Chevy Silverado EV Drives 1,059.2 Miles on a Single Charge, Surpassing World Record

2 weeks 4 days ago
"General Motors claimed a new world record for EV driving on a single charge," reports the Verge, "after a Chevy Silverado EV traveled 1,059.2 miles without recharging its battery." The potentially record-breaking run took place over seven days on public roads near GM's Milford Proving Ground and Detroit's Belle Isle "using smart driving techniques" that included limiting the speed to 20-25 mph. The truck was a 2026 Chevy Silverado EV Work Truck with an EPA-estimated range of 493 miles. But by making a number of adjustments, GM's engineers were able to far surpass the vehicle's estimated range... First of all, the test was conducted in the summer for "optimum ambient temperature for battery efficiency," GM says. They also lowered the windshield wiper blades to reduce drag, inflated the tires to the highest acceptable pressure for lower rolling resistance, removed the spare tire to lighten the load, and optimized the wheel alignment. A tonneau cover was added to the truck bed for smoother airflow, and climate control was turned off for the duration of the test. GM isn't seeking the Guinness World Records, the article adds, with a GM spokesperson calling it "a passion project led and executed by GM engineers." (The test "started out as casual conversation among a group of GM engineers in late 2024," GM says, but "quickly turned into a challenge: How far could the Work Truck go if we optimized absolutely everything?") After the test, reports Motor Trend, "The dead truck was hauled back to Milford, its battery was topped up, and the energy used to power a Stratasys F370 3D printer, which spent 6.5 hours printing an ABS plastic trophy to commemorate the auspicious event."

Students Have Been Called to the Office - Or Arrested - for False Alarms from AI-Powered Surveillance Systems

2 weeks 4 days ago
In 2023 a 13-year-old girl "made an offensive joke while chatting online with her classmates," reports the Associated Press. But when the school's surveillance software spotted that joke, "Before the morning was even over, the Tennessee eighth grader was under arrest. She was interrogated, strip-searched and spent the night in a jail cell, her mother says." Her parents filed a lawsuit against the school system, according to the article (which points out the girl wasn't allowed to talk to her parents until the next day). "A court ordered eight weeks of house arrest, a psychological evaluation and 20 days at an alternative school for the girl." Gaggle's CEO, Jeff Patterson, said in an interview that the school system did not use Gaggle the way it is intended. The purpose is to find early warning signs and intervene before problems escalate to law enforcement, he said. "I wish that was treated as a teachable moment, not a law enforcement moment," said Patterson. But that's just one example, the article points out. "Surveillance systems in American schools increasingly monitor everything students write on school accounts and devices." Thousands of school districts across the country use software like Gaggle and Lightspeed Alert to track kids' online activities, looking for signs they might hurt themselves or others. With the help of artificial intelligence, technology can dip into online conversations and immediately notify both school officials and law enforcement... In a country weary of school shootings, several states have taken a harder line on threats to schools. Among them is Tennessee, which passed a 2023 zero-tolerance law requiring any threat of mass violence against a school to be reported immediately to law enforcement.... Students who think they are chatting privately among friends often do not realize they are under constant surveillance, said Shahar Pasch, an education lawyer in Florida. One teenage girl she represented made a joke about school shootings on a private Snapchat story. Snapchat's automated detection software picked up the comment, the company alerted the FBI, and the girl was arrested on school grounds within hours... The technology can also involve law enforcement in responses to mental health crises. In Florida's Polk County Schools, a district of more than 100,000 students, the school safety program received nearly 500 Gaggle alerts over four years, officers said in public Board of Education meetings. This led to 72 involuntary hospitalization cases under the Baker Act, a state law that allows authorities to require mental health evaluations for people against their will if they pose a risk to themselves or others... Information that could allow schools to assess the software's effectiveness, such as the rate of false alerts, is closely held by technology companies and unavailable publicly unless schools track the data themselves. Students in one photography class were called to the principal's office over concerns Gaggle had detected nudity. The photos had been automatically deleted from the students' Google Drives, but students who had backups of the flagged images on their own devices showed it was a false alarm. District officials said they later adjusted the software's settings to reduce false alerts. Natasha Torkzaban, who graduated in 2024, said she was flagged for editing a friend's college essay because it had the words "mental health...." School officials have said they take concerns about Gaggle seriously, but also say the technology has detected dozens of imminent threats of suicide or violence. "Sometimes you have to look at the trade for the greater good," said Board of Education member Anne Costello in a July 2024 board meeting.
