Talking hands-free on a mobile phone while driving is just as distracting as talking on a hand-held phone, despite one being illegal and the other not, a Queensland University (Australia) road safety study has found. – Which is ridiculous. Cell phones should not operate at all in cars.
“The reaction time of drivers participating in either a hand-held or hands-free conversation was more than 40 per cent longer than those not using a phone….
“This shows hands-free and hand-held phone conversations while driving have similar detrimental effects in responding to a very common peripheral event of a pedestrian entering a crossing from the footpath.”
Conclusion: Don’t use a phone at all while driving!
