Cars' Forward Blind Zones Are Worse Now Than 25 Years Ago

2 weeks ago
Longtime Slashdot reader sinij shares a report from Car and Driver with the comment: "Lack of visibility is a significant consequence of improving safety on the front overlap crash testing." Here's an excerpt from the report: The Insurance Institute for Highway Safety has a new method to look at what drivers can't look at, and the results of a DOT study using the method suggest that things have gotten worse over the past quarter-century. [...] For the study, researchers with the U.S. Department of Transportation's Volpe Center used the IIHS method to examine every generation of some popular vehicles sold between 1997 and 2023. The models chosen were the Chevrolet Suburban, the Ford F-150, the Honda Accord, the Honda CR-V, the Jeep Grand Cherokee, and the Toyota Camry. The analysis measured how much of a 10-meter radius is visible to a driver; this distance was chosen because that's approximately how much space a driver needs to react and stop when traveling at 10 mph. The study also measured visibility between 10 and 20 meters from the vehicle. The biggest model-specific difference was observed with the Honda CR-V. In a 1997 model, the researchers measured 68 percent visibility, while the 2022 came in at just 28 percent. In a 2000 Suburban, the study measured 56 percent visible area within the 10-meter radius, but in a 2023 model it was down to 28 percent. The study concluded that higher hoods on newer versions of both models had the biggest impact on outward visibility. The F-150 started out with low visibility (43% for a 1997 model) and also declined (36% for the 2015 version). The two sedans in the study saw the least regression: A 2003 Accord was measured at 65 percent visibility, with the 2023 close behind at 60 percent, and the Camry went from 61 percent for the 2007 model to 57 percent for a 2023. Results for visibility between 10 and 20 meters were mixed, with some improving and others decreasing over subsequent generations. While this is not conclusive evidence across the industry, the results from these representative vehicles suggest an overall decline in outward frontal visibility. The study also notes that, during the same time period, pedestrian and bicyclist deaths on U.S. roads increased dramatically -- 37 and 42 percent, respectively. There's likely at least some causation with that correlation, even when you consider the addition of features such as automated emergency braking that are meant to intervene and prevent such collisions.

Fed Chair Powell Says AI Is Coming For Your Job

2 weeks ago
Federal Reserve Chair Jerome Powell told the U.S. Senate that while AI hasn't yet dramatically impacted the economy or labor market, its transformative effects are inevitable -- though the timeline remains uncertain. The Register reports: Speaking to the US Senate Banking Committee on Wednesday to give his semiannual monetary policy report, Powell told elected officials that AI's effect on the economy to date is "probably not great" yet, but it has "enormous capabilities to make really significant changes in the economy and labor force." Powell declined to predict how quickly that change could happen, only noting that the final few leaps to get from a shiny new technology to practical implementation can be a slow one. "What's happened before with technology is that it seems to take a long time to be implemented," Powell said. "That last phase has tended to take longer than people expect." AI is likely to follow that trend, Powell asserted, but he has no idea what sort of timeline that puts on the eventual economy-transforming maturation point of artificial intelligence. "There's a tremendous uncertainty about the timing of [economic changes], what the ultimate consequences will be and what the medium term consequences will be," Powell said. [...] That continuation will be watched by the Fed, Powell told Senators, but that doesn't mean he'll have the power to do anything about it. "The Fed doesn't have the tools to address the social issues and the labor market issues that will arise from this," Powell said. "We just have interest rates."

A Developer Built a Real-World Ad Blocker For Snap Spectacles

2 weeks ago
An anonymous reader quotes a report from UploadVR: Software developer Stijn Spanhove used the newest SDK features of Snap OS to build a prototype of [a real-world ad blocker for Snap Spectacles]. If you're unfamiliar, Snap Spectacles are a bulky AR glasses development kit available to rent for $99/month. They run Snap OS, the company's made-for-AR operating system, and developers build apps called Lenses for them using Lens Studio or WebXR. Spanhove built the real-world ad blocker using the new Depth Module API of Snap OS, integrated with the vision capability of Google's Gemini AI via the cloud. The Depth Module API caches depth frames, meaning that coordinate results from cloud vision models can be mapped to positions in 3D space. This enables detecting and labeling real-world objects, for example. Or, in the case of Spanhove's project, projecting a red rectangle onto real-world ads. However, while the software approach used for Spanhove's real-world ad blocker is sound, two fundamental hardware limitations mean it wouldn't be a practical way to avoid seeing ads in your reality. Firstly, the imagery rendered by see-through transparent AR systems like Spectacles isn't fully opaque. Thus, as you can see in the demo clip, the ads are still visible through the blocking rectangle. The other problem is that see-through transparent AR systems have a very limited field of view. In the case of Spectacles, just 46 degrees diagonal. So ads are only "blocked" whenever you're looking directly at them, and you'll still see them when you're not.
