pondering distracted driving

How much distraction is too much? I don't text and drive - it's all I can do to type out a text message on those tiny little keys while I'm sitting still on my sofa.  I don't talk on my cell phone while I'm driving or do my make up or drink hot coffee or any of a long list of things that might be considered distracting.  I do, however, like to listen to recorded books on CDs, and, while I don't change the CDs while I'm driving (my nifty CD player can be loaded with 6 CDs at a time) I must admit to getting pretty involved in the exciting parts of a story.  I've caught myself driving faster during chase scenes. I'm not ready to give up on my stories full time but I'm compromising.  Whenever I'm involved in white knuckle driving, you know, in ice or snow or pouring rain, I turn off the radio.  That's as much as I can promise right now.
