Texting while driving -

I don't understand how anyone thinks they can text while driving.  How can one look down while hurtling along in a car, and not think something bad could happen. This is a tragic accident that seems avoidable.  I'm sure it will lead to another law, but I don't understand why it isn't common sense.
