A recently-released study by the National Highway Traffic Safety Administration (NHTSA) finds that hybrid vehicles are more likely than conventional cars to hit pedestrians, especially while turning.
The study, conducted on 8,387 hybrids and 559,703 conventional vehicles with internal combustion engines, showed that the “incidence rate of pedestrian crashes in scenarios when vehicles make turns was significantly higher” for hybrids. It also concluded that hybrids were “two times more likely to be involved in a pedestrian crash” while slowing, stopping, backing up, and entering or leaving a parking space.
Advocates for the blind have long argued that hybrids are more dangerous than conventional vehicles because they are quieter. Earlier this year, the Japanese government set up a panel to study the idea of adding sounds to hybrid vehicles. Proposed sounds included artificial engine noises, music, or even ring tones, like those in cell phones. An informal study conducted by the Japanese Federation of the Blind also showed that more than half of blind pedestrians were “terrified” of hybrids.
In its accident analysis, NHTSA concluded that “a statistically significant effect was found due to engine type.”
