Two facts.
First, several european countries have banned cell phones in cars if handled without free-speaking device (room micro). The statistical link between free handed cell phones whiule driving and traffic accidents was found to be highly significant/valid in several independent studies which were partially run over years.
Second, in the early nineties I remember a study that was done in Germany, concerning driving and music. Music directly influence brain activities, on a neurological level, and thus it regulates temper, emotional state, mental concentration, memories, mood. Music literally rushes to your brain indeed. Everyone of us knows that from his own experience. The most distracting music style, poison for secure driving, is German "Volksmusik" (terrible music indeed), followed by, I hope I remember correctly, American country. Hard Rock and heavy stuff also was found to be bad, because the heavy rythm and often agressiveness causes massive distraction. Best music to listen while driving is from the Jazz and Swing department, it helps to envoke a state of relaxed concentration.
Just two scientific findings. so if you want to be on the safe side, always have a solid reserve of Glenn Miller songs aboard!
