The primary factor that correlates with reverse cameras reducing backup accidents is age - people over 70 have higher backup accidents rates without cameras/sensors. FTA: > When averaged between the 2 automakers, effects were significantly larger for drivers 70 and older (38% reduction) than for drivers younger than 70 (1% increase); effects were significant for older but not younger drivers. A big SUV is probably an exacerbating factor, though. Also, for any kind of car, rear cameras and sensors decrease impacts while parallel parking. I see far fewer damaged bumpers on newer cars these days.
