You should NEVER talk on the phone while your driving. A study was done and it totally eliminates your peripheral vision whether you have bluetooth or not. It is responsible for a HUGE amount of deaths every year. Do yourself a favor and pull over if you need to talk. Maybe think about all the kids that have been killed in the past year and how many lives have been ruined. It's just a totally selfish thing. Sorry, my rant is over. As you can see this topic drives me nuts because I've had a few close calls with people as well that were on a cell phone and weren't paying attention.
