I'm lost without my cell phone. I even hold it while driving. I heard they can even stop you for this. My girlfriend uses a bluetooth headset. I for one can't stand these things. Call me old fashioned, but I like holding the phone to my ear when speaking.

& if it does interfere with my driving, I tell the person to hold on while turning or parking. But yes, there are idiots, sorry, IQ handicapped people out there that cannot talk & drive at the same time.
