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