Things are getting nutty in the world of vehicle fuel economy standards.
Last week, Transportation Secretary (and ex-reality TV contestant) Sean Duffy declared that he was resetting the Corporate Average Fuel Economy (CAFE) standards that govern vehicle fuel efficiency in the US. Duffy confidently declared that the current CAFE standards, in which fuel economy would increase 2 percent per year for passenger car model years 2027–2031 and 2 percent per year for light-duty trucks model years 2029–2031, “illegally” considered electric vehicles, and therefore were null and void. So while it works on reversing those standards, Duffy said the Trump administration would simply stop enforcing the current ones.
The rules were being rewritten to make “vehicles more affordable and easier to manufacture in the United States,” Duffy said. Experts say rolling back the CAFE standards will have the opposite effect: cars will be less fuel efficient, forcing their owners to shell out more for gas over time.

“Making our vehicles less fuel efficient hurts families by forcing them to pay more at the pump,” Katherine García, director of the Sierra Club’s Clean Transportation for All program, said in a statement. “This action puts the well-being of our communities at risk in every way imaginable. It will lead to fewer clean vehicle options for consumers, squeeze our wallets, endanger our health, and increase climate pollution.”
The CAFE standards were first issued in response to the 1973 energy crisis. The law requires the National Highway Traffic Safety Administration to set standards for the “maximum feasible” average fuel economy levels that car and truck manufacturers can achieve in their fleets in a given model year.
If the Biden rules were allowed to play out, new cars and passenger trucks would have to travel on average 50.4 miles per gallon by 2031. Individual vehicle owners would save an average of $600 in fuel costs over the life of their vehicles. And the US would avoid having to burn more than 70 billion gallons of gasoline through 2050, resulting in more than 710 million metric tons of pollution out of the air — the equivalent of taking more than 230 million vehicles off the road.
Meanwhile, Senate Republicans are racing ahead with a budget reconciliation bill that would zero out fines for automakers that fail to meet the current CAFE standards — in effect making those rules completely toothless. Noncompliance fines have brought in hundreds of millions of dollars to the federal coffers over the years. Stellantis, which owns Jeep and Dodge, paid over $400 million in civil penalties from 2016–2019, and then $190.7 million from 2019–2020, while General Motors paid $128.2 million in 2016–2017, Reuters reports.
“This action puts the well-being of our communities at risk in every way imaginable.”
Naturally, the automakers are giddy at the possibility of zero consequences for exceeding fuel economy standards. “The standards are out of sync with the current market reality and immediate relief is necessary to preserve affordability and freedom of choice,” Stellantis told Reuters. The Alliance for Automotive Innovation, which represents Detroit’s Big Three automakers, praised the Republican bill, as well as Duffy’s novel interpretation of the current CAFE standards. In 2022, this same group praised President Joe Biden’s CAFE standards as “good and appreciated.”
These are the same companies that used to claim to care about fighting climate change and creating a world with “zero emissions,” as GM once said. Carlos Tavares, who recently resigned as CEO of Stellantis, said last October that he supports stricter emission and fuel economy rules in Europe and the US because he wanted to be on “the right side of history.” He recalled in wrenching detail the experience of his daughter driving through a wildfire in Portugal, in which the heat was so intense it melted the door panel of her car.
Now, when faces with proposals that would worsen the effects of climate change by allowing automakers to make more polluting vehicles, those same automakers are enthusiastic in their support.
This shouldn’t come as any surprise. Automakers were complicit in the first Trump administration’s attempt at weaken fuel economy standards. And they support the administration’s efforts to nullify California’s ban on the sale of gas-powered cars and trucks by 2035. They are firmly on the side of making more money, not preventing wildfires and floods caused by a heating planet.

![Midjourney goes from generating cat images to full-body ultrasound scansMidjourney CEO David Holz just showed off the company’s first hardware product and plans to build a San Francisco spa, which he admitted is a bit different from the “cat pictures” produced by its AI image generator. Dubbed The Midjourney Scanner, it’s an ultrasound-based full-body scanner that uses a ring of sensors to capture vertical slices of the inside of your body, looking at the composition of your muscle, fat, bone, and organs to start. Holz said ideally, you could do this once a year or every single day, as it “aims for image quality comparable to MRI in many ways.”He mentioned that one way he’d like to use it would be to see how his body changes in response to diet and workout changes, saying, “I’m not the most measured man on Earth yet, you know, but maybe I want to have that daily [measurable information]. A set of job listings advertises the company’s goal as trying to “build and launch the world’s first full-body ultrasound CT scanner, ultimately bringing safe, fast, and high fidelity preventative scanning to billions via a magical spa experience.”The Midjourney Scanner was developed in a partnership with ultrasound tech company Butterfly Network, which said it uses “40 Butterfly Ultrasound-on-Chip™ imaging modules per system.”The scanning process starts with stepping onto a platform that drops down into the water on rails through a ring of thousands of transducers that create ultrasonic waves and then record the ripples from them passing through your body to analyze them and create detailed 3D images, saying the scan will take about 60 seconds. Holz said about a dozen people have been scanned so far.It starts by stepping into a shallow pool of golden light. You then begin to descend into the water. Your body passes through a ring of underwater sensors, each acting like a dolphin, using its echolocation. The sensors send ultrasonic sound waves through your body from every angle. With enough waves, and enough angles, we form an image of what’s happening inside your body.It combines those sensors with two petaflops of processing power. But after watching the livestreamed reveal, I’m still unclear on what Midjourney’s AI image generation tech exactly has to do with the Midjourney Medical effort, beyond an alternative business for otherwise-unused AI compute.Holz hopes to put 10 of the scanners into a Midjourney Spa location in San Francisco’s Union Square that will open before the end of 2027, and offered to scan the hands of attendees at its launch event. The Midjourney Spa will have a gym, saunas, and cold plunges to go along with the hot tub-equipped scanning rooms where visitors will get into the water to be scanned.He did mention that various medical applications would require FDA clearances, but for now, Midjourney Medical says it’s working on “body composition maps” that don’t require the same level of clearance as diagnostic imaging. It also says the “library of scans” users create can be shared with doctors, AI health tools, or others, and that “We take data privacy seriously — more details on our data policies will come as we get closer to launch.”Holz suggested that eventually these scans could become better than an MRI, without radiation, powerful magnets, or other complicating factors, to get a look at what’s going on inside people’s bodies “real fast.” In response to a question, he imagined a future where the FDA had a class of devices to look at “weird” things and allowed people to “just try to get as much data as we can.”#Midjourney #generating #cat #images #fullbody #ultrasound #scansAI,Health,News,Science](https://i3.wp.com/platform.theverge.com/wp-content/uploads/sites/2/2026/06/ultrasound_phantom_segmentation-b254a71d083eb5c9.png?quality=90&strip=all&crop=28.441715022566%2C0%2C70.316569954868%2C100&ssl=1 "Midjourney goes from generating cat images to full-body ultrasound scansMidjourney CEO David Holz just showed off the company’s first hardware product and plans to build a San Francisco spa, which he admitted is a bit different from the “cat pictures” produced by its AI image generator.
