Rivian’s self-driving patent application hints at driver monitoring functionality
Rivian’s Associate Director of Self-Driving, Oliver Jeromin, discussed a driver monitoring system that’s part of the company’s full self-driving suite in a recent interview. Thanks to a recently published patent application by the all-electric carmaker, more details about how such a system would work are now available.
The patent application, titled “Occupant Awareness Monitoring for Autonomous Vehicles,” was published on July 25, 2019, under serial number US 2019/0225228. It describes a multi-part system wherein driver activity is interpreted through synced wireless devices either on a smartphone or directly with the vehicle itself. If a driver’s awareness is needed and determined not to be available, the vehicle will take remedial action to ensure a high level of safety.
The five levels of vehicle autonomy defined by the Society for Automotive Engineers (SAE) (and adopted by the U.S. National Highway Traffic Safety Administration) range from level 0 with no automation to level 5 with full automation. Levels 3-5 specifically require that their human driver (or passenger if Level 5) be ready to retake control of the vehicle or respond in some way under specific circumstances. That said, Rivian’s invention described in this application seeks to detect whether the necessary level of readiness is present in the driver.

“The present inventors have recognized the technological problem of a potential need for human intervention in connection with the operation of autonomous automotive vehicles featuring autonomy levels 3, 4, or 5, and have observed a need for a technological solution to monitor the awareness of vehicle occupants,” the application states in the background portion of the description.
The monitoring process is described to work as follows:
- Connect, by vehicle, to wireless device of vehicle occupant.
- Receive, by vehicle, signal from wireless device indicative of activity of the vehicle occupant and processing the signal to determine level of awareness of vehicle occupant.
- Determine whether level of awareness of vehicle occupant satisfies a threshold.
- Generate, by vehicle, alert based upon whether level of awareness of vehicle occupant satisfies threshold.
To accomplish these steps, Rivian proposes in the application to pair electronic devices that can track and provide driver data to the automated driving program, e.g., general smartphones or tablets, finesses trackers, and electronically connected medical devices. If a driver is watching a movie or has vital signs indicating sleep (breathing rate, pulse, etc.), the vehicle would know the driver is not ready to resume control if needed and respond appropriately.
Also described in the patent application are enforcement ideas such as a series of touch screen prompts requiring a response, and in the event of no response, the vehicle would pull over and stop. If an emergency situation were detected via the connected medical devices, the car would pull over and call 911. Along with a fitness tracker, other medical devices suggested for use in the application are glucose monitors, blood oxygen monitors, and breathalyzers.
Driver attentiveness while using self-driving features is already a problem under Level 2 programs where warning prompts are fairly strict about keeping eyes on the road. Tesla, for instance, regularly reminds its customers that Autopilot isn’t a full self-driving system yet and needs complete driver attention. However, as headlines and Tesla crash investigations have indicated, the warning isn’t always heeded.
Rivian’s driver monitoring system certainly sounds like a good step towards increasing safety measures as the carmaker continues to develop its product lines. The proposed syncing of medical devices might run into some resistance on privacy grounds, but the overall payoff that a safe self-driving experience will provide may find cause for compromise. Overall, it’s clear Rivian has safety as a priority as it prepares to enter the automotive arena with the R1T pickup truck and R1S SUV later next year.
A California radiologist who drove his Tesla Model Y off a 250-foot cliff in an attempt to kill his family has had his charges dismissed after doctors say he is “doing well” in a mental health program.
Dharmesh Patel was charged with three counts of attempted murder in connection with a January 2023 crash where he drove his Tesla off a cliff, injuring his wife and two children, aged 7 and 4 at the time.
Patel drove the Tesla off Devil’s Slide in California, an area that is extremely rough to the point that investigators and rescuers expected the worst when arriving at the scene for the first time. Patel supposedly had schizoaffective disorder, according to Deputy District Attorney Dominique Davis.
Shockingly, Patel’s wife, who was in the vehicle, testified that she did not want her husband to be prosecuted, noting that their children missed their father and they wanted him to come back home. Patel’s attorney argued, “not everyone who commits a crime is a criminal.”

A three-day trial in Mental Health Diversion Court ruled in Patel’s favor, which kept him out of jail and instead on house arrest. He was admitted to a Mental Health Diversion Program, which he successfully completed, the Associated Press reported. San Mateo County District Attorney Steve Wagstaffe said the judge was “required by law” to dismiss the charges:
“If the person who’s given mental health diversion follows the treatment plan, there’s nothing that can be done, and at the end of the two years he gets it wiped out of his record.”
Wagstaffe said he has argued, along with other DAs in California, to have attempted murder removed from the list of charges eligible to be dismissed due to mental health diversion programs.
Patel had the charges officially dismissed on Monday; his wife waited for him as he left court and they departed the building together, according to Mercury News. Patel surrendered his California medical license in December.
The crash has been one of the best examples of Tesla’s incredible engineering, which has saved four lives in this particular instance. The car was totalled but kept the four human beings alive and safe, which is something that many referred to as “an absolute miracle.”
A common misconception of anti-EV proponents is that the batteries used in the vehicles are detrimental to the environment and that they cause more waste than they are worth. But a look at Tesla’s battery recycling efforts last year shows the company is doing more than ever to recover materials and give portions of the cells a second life.
Tesla reported a significant milestone in its sustainability efforts last year, with battery recycling volumes rising 20% compared to 2024. According to the company’s 2025 Impact Report, Tesla recycled over 14,000 metric tons of battery material through a combination of in-house processing at its Gigafactories and collaborations with third-party recycling partners.
Tesla: “In 2025, we recycled over 14,000 metric tons of battery material through a combination of in-house processing and through our network of recycling partners.”

This amount of recovered material is equivalent to the resources needed to produce approximately 46,000 long-range battery packs. The increase reflects growing operational scale as Tesla’s global vehicle fleet expands and more batteries reach end-of-life or manufacturing scrap becomes available for processing.
Tesla and Battery Recycling
Battery recycling forms a core part of Tesla’s circular economy strategy. The company designs its batteries for longevity, often exceeding 200,000 miles of driving, and prioritizes repairs, remanufacturing, and second-life applications before full recycling.
Once packs are decommissioned, Tesla ensures 100% are recycled with no materials sent to landfills. This approach recovers critical metals including lithium, nickel, cobalt, and copper, which can be refined and reused in new battery production.
Tesla has advanced hydrometallurgical recycling processes capable of achieving recovery rates up to 98% for key battery metals. These methods are more efficient and environmentally friendly than traditional pyrometallurgical techniques, reducing energy use and enabling higher-purity materials suitable for direct reintegration into battery manufacturing.

In-house capabilities are supplemented by a network of specialized partners, creating a robust system that handles both production scrap and end-of-life packs.
The environmental and economic benefits are substantial. Recycling reduces reliance on virgin mining, lowers the carbon footprint associated with raw material extraction and processing, and helps stabilize supply chains for critical minerals amid rising global EV demand. As millions of Tesla vehicles age, the volume of recyclable material is expected to grow significantly in the coming years.
This 20% year-over-year growth demonstrates the effectiveness of Tesla’s investments in recycling infrastructure and technology. It positions the company as a leader in addressing one of the automotive industry’s major sustainability challenges. Continued innovation in battery design for easier disassembly and higher recyclability will further enhance these efforts.
Overall, Tesla’s progress in 2025 highlights how scaling recycling operations supports both environmental goals and long-term business resilience in the transition to electric mobility. As the EV market matures, such closed-loop systems will become increasingly vital for sustainable growth.
Tesla has spent years trying to engineer its way out of the automotive paint shop, one of the most expensive, space-consuming, and environmentally costly steps in vehicle manufacturing. With the Cybercab, Tesla confirmed on X this week that a new reaction injection molding process will embed color directly into the panel itself during production.
“Our new reaction injection molding (RIM) process shrinks Cybercab paint cycles from hours to minutes. This cuts those parts’ manufacturing and supply chain emissions by 35% and eliminating 100% of paint volatile organic compounds (VOCs) emitted in traditional paint methods.” noted Tesla.
While the RIM process isn’t necessarily new and has existed since the 1960s, what makes Tesla’s application notable is how it is being used specifically for exterior body panels that traditionally required a separate paint process after forming.
Tesla’s RIM approach integrates the color directly into the panel material during the molding process itself. The pigment is part of the polymer mix injected into the mold, meaning the panel comes out of the mold already colored, with no separate paint application required. The clear coat or protective layer can be applied at the mold stage or through a much faster post-process than traditional multi-stage painting. Tesla claims this compresses what was a multi-hour paint cycle into minutes per panel.
Tesla’s obsession with killing the paint shop is one of the most consistent threads running through the company’s manufacturing philosophy going back years. As far back as 2018, Musk was trimming paint color options to simplify production, tweeting at the time: “Moving 2 of 7 Tesla colors off menu on Wednesday to simplify manufacturing.” Two years later, in a 2020 Automotive News interview, Musk laid out his broader vision, saying he believed Tesla factories could one day be 1,000 times more efficient than conventional plants, and pointing to the paint shop as one of the biggest sources of waste, cost, and complexity. The Cybertruck was the most extreme expression of that thinking. Tesla chose an unpainted stainless steel exterior partly because it would eliminate the need for a $200 million paint facility at Gigafactory Texas. The stainless approach proved harder and more expensive than anticipated, but the underlying ambition never changed. The Cybercab is what happens when that same ambition meets a manufacturing process that delivers on it.
