Do you sing in the car? If you do, your reaction times are slower than if you drive along in silence, according to Australian researchers.
They also found that singing drivers drive at more varied rates, though overall more slowly. They also showed less movement within lanes than those driving without musical accompaniment either from themselves or the radio.
The researchers are Genevieve M Hughesa, Christina M Rudin-Brown, and Kristie L Young from the Department of Psychology, Monash University.
