  • Gas Cars Fall Below 50% of Global New Car Sales for the First Time
    by EditorDavid on 11/10/2026 at 9:10 pm

    "Gas cars are now a minority of the world's new car sales," reports Electrek. Gasoline-only vehicles made up 49% of global new-vehicle sales in the first half of 2026, down from 73% in 2021, according to Mobility Global data first reported by Nikkei. It's the first time on record that they've been under half. But there's a catch: most of the cars taking their place still have a gas tank... [The share of gas-only vehicles] fell three points in a single year, from 52% to 49%. Battery-electric vehicles grew 12% to 6.87 million units and took 17% of the market, up three points. Conventional hybrids grew 10% to 7.27 million units, or 18%... [T]he rest is diesel, plug-in hybrids and a few minor fuels. Nikkei ties the acceleration to oil. Fuel prices spiked with the conflict in the Middle East, and buyers went looking for lower running costs. The whole car market shrank about 5% in the first half, according to the IEA, so gas-only sales fell twice as fast as the market. Gas car sales dropped the most in China, down 26%, followed by Europe at 13%... Mobility Global has battery-electric sales up 32% in Europe to 1.81 million, up 81% in Southeast Asia to 350,000, and more than doubling in Oceania to 110,000... Yoshiaki Kawano, an associate director at Mobility Global, told Nikkei that few EV buyers go back to gasoline cars or hybrids. He expects demand based on "genuine consumer needs rather than subsidies" to grow as prices come down... [Hybrids] outsold battery-electric vehicles in the first half, 7.27 million to 6.87 million... Only the 17% that's battery-electric burns no fuel at all. So about 83% of the new vehicles sold in the world this year still came with an engine. The article notes that U.S. hybrid sales were up 23%, reaching a record 16.3% of vehicles sold in the second quarter of 2026, while the share of ICE vehicles went down. Gas-only cars went from 73% to 49% of the market in less than five years, and nothing in the data suggests they're getting that share back. The last time gasoline wasn't on top was the early 1900s, when steam and electric cars outsold it in the US. I hate seeing media headlines claiming that "EV sales are down" and that "EV growth has stalled." The data is clear: that's true in the US, but only in the US. The rest of the world is moving to electric vehicles, and it is not slowing down. Read more of this story at Slashdot.

  • 'The Social Reckoning' Bombs with $5.5 Million Opening
    by EditorDavid on 11/10/2026 at 8:10 pm

    Why didn't The Social Reckoning enjoy the box office success of 2010's The Social Network, asks IndieWire/A>: [T]here wasn't the same urgency in the story being told. The Social Reckoning focuses less on Zuckerberg, and more on data engineer Frances Haugen's decision to blow the whistle on how Facebook's algorithms were promoting political content that radicalized users, as well as the company's awareness of how its products were contributing to a rise in bullying and teen suicide... [B]ut The Social Reckoning arrives as a much greater threat has emerged from Silicon Valley. Artificial intelligence is dominating the headlines, as fears mount about the economic disruptions it will unleash when millions of jobs are replaced by machines, and, graver still, its potential to trigger a world-ending event... And it's not like Haugen's testimony led to lasting change at Facebook... As IndieWire's Ryan Lattanzio put it, "'The Social Reckoning' argues that the aftermath of their whistleblowing is still somehow felt today. In actuality, living as we do in 2026, it pretty much feels like... no one cared, and nothing changed?" After the first movie's director bowed out, Sony Pictures shied away from selling it as a sequel — but the problems run deeper, the article adds. "The Social Reckoning isn't just a financial failure, it's a critical one, too. The reviews were blistering..." Although on the bright side, "Sony wisely kept The Social Reckoning's budget at $30 million, meaning it won't face losses on the scale of a Digger... " Variety writes that Digger "cratered in its second weekend with $3.2 million from 3,321 theaters, a 60% decline from its dismal $8 million debut. So far, the Tom Cruise satire has limped to $14 million domestically and $35.3 million globally. Warner Bros. spent above $160 million to produce the film, which is shaping up to be one of the biggest bombs ever..." Read more of this story at Slashdot.

  • A College Told Flock to Remove Its Cameras. The Company Refused.
    by EditorDavid on 11/10/2026 at 4:34 pm

    The Chicago Sun-Times reports: When Elgin Community College hired Flock Safety to install six surveillance cameras in April 2025, President Peggy Heinrich thought they would "enhance the safety and security of students...." They were supposed to help locate stolen cars and missing people. But Heinrich started to wonder if the cameras were actually making students less safe after seeing news reports that data captured by Flock cameras in Illinois had been shared with U.S. Customs and Border Protection. Then in September 2025, Immigration and Customs Enforcement detained an Elgin Community College student in a campus parking lot. More than half of students at the far west suburban Chicago campus identify as Latino. Heinrich said enrollment dipped. Students were afraid to come to class. College officials decided the cameras had to go... College officials asked Flock to remove the surveillance cameras "out of an abundance of caution for our students," Heinrich said. But getting the cameras taken down was not as simple as it sounds, especially because Flock retains ownership of the company's equipment.... Surveillance experts say the company is financially incentivized to have as many cameras gathering data as possible even in places that no longer want them, because potential clients are looking for the surveillance network with the greatest reach.... Elgin Community College staff notified Flock in October 2025 that they wanted to cancel their contract and have the cameras taken down. Within a day, Heinrich said, Flock rejected the request and refused to uninstall the equipment on the basis that the company had not breached their agreement. College officials reached out again in December 2025 and said they would pay for the remaining five months of the contract — they just wanted the cameras taken down. "We never received a response back from Flock," Heinrich said. That's when things got weird. Heinrich said Elgin Community College staff began to cover the cameras using black trash bags and zip ties so that they would not be able to capture footage. But workers in an unmarked vehicle, which Heinrich assumed belonged to Flock, repeatedly removed the coverings... This strange dance continued, Heinrich said, until Elgin Community College's contract with Flock expired in April this year and the company uninstalled the cameras for good.

  • US Agency To Rewrite Rules To Finally Address Vehicle Headlight Glare
    by EditorDavid on 11/10/2026 at 2:34 pm

    America's National Highway Traffic Safety Administration "said on Tuesday that it will rewrite its vehicle lighting standards," reports Reuters, "to address concerns about headlight glare and allow for the latest safety-improving lighting technologies." NHTSA said it plans to improve rules for LEDs, dusk sensors, automatic high beams and replaceable light sources. The agency will also evaluate headlamp height and aim and how they impact driver visibility and address headlight glare and make appropriate changes. Complaints about glare from headlights have increased and some lawmakers have urged the government to set a maximum headlight brightness standard. A growing number of taller trucks and SUVs on roads has also led to more complaints about glare. LEDs, which now account for most headlights in new cars, are much brighter than traditional halogen headlights... The issue still accounts for a small number of nighttime crashes, according to a study last year from the Insurance Institute for Highway Safety (IIHS). The study noted that headlight glare contributes to far fewer crashes than insufficient visibility... Federal headlight standards for minimum and maximum brightness have not changed since 1997, IIHS noted. The study found that drivers older than 70 appear to be most affected by headlight glare. In 2022, NHTSA said it would allow automakers to install adaptive driving beam headlights on new vehicles. The devices adjust the headlight beam pattern to dim portions directed at other vehicles.
