RACQ's study was prompted by local and international media reports suggesting near silent hybrid vehicles presented a greater hazard to pedestrians than other cars.
Steve Spalding said the study tested the ability of pedestrians to detect hybrid and petrol vehicles in real-world conditions, using hearing alone. "The results showed that while hybrid vehicles could be nearly silent, modern conventional engines are quiet enough that pedestrians have just as much difficulty detecting them in situations where there is traffic noise. All pedestrians need to be aware of the potential risks modern vehicles of all types pose and take appropriate action to ensure their safety.""
