A carbon-free future "will require many millions of batteries, both to drive electric vehicles and to store wind and solar power on the grid," reports IEEE Spectrum. Unfortunately, today's battery chemistries "mostly rely on lithium — a metal that could soon face a global supply crunch." Recently, Rystad Energy projected a "serious lithium supply deficit" in 2027 as mining capacity lags behind the EV boom. The mismatch could effectively delay the production of around 3.3 million battery-powered passenger cars that year, according to the research firm. Without new mining projects, delays could swell to the equivalent of 20 million cars in 2030. Battery-powered buses, trucks, ships, and grid storage systems will also feel the squeeze... [T]he solution isn't as simple as mining more hard rock — called spodumene — or tapping more underground brine deposits to extract lithium. That's because most of the better, easier-to-exploit reserves are already spoken for in Australia (for hard rock) and in Chile and Argentina (for brine). To drastically scale capacity, producers will also need to exploit the world's "marginal" resources, which are costlier and more energy-intensive to develop than conventional counterparts...

Concerns about supply constraints are driving innovation in the lithium industry. A handful of projects in North America and Europe are piloting and testing "direct lithium extraction," an umbrella term for technologies that, generally speaking, use electricity and chemical processes to isolate and extract concentrated lithium... In southwestern Germany, Vulcan Energy is extracting lithium from geothermal springs that bubble thousands of meters below the Rhine river. The startup began operating its first pilot plant in mid-April. Vulcan said it could be extracting 15,000 metric tons of lithium hydroxide — a compound used in battery cathodes — per year. In southern California, Controlled Thermal Resources is developing a geothermal power plant and lithium extraction facility at the Salton Sea. The company said a pilot facility will start producing 20,000 metric tons per year of lithium hydroxide, also by 2024.

Another way to boost lithium supplies is to recover the metal from spent batteries, of which there is already ample supply. Today, less than 5 percent of all spent lithium-ion batteries are recycled, in large part because the packs are difficult and expensive to dismantle. Many batteries now end up in landfills, leaching chemicals into the environment and wasting usable materials. But Sophie Lu, the head of metals and mining for BloombergNEF, said the industry is likely to ramp up recycling after 2028, when the supply deficit kicks in. Developers are already starting to build new facilities, including a $175 million plant in Rochester, N.Y. When completed, it will be North America's largest recycling plant for lithium-ion batteries.
The Economic Times also argues that electric cars and renewable energy "may not be as green as they appear. Production of raw materials like lithium, cobalt and nickel that are essential to these technologies are often ruinous to land, water, wildlife and people.

"That environmental toll has often been overlooked in part because there is a race underway among the United States, China, Europe and other major powers. Echoing past contests and wars over gold and oil, governments are fighting for supremacy over minerals that could help countries achieve economic and technological dominance for decades to come."

Slashdot reader ytene writes: As reported by The Intercept, U.S. Customs and Border Protection have just spent $456,063 for a package of technology specifically designed to access smartphone data via a motor vehicle. From the article:

"...part of the draw of vacuuming data out of cars is that so many drivers are oblivious to the fact that their cars are generating so much data in the first place, often including extremely sensitive information inadvertently synced from smartphones."

This data can include "Recent destinations, favorite locations, call logs, contact lists, SMS messages, emails, pictures, videos, social media feeds, and the navigation history of everywhere the vehicle has been, when and where a vehicle's lights are turned on, and which doors are opened and closed at specific locations" as well as "gear shifts, odometer reads, ignition cycles, speed logs, and more. This car-based surveillance, in other words, goes many miles beyond the car itself."

Perhaps the most remarkable claim, however, was, "We had a Ford Explorer we pulled the system out, and we recovered 70 phones that had been connected to it. All of their call logs, their contacts and their SMS."

Mohammad Tajsar, an attorney with the American Civil Liberties Union (ACLU), is quoted as saying, "Whenever we have surveillance technology that's deeply invasive, we are disturbed," he said. "When it's in the hands of an agency that's consistently refused any kind of attempt at basic accountability, reform, or oversight, then it's Defcon 1."

boudie2 writes: According to his own employees, Elon Musk has been exaggerating the capabilities of Tesla's Autopilot system. Documents obtained from the California Department of Motor Vehicles show that despite Musk's tweets to the contrary, "Elon's tweet does not match engineering reality per CJ. Tesla is at Level 2 currently." CJ Moore is the company's director of Autopilot software. "Level 2 technology refers to a semi-automated driving system, which requires supervision by a human driver," reports The Verge. "Tesla is unlikely to achieve Level 5 (L5) autonomy, in which its cars can drive themselves anywhere, under any conditions, without any human supervision, by the end of 2021, Tesla representatives told the DMV.

schwit1 shares a report from IEEE Spectrum, written by Evan Ackerman: A few weeks ago, the CTO of Cruise tweeted an example of one of their AVs demonstrating a safety behavior where it moves over to make room for a cyclist. What's interesting about this behavior, though, is that the AV does this for cyclists approaching rapidly from behind the vehicle, something a human is far less likely to notice, much less react to. A neat trick -- but what does it mean, and what's next? In the video [here], as the cyclist approaches from the rear right side at a pretty good clip, you can see the autonomous vehicle pull to the left a little bit, increasing the amount of space that the cyclist can use to pass on the right.

One important question that we're not really going to tackle here is whether this is even a good idea in the first place, since (as a cyclist) I'd personally prefer that cars be predictable rather than sometimes doing weirdly nice things that I might not be prepared for. But that's one of the things that makes cyclists tricky: we're unpredictable. And for AVs, dealing with unpredictable things is notoriously problematic. Cruise's approach to this, explains Rashed Haq, VP of Robotics at Cruise, is to try to give their autonomous system some idea of how unpredictable cyclists can be, and then plan its actions accordingly. Cruise has collected millions of miles of real-world data from its sensorized vehicles that include cyclists doing all sorts of things. And their system has built up a model of how certain it can be that when it sees a cyclist, it can accurately predict what that cyclist is going to do next.

Essentially, based on its understanding of the unpredictability of cyclists, the Cruise AV determined that the probability of a safe interaction is improved when it gives cyclists more space, so that's what it tries to do whenever possible. This behavior illustrates some of the critical differences between autonomous and human-driven vehicles. Humans drive around with relatively limited situational awareness and deal with things like uncertainty primarily on a subconscious level. AVs, on the other hand, are constantly predicting the future in very explicit ways. Humans tend to have the edge when something unusual happens, because we're able to instantly apply a lifetime's worth of common-sense knowledge about the world to our decision-making process. Meanwhile, AVs are always considering the safest next course of action across the entire space that they're able to predict.

General Motors CEO Mary Barra expects the automaker to offer self-driving vehicles to consumers later this decade. CNBC reports: "Later in the decade, I believe, and there's a lot to still unfold, but I believe we'll have personal autonomous vehicles," she told investors Wednesday during the company's first-quarter earnings call. She did not specifically say GM would sell such vehicles directly to consumers. It could lease them or offer customers a subscription service like it did previously for Cadillac vehicles.

Barra's comments come after GM showcased a personal autonomous vehicle concept car for its Cadillac brand in January. The vehicle was based on the Origin, an autonomous shuttle from its majority-owned subsidiary Cruise. GM has a two-pronged approach regarding such systems. Cruise is leading development of fully autonomous vehicles, while the automaker expands its advanced driver-assist Super Cruise system to 22 vehicles by 2023. Barra said the goal for Super Cruise is to eventually offer hands-free driving in 95% of driving conditions. "Both paths are very important because the technology we put on vehicles today, I think makes them safer and delights the customers, and is going to give us an opportunity for subscription revenue," she said Wednesday. "And then the ultimate work that we're doing at Cruise that is full autonomous really opens up more possibilities than I think we can online today."

wiredmikey shares a report from SecurityWeek: Security researchers have shown how a Tesla -- and possibly other cars -- can be hacked remotely without any user interaction from a drone. This was the result of research conducted last year by Ralf-Philipp Weinmann of Kunnamon and Benedikt Schmotzle of Comsecuris. The attack, dubbed TBONE, involves exploitation of two vulnerabilities affecting ConnMan, an internet connection manager for embedded devices. A hacker who exploits the vulnerabilities can perform any task that a regular user could from the infotainment system. That includes opening doors, changing seat positions, playing music, controlling the air conditioning, and modifying steering and acceleration modes. They showed how an attacker could use a drone to launch an attack via Wi-Fi to hack a parked car and open its doors from a distance of up to 100 meters (roughly 300 feet). They claimed the exploit worked against Tesla S, 3, X and Y models. "Tesla patched the vulnerabilities with an update pushed out in October 2020, and it has reportedly stopped using ConnMan," the report notes. Since the ConnMan component is widely used in the automotive industry, similar attacks could be launched against other vehicles.

An anonymous reader quotes a report from New Atlas: A fascinating new study from a team of US researchers has used machine learning techniques to develop algorithms that can analyze naturalistic driving data and detect mild cognitive impairment and dementia in a driver. The work is still in the preliminary stages, however, the researchers claim it could be possible in the future to detect early signs of dementia using either a smartphone app or devices incorporated into car software systems. The research utilized data from a novel long-term study called LongROAD (The Longitudinal Research on Aging Drivers), which tracked nearly 3,000 older drivers for up to four years, offering a large longitudinal dataset.

Over the course of the LongROAD study, 33 subjects were diagnosed with MCI and 31 with dementia. A series of machine learning models were trained on the LongROAD data, tasked with detecting MCI and dementia from driving behaviors. "Based on variables derived from the naturalistic driving data and basic demographic characteristics, such as age, sex, race/ethnicity and education level, we could predict mild cognitive impairment and dementia with 88 percent accuracy," says Sharon Di, lead author on the new study. Although age was the number one factor for detecting MCI or dementia, a number of driving variables closely followed. These include, "the percentage of trips traveled within 15 miles (24 km) of home ... the length of trips starting and ending at home, minutes per trip, and number of hard braking events with deceleration rates 0.35 g." Using driving variables alone, the models could still predict those MCI or dementia drivers with 66 percent accuracy. The new study was published in the journal Geriatrics.

"Despite early claims by #Tesla #ElonMusk, Autopilot WAS engaged in tragic crash in The Woodlands," tweeted U.S. Congressman Kevin Brady on Wednesday. (Adding "We need answers.")

But maybe it depends on how you define Autopilot. CNN reports: Tesla said Monday that one of Autopilot's features was active during the April 17 crash that killed two men in Spring, Texas....

Lars Moravy, Tesla's vice president of vehicle engineering, said on the company's earnings call Monday that Tesla's adaptive cruise control was engaged and accelerated to 30 mph before the car crashed. Autopilot is a suite of driver assistance features, including traffic-aware cruise control and Autosteer, according to Tesla's website... The North American owner's manuals for the Model 3, Model S and Model X, all describe traffic-aware cruise control as an Autopilot feature. Tesla's revelation may be at odds with the initial description of the crash from its CEO Elon Musk, who said two days after the crash that "data logs recovered so far show Autopilot was not enabled."
Alternately, Forbes suggests there may just be some confusion, noting that earnings call included descriptions of tests Tesla performed on one of their own cars after the accident. So when they said adaptive cruise control "only accelerated the car to 30mph [over] the distance before the car crashed," they could just have been referring to their own experiments. (Tesla also points out adaptive cruise control only engages when the driver is buckled — and disengages slowly if they're unbuckled — and after the Texas crash all seat belts were unbuckled.)

Why so much confusion? Part of the problem may be, as CNN points out, that Tesla "generally does not engage with the professional news media."

But The Drive shares another theory about the crash: A relative of the deceased told a local news station that the owner allegedly "may have hopped in the back seat after backing the car out of the driveway." Moments later, the car crashed when it failed to negotiate a turn at high speed.
CNN adds: Bryan Reimer, the associate director of the New England University Transportation Center at MIT, who studies driver assistance systems like Autopilot, said one of the plausible explanations for the crash is that the driver was confused and thought they had activated Autosteer, when only traffic-aware cruise control had been turned on. "The general understanding of Autopilot is that it's one feature, but in reality it is two things bolted together," said Reimer, referring to traffic-aware cruise control and Autosteer.
But according to the Washington Post, Tesla also disputes that theory: Tesla executives on Monday claimed a driver was behind the wheel at the time of a fatal crash that killed two in suburban Houston this month, contradicting local authorities who have previously said they were certain no one was in that seat. Tesla made the statement on its earnings call Monday... Lars Moravy, the company's vice president of vehicle engineering, said the steering wheel was "deformed," indicating a driver's presence at the time of the crash...

Mark Herman, constable for Harris County Precinct 4, told the station KHOU that police were "100 percent certain that no one was in the driver's seat."

An anonymous reader quotes a report from Ars Technica: Baidu, China's leading search engine, is often compared to Google. And just as Google has spun off Waymo to commercialize self-driving technology, so Baidu is developing self-driving technology of its own. On Thursday, the Chinese search giant announced the launch of what it is calling China's first paid autonomous vehicle service, known as Apollo Go. Arguably, the service is better described as a shuttle service than a taxi service. Customers are picked up and dropped off from one of eight predefined stations. The initial service area is 2.7 square kilometers -- a little over one square mile. The longest route in the network is 5 km (3 miles). That makes the service a lot smaller than the Waymo One taxi service in Phoenix, which has a service area of around 50 square miles.

Still, there's little doubt that Baidu is one of China's leading self-driving companies -- and that China is the world's No. 2 market for self-driving technology after the United States. In total, Baidu is testing fully driverless vehicles in three Chinese cities and is testing its technology with safety drivers in more than two dozen cities. Baidu has even gotten permission to test fully driverless vehicles near its Silicon Valley offices in Sunnyvale. Another Chinese company, AutoX, has been testing fully driverless vehicles in Shenzhen since December. The service has been open to select members of the public since January, though AutoX hasn't started charging for rides. Several other Chinese companies are working on self-driving technology.

Rei_is_a_dumbass shares a report from CNBC: Tesla is defending itself in the U.S. and Germany against allegations that it has violated environmental rules and regulations, according to a new financial filing. In the U.S., the Environmental Protection Agency accused Tesla last week of failing to prove it is in compliance with federal emissions standards for hazardous air pollutants. Specifically, the EPA is seeking details about how Tesla handles "surface coating" of its vehicles. As CNBC has previously reported, the "paint shop" at Tesla's main U.S. car plant in Fremont, California, has a history of problems, including fires, improper cleaning and maintenance. Some vehicle re-touching, to fix flaws in paint on the cars, has been done in a tented "paint hospital" at the Fremont factory, employees previously told CNBC. In 2020, Tesla embarked on massive improvements to its paint facilities, Fremont building permits revealed.

Tesla said in the filing Wednesday that the company "has responded to all information requests from the EPA and refutes the allegations." The company does not expect any "material adverse impact" on its business from its dealings with the EPA in this matter. Tesla is also still tangling with local air quality authorities in California -- the Bay Area Air Quality Management District -- over previously disclosed "notices of violation," relating to "air permitting and related compliance for the Fremont Factory."

In Germany, Wednesday's financial filing said, authorities have fined Tesla 12 million euros, or about $14.5 million, for allegedly failing to make public notifications and properly fulfill their obligations to take back old batteries from customers. German law requires automakers selling electric cars to take back batteries and dispose of them in an environmentally sustainable manner. Tesla wrote in the filing: "This is primarily relating to administrative requirements, but Tesla has continued to take back battery packs." Tesla filed an objection in Germany and said that the matter should not have a material impact on Tesla's business.

"Self-driving" vehicles could be allowed on UK roads by the end of this year, the government has said. The BBC reports: The Department for Transport said automated lane-keeping systems (ALKS) would be the first type of hands-free driving legalized. The technology controls the position and speed of a car in a single lane and it will be limited to 37mph (60km/h). Following a consultation last year, the government has now said that vehicles with ALKS technology can be legally defined as self-driving, "as long as they receive GB type approval and that there is no evidence to challenge the vehicle's ability to self-drive." The government confirmed that drivers will not be required to monitor the road or keep their hands on the wheel when the vehicle is driving itself. But the driver will need to stay alert and be able take over when requested by the system within 10 seconds. If a driver fails to respond, the vehicle will automatically put on its hazard lights to warn nearby vehicles, slow down and eventually stop. The Highway Code is now consulting on what rules will be put into new laws to make sure the technology is safely used. "ALKS as currently proposed by the government are not automated," cautions Matthew Avery, director of research at Thatcham Research. "They are assisted driving systems as they rely on the driver to take back control. Aside from the lack of technical capabilities, by calling ALKS automated our concern also is that the UK government is contributing to the confusion and frequent misuse of assisted driving systems that have unfortunately already led to many tragic deaths. Consumers will expect the car to do the job of a driver, which current models can't do."

An anonymous reader quotes a report from CNET: The most recent crash involving a Tesla Model S and alleged connections to running driver-assist features without a driver behind the wheel spurred a lot of talk on how to handle advanced technology and its growing impact on drivers. Following Sens. Richard Blumenthal and Ed Markey's calls for enhanced guidelines from the National Highway Traffic Safety Administration, the two introduced new legislation on Monday that aims to tackle the problem.

With Sen. Amy Klobuchar signed on as a sponsor, the Stay Aware for Everyone Act would compel the Department of Transportation to study driver-monitoring systems installed in vehicles. With findings delivered to the appropriate committees within 180 days, the Transportation Secretary would then need to finalize a rule within four years deciding if the systems should become mandatory on all new vehicles. Not just vehicles with any level of driver-assist system, like Tesla's Autopilot, but all new cars sold. Automakers would then have two model years to meet compliance with any new vehicles going on sale.

The language in this bill, however, is interesting since it covers all new vehicles, rather than vehicles equipped with advanced assist systems. Naturally, this opens up privacy concerns, and all the bill says on this front is that the Transportation Secretary would determine "appropriate privacy and data security safeguards." The SAFE Act is one of four new bills the pair of Democratic senators introduced today, proposing potential legislation to speed up recall reporting from automakers, to bolster vehicle seat backs to reduce related fatalities and to set up a system to help automakers report possible vehicle defects earlier for NHTSA to investigate.

Lyft will sell its self-driving car unit to Woven Planet, a subsidiary of Toyota, for $550 million in cash, the companies announced Monday. CNBC reports: As part of the deal, Lyft and Woven Planet will work together on enhancing automated driving technology safety, according to a release. "Not only will this transaction allow Lyft to focus on advancing our leading Autonomous platform and transportation network, this partnership will help pull in our profitability timeline," Lyft Co-Founder and President John Zimmer said in a statement.

The company expects the deal will remove $100 million of annualized non-GAAP operating expenses on a net basis, according to the release. Because of that, Zimmer added that if the deal closes when expected in the third quarter and recovery from the pandemic continues, Lyft expects to become profitable on an adjusted EBITDA basis in Q3.

Long-time Slashdot reader DesertNomad summarizes a report from EE Times: It's been known for a long time that the various Global Navigation Satellite System (GNSS) systems are easily jammed; the more "interesting" problem is the potential to spoof a GNSS signal and by spoofing use that to cause GNSS receivers to determine incorrect positions. The challenge lies in the observation that the navigation messages can be constructed by bad actors on the ground. Work going on for several years now has been to provide crypto signatures that have the potential to authenticate valid transmissions. Current commercial receivers can't take advantage of that, so there may be industry-wide needs to update the receiver devices.
"The vulnerability of the global positioning system, or GPS, is widely acknowledged..." reports EE Times: Spoofing creates all kinds of havoc. For example, it can be used to hijack autonomous vehicles and send them on alternate routes. Spoofing can alter the routes recorded by vehicle monitors, or break geofences used to guard operational areas. It also poses a risk to critical infrastructure, including power, telecommunication and transportation systems. Jan van Hees, business development and marketing director for GNSS receiver maker Septentrio, provided these analogies: "Jamming involves making so much noise that the [satellite signal] disappears. Spoofing is like a phishing attack on the signal."

The U.S. Coast Guard has recently tracked a growing number of high-profile incidents involving GPS interference. For example, the loss of GPS reception in Israeli ports in 2019 left GPS-guided autonomous cranes inoperable, collateral damage from the Syrian civil war. In 2016, more than 20 ships off the Crimean peninsula were thought to be the victim of a GPS spoofing attack which shifted the ships' positions on electronic chart displays to land.
The article recommends real-world auditing, testing, and risk assessment, adding that one pending fix is signal encryption "including a framework called open service navigation message authentication (OSNMA)." The OSNMA anti-spoofing service developed for the European GNSS system, enables secure transmissions from Galileo satellites to encryption-enabled GNSS receivers. In the midst of final testing, OSNMA will soon be available free to users... A secret key on the satellite is used to generate a digital signature. Both the signature and key are appended to navigation data and transmitted to the receiver. OSNMA is designed to be backward-compatible, so that positioning without OSNMA still works.

Honda will end production of combustion motors by 2040 as it embarks on a wide-reaching drive to achieve total carbon neutrality by 2050 and to advance the development of its zero-emission powertrain solutions. AutoCar reports: Company president Toshihiro Mibe detailed a series of ambitious objectives at a press conference in Japan today, where he solidified the brand's commitment to leading "advancements which will be made in the areas of mobility, the power unit, energy and robotics." By 2050, Honda aims to achieve carbon neutrality across "all products and corporate activities," which will see it shift focus predominantly to developing environmentally friendly powertrains and overhauling its supply chain to ensure products are "made from 100% sustainable materials."

The brand had already confirmed it would offer exclusively electrified passenger cars in Europe by the end of 2022, but is now solidifying its global electrification strategy for the coming years. By 2030, Honda plans for 40% of its sales to be pure-electric or fuel cell (FCEV) vehicles, rising to 80% by 2035 and 100% by 2040. Specific goals for the European market have yet to be fully detailed, but a strategic partnership with General Motors will accelerate electrification efforts in North America, while a total of 10 new Honda-badged EVs will be launched in the Chinese market "within five years" - the first of which will be the production version of the e:prototype shown at Shanghai last week. Honda has also confirmed that in the second half of the decade, it will launch a range of EVs atop its new 'e:Architecture' platform. The models will arrive in the US first, before being rolled out to other regions, likely including Europe.

Jaguar Land Rover (JLR) is shutting its two main car factories temporarily due to a shortage of computer chips. From a report: The difficulties at Britain's biggest carmaker echo similar problems at other manufacturers, including Ford, who have been hit by a global shortage of chips. JLR said there would be a "limited period" of closure at its Halewood and Castle Bromwich sites from Monday. A mixture of strong demand and Covid shutdowns at chipmakers has also hit phone, TV and video games companies. Tata-owned JLR said in a statement: "We have adjusted production schedules for certain vehicles which means that our Castle Bromwich and Halewood manufacturing plants will be operating a limited period of non-production from Monday 26th April. We are working closely with affected suppliers to resolve the issues and minimise the impact on customer orders wherever possible." Production at a third factory, at Solihull, will continue. The Castle Bromwich factory makes the Jaguar XE, XF and F-Type models, and employs about 1,900 people. Halewood makes the Range Rover, Evoque and the Land Rover Discovery Sport, and has about 4,000 workers.

Alphabet's Wing Aviation is asking U.S. regulators to allow it to expand drone operations as a way to make more efficient deliveries controlled from a central command post. From a report: Wing wants to control its drone flights at a "central hub" from which the remote pilots can oversee operations without being in the aircraft's operating area, the Federal Aviation Administration said Friday in a filing in the Federal Register. The company also wants to launch drones from multiple locations within an operating area, and get FAA permission to receive less frequent checks from the regulator, the filing said. The agency posted the requests without saying whether it will approve them.

Rei_is_a_dumbass shares a report from Ars Technica: Last Saturday, two men died when a Tesla Model S crashed into a tree in a residential neighborhood. Authorities said they found no one in the driver's seat -- one man was in the front passenger seat, while the other was in the back. That led to speculation that the car might have been under the control of Tesla's Autopilot driver-assistance system at the time of the crash. Elon Musk has tweeted that "data logs recovered so far show Autopilot was not enabled." Tesla defenders also insisted that Autopilot couldn't have been active because the technology doesn't operate unless someone is in the driver's seat. Consumer Reports decided to test this latter claim by seeing if it could get Autopilot to activate without anyone in the driver's seat. It turned out not to be very difficult.

Sitting in the driver's seat, Consumer Reports' Jake Fisher enabled Autopilot and then used the speed dial on the steering wheel to bring the car to a stop. He then placed a weighted chain on the steering wheel (to simulate pressure from a driver's hands) and hopped into the passenger seat. From there, he could reach over and increase the speed using the speed dial. Autopilot won't function unless the driver's seatbelt is buckled, but it was also easy to defeat this check by threading the seatbelt behind the driver. "In our evaluation, the system not only failed to make sure the driver was paying attention, but it also couldn't tell if there was a driver there at all," Fisher wrote in a post on the Consumer Reports website.

Audi has revealed its all-electric A6 E-tron concept, a luxury sedan that will come packed with tech including the ability to project video games on to a wall. Tom's Guide reports: The A6 E-tron, which was unveiled at Auto Shanghai 2021 today, is built on the new Premium Platform Electric (PPE) chassis architecture that Audi is developing in collaboration with Porsche. And though a production version of the car isn't likely to be available until later in 2022, its development is well under way; the car you see here shouldn't be miles away from the final version.

The A6 E-tron Concept boasts almost 435 miles of range and comes armed with a 100 kWh battery, which can be replenished from 5 to 80% in under 25 minutes as well as being able to accept fast 270kW charging. Featuring a motor on each axle, with a combined power output of 469 bhp and 590lb ft of torque, the Audi A6 E-tron should be quick, too, with a 0-62 mph time of under 4 seconds. However, Audi also plans PPE-based models with a single motor mounted on the rear axle to keep energy efficiency and prices in check.

Standout cosmetic touches include digital matrix LED headlights, which have the party trick of being able to project images. Audi suggests that owners can park facing a wall during recharging and pass the time playing a video game using the technology, or watch a movie. Audi has even developed a game, which is playable via a smartphone, to show how the concept works. Four more LED projectors are housed in the corners of the car to shine animated turn signals on the road. OLED technology in the taillights promises more electrical trickery and there are additional projectors that switch on when the doors are opened. These, suggest Audi, can be used to issue greetings to passengers or warnings to passing cyclists when the doors are opening.

Rei writes: After a Tesla crash in The Woodlands killed two people last Saturday night, news reports were quick to jump to the conclusion that Autopilot (or even FSD) was being used and led to the strange crash, in which investigators reported nobody in the driver's seat, one victim buckled in in the front passenger seat, and the other buckled in behind them. On Twitter, however, Autopilot users were quick to question this account, noting that Autopilot can't be enabled on a road lacking lane lines; the speed and acceleration were far higher than Autopilot allows; and numerous other problems. Now Elon Musk has weighed in with the first official statement since the crash. Responding to a user questioning the reporting, Musk said: "Your research as a private individual is better than professionals @WSJ! Data logs recovered so far show Autopilot was not enabled & this car did not purchase FSD. Moreover, standard Autopilot would require lane lines to turn on, which this street did not have." What actually caused the crash and why nobody was found in the driver's seat remains unclear at this point; analysis of the logs and investigation of the crash site remains ongoing.
