I NEVER text while driving.
Not because I'm all that safety conscious, it's mainly because even sitting in a quiet room with no distractions it takes me about 15 minutes to poke in a basic text message and send it on my cell phone.
For me, texting while driving is pretty much an impossibility.
I am, however, guilty of photographing while driving.
But at least I don't put the camera to my eye. I just hold it out over the dash and shoot through the windshield.
Not real dangerous, unless the leaning photos make you dizzy or something.
