It’s not your imagination: Cars have gotten taller over the past few decades. Safety regulations influence automotive designs in ways that laypeople may not realize. In particular, hoods have gotten higher; manufacturers are required to raise them above the engine block, leaving a gap, so that if the car strikes a pedestrian and their head strikes the hood, the hood has room to deform and thus cushion the blow.<\/p>\n

Perhaps forthcoming regulations will alter automotive design parameters further. The Insurance Institute for Highway Safety (IIHS) recently noticed a spike in pedestrian and bicycle fatalities, prompting a study<\/a>. What they found is that “The forward blind zones of six top-selling passenger vehicles grew substantially over the past 25 years.” Taller hoods, thicker A-pillars and larger sideview mirrors are shrinking our forward field of view.<\/p>\n<\/p>\n

By placing camera rigs in a variety of car models, then running the visuals through computational sotware, the study created 360-degree blind zone maps. In the animation below, the blue area\u2014which is disturbingly large, as the red pedestrian is about to learn\u2014indicates the blind spots of a sample vehicle:<\/p>\n<\/p>\n

The study found an across-the-board increase in forward blind spots over a 25-year period of vehicle design with, unsurprisingly, SUVs doing the worst.<\/p>\n

“Goal: Researchers measured the blind zones of six top-selling light-duty vehicle models (one pickup truck, three SUVs, and two passenger cars) across multiple redesign cycles (1997-2023) to determine whether the blind zones were getting larger.
\n“Results: In the 10-m forward radius nearest the vehicle, outward visibility declined in all six vehicle models measured across time. The SUV models showed up to a 58% reduction in visibility within a 10-m radius. Other vehicles exhibited smaller (7%-19%) reductions.”<\/p>\n

The news isn’t all bad\u2014though the results are still mixed: “At longer distances (10 m to 20 m), vehicles demonstrated both increases and decreases in visibility.”<\/p>\n

Auto designers don’t need to crumple up all of their new sketches just yet; the IIHS says further study is required. <\/p>\n","protected":false},"excerpt":{"rendered":"
