Texting is totally wrong as you take your eyes off the road and I will say using phone is wrong not because I cant do it properly but i have seen 99% in Pak who when are on phone they just forget driving they will slow down or will have no idea where they are goin :p.
For My Self i will say what once Clarkson said, talking on phone is like talking to other occupants in the car, that have no effect on my driving, same goes for mobile phone.
