the indication of the wear amount of the brake pad includes a number of miles until the brake pad requires replacement that is estimated based on the associated braking profile.”
The method described in the claims of the application that calculate the wear on the brakes indicates a process initiated by the driver, i.e., the driver initiates a brake wear test on the center touchscreen and uses the brakes at two intervals as instructed by the vehicle’s computer to determine the wear percentage. However, the description of the application indicates that the brake testing can also happen in real-time during normal operation. The formal language for this reads as follows:
“…In some embodiments, [the testing] process…can receive a group of brake caliper measurements and corresponding brake pedal travel distances…during application of the brake pedal during normal operation of the vehicle…Additionally, in some such embodiments, [the testing] process can present indications of brake pad wear at any suitable time, such as a next time the vehicle is turned on, and/or at any other suitable time.”
This application is yet the latest nod towards Rivian’s development of a comfortable and luxury driving experience for its vehicle owners. The car maker’s branding as an outdoor electric adventure company really seems to have embraced its mission to get people outside exploring more by making the experience as convenient as possible. Whether it’s ample storage capacity, swapping out cargo modules, extending battery range with a digital jerry can, a portable kitchen built specifically for the R1T pickup truck, or now, being able to easily plan ahead for basic vehicle maintenance by checking a screen, Rivian is continuing its march against barriers to enjoying nature anywhere.
There’s a new phrase that seems to be developing based off of an old one about willpower: “Where there’s a Rivian, there’s a way.”

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.

Elon Musk shares SpaceX’s directive that destroys a prevalent media narrative
Musk’s comments followed Starlink’s initiatives for people affected by severe flooding in Indonesia and Cyclone Ditwah in Sri Lanka.
Elon Musk recently shared SpaceX’s standing policy to offer free Starlink service during natural disasters worldwide, highlighting the company’s commitment to pursue aid over profit during times of need.
Musk’s comments followed Starlink’s initiatives for people affected by severe flooding in Indonesia and Cyclone Ditwah in Sri Lanka.
Starlink activates free service in Indonesia and Sri Lanka
Starlink recently announced free service for those impacted by severe flooding in Indonesia’s Sumatra region, partnering with the government to deploy terminals rapidly to the hardest-hit areas. The offer extends to new and existing customers through December, restoring connectivity in zones where traditional networks have failed due to infrastructure damage.
Musk quoted the post on X, writing, “SpaceX standard policy is to make Starlink free whenever there is a natural disaster somewhere in the world. It would not be right to profit from misfortune.”
Starlink extended the same relief to Sri Lanka amid Cyclone Ditwah, coordinating with local authorities for additional support. The cyclone battered the island nation with heavy rains and winds, disrupting communications for thousands. Free access also lasts until year-end, emphasizing Starlink’s role in bridging gaps during crises.
-->“For those affected by the severe flooding in Indonesia and Sri Lanka in the aftermath of Cyclone Ditwah, Starlink is providing free service to new and existing customers through the end of December 2025. We’re also working with the Indonesian government to rapidly deploy terminals and restore connectivity to the hardest-hit areas on Sumatra, as well as with the Sri Lankan government to provide additional assistance,” Starlink wrote in a post on its official website.
Musk’s companies routinely provide aid
Musk’s firms have a track record of providing critical support in crises, often without fanfare, challenging portrayals of him as a comic book villain intent on enriching himself on the backs of a suffering populace. In January 2024 alone, Tesla opened Superchargers for free in Japan’s Hokuriku region after a magnitude 7.6 earthquake killed at least 55 and injured hundreds.
Similar efforts include Starlink deployments for the 2023 Maui wildfires, 2024 Hurricane Helene in North Carolina, and floods in Texas, where the service was used to help facilitate emergency coordination. These actions, which total millions in waived fees and logistics, demonstrate a proactive ethos among Musk’s companies, with Musk noting in past interviews that such aid stems from engineering solutions over optics.
The initiatives also provide a direct rebuttal of Musk’s characterization on mainstream media, which tends to lean negatively. This has become much more notable in recent years as Musk adopted more conservative policies. These negative sentiments came to a head earlier this year when Tesla stores, vehicles, and even some owners, were attacked during waves of anti-Tesla protests.

The event featured interactive demos, a light show with the full Tesla lineup, and announcements including FSD Supervised’s planned rollout to Cybertruck by the end of 2025.
Tesla Korea handed over its first 30 Cybertrucks to owners on Thursday during a ceremonial event at the Cultural Reserve Base in Seoul, marking the all-electric pickup truck’s official debut outside North America.
The event featured interactive demos, a light show with the full Tesla lineup, and announcements including FSD Supervised’s planned rollout to Cybertruck by the end of 2025.
A historic delivery event
The November 27 event transformed a former oil reserve warehouse into a symbolic launchpad for electric mobility. Attended by 30 new owners, the event included hands-on activities such as hammer-strike durability tests, accessory sales, a lucky draw, and group photos. It culminated in a synchronized light show featuring the 30 Cybertrucks alongside Model S, Model 3, Model X, and Model Y vehicles, which drew cheers from attendees.
Yvonne Chan, Tesla APAC Regional Director, joined as a special guest to celebrate the delivery milestone. Tesla Korea President Seo Young-deuk was also in attendance, and shared his optimism for the company’s momentum in the country.
“Korea is currently the third-largest market for Tesla sales worldwide, and this year, for the first time, it has achieved the No. 1 spot in imported car brand sales volume, Tesla Korea is growing at an incredibly rapid pace,” he said. “To repay this love from our customers, Tesla plans to continue investing in the Korean market and enhancing the customer experience.”
-->FSD Supervised launches in Korea
Seo announced the official introduction of Full Self-Driving (Supervised) in Korea, with Cybertrucks slated for inclusion by the end of 2025, which promoted applause from the event’s attendees. With even the Cybertruck expected to receive FSD this year, Tesla Korea’s fleet could very well become the country’s most advanced vehicles overnight.
Infrastructure growth remains a priority to support Tesla Korea’s expanding fleet. Tesla Korea’s Supercharger network currently includes 166 sites with 1,133 stalls, with V4 units planned for nationwide highway rest areas to boost long-distance travel. The company also operates seven stores and 15 service centers, though plans are underway to double both by 2027. A new store in Incheon’s Songdo district is scheduled to open by December 2025, enhancing accessibility for western Seoul-area customers.
Seo concluded, “Through all-encompassing investments spanning products, charging infrastructure, and service networks, Tesla Korea will deliver the most refined electric vehicle experience to Korean customers.”
