I think cell phone usage is addictive and it has simply gotten out of control. I have heard women in public bathrooms talking on their cell phones. I don't even want to think about this practice too much.
I say if a call can't wait, it is not worth having, unless it is an emergency. I am somewhat addicted to my phone and I hate it. I feel like I have to have it with me 24/7. I agree, how did we manage in the old days? We did somehow. Technology is great and all of that, but it does get in the way of our rational thinking. If it's dangerous, don't do it! We don't need anyone to tell us when we are behaving in a manner that could pose a danger to ourselves and others. We truly need to disconnect sometimes. 99% of the time I will not answer my phone when I'm driving. And, I absolutely will not text. I'm not even that good of a typist to be texting while driving
Finally, we don't need laws to tell us how to be safe. I know I don't. But, for those of us who do need rules on the proper use of texting, talking, and driving, you should listen. For the most part laws are there to protect us from ourselves.
