Driving with cell phones

[Ghoulish Delight]

Would I be in trouble for continuing to use my phone as a music player? Would selecting the next podcast to listen to be verboten? Is it somehow more dangerous than someone scrolling through their poorly organized directories via LCD display on the MP3 CD that's in their car stereo simply because theirs is built into the dashboard?

I understand, and possibly even agree with, the impetus behind the recommendation. But enforcement I think will be inconsistent at best.

I was mistakenly pulled over for talking on my cell phone because I was resting my head on my hand and my long hair covered me ear, therefore a cop decided I must be on the phone. If they can't even determine accurately whether someone had a device physically against their head, what chance do they have of accurately determining other far less obvious uses of portable devices?
