For those who say its wrong, would talking to a passenger in the car be wrong? Is has been shown that even hands free talking on a cell phone causes nearly as much distraction. (I read a study on this in psychology) It is merely the act of carrying on a conversation that slows reaction time. Just because you are holding a phone doesn’t make it much different than talking to a person next to you.
