This stemmed from a discussion in another thread. Do you? IF I have a need to make or take a call while driving, I use a bluetooth headset. It's not often I need to. Weekdays, I ALWAYS have my headset with me and turned on. It sits in a tray in the center console of my car, in front of the cup holders and within easy reach. Using this leaves both hands available for evasive moves and is no different than having a conversation with someone else in the vehicle, if not even safer because I wouldn't be tempted to turn to look at them. I can make a call without even looking at the phone (Moto X with touchless control) but will generally reserve interaction with the phone for when I'm stopped at a light. I actually find that I unintentionally slow down and scan my surroundings MORE if I happen to be on a call, though I generally know what vehicles are around me and where they are, even getting concerned when a vehicle approaching from behind slows down while in my blind spot causing me to lose sight of it.
