not to mention looking at the phone to dial it or read a text or simply push the button to answer the thing, bam your in the back end of a stopped vehicle. I hit someone who opened a car door while I was adjusting the channel on my radio once. Shit happens but we really don't need more reasons for shit to happen. I actually saw a women sitting at a red light and she had both hands on the wheel but a cig in one and a cell phone in the other.
