studies have shown time and time again that just the act of being distracted from the road is bad. if you are talking to someone on the phone, or even in the car with you... or if you are even listening to the radio, these are all equally distracting. it is entirely possible to text while driving safely so long as you are not moving while you are texting or if you are using a hands free device.
the real issue at hand is that dumbasses have decided that they can take their eyes off the road while they are moving to type a text. people also take their eyes off the road to talk with people next to them... or behind them. is it really a good idea to ban everyone from texting while in the car because a few people are dumbasses? i text only when i'm stopped at a light, technically that is illegal, despite the fact that there is absolutely no way it can affect my driving..
