smartphone while driving

Yes, I use my smartphone while driving - to receive phone calls. I used my previous non-smartphone to do the same thing.
I also use it for navigation and here's the rub: most of the time spoken directions are right, but when I travel around the d.c. area there are ALWAYS wrong (for that matter, so is the GPS I occasionally use). Sometimes I need to look at the screen to see directions. My wife tells me to pull over when I do this - I need to listen to her wink

I NEVER, EVER manually text while driving; ditto to email, etc.
I occasionally text while at a red light, but I'm configuring the phone to do that by voice.
