The only time i use my cell while driving is when it rings then i don't say hello i say i'll call you back in 5 and hang up, no byes. yeah i'm an ass. and yes it is a major safety concern. I've almostbeen hit way too many times because of this. I don't care who you are, you don't NEED to talk on the phone while driving. Pull over if it's important damnit.
