Children cannot judge acceleration of vehicles travelling quicker than 20 mph accurately.

The results suggest that while adult pedestrians could make accurate judgments for automobiles travelling up to 50mph, children of principal school age group become unreliable after the approach speed goes above 20mph, if the automobile is five seconds aside. Professor John Wann, from the Division of Psychology at Royal Holloway, who led the research, says: This is not a matter of kids not paying attention, but a nagging issue linked to low-level visual recognition mechanisms, so even when children are paying very close attention they may fail to detect a fast approaching vehicle.
