We have had this conversation before. Police not only talk on the phone but also type on the computer and look at the display when they are driving. Often they are in pursuits when doing this. If it's safe enough for them to do an intelligent person like myself who multitasks quite well can keep her attention on the road.
I just worked five years a job where I was driving constantly and talking on the phone. Never even a close call because I was paying extra attention.
And yes I did HAVE to talk on the phone if I would have pulled over each time I would have been fired a long time ago for exceeding my monthly allotment of hours.
Lots of working driving people MUST talk and drive at the same time.
I recently got a Bluetooth and I like it.
