If I had a photograph of you, something to remind me

I honestly cannot understand why someone would spend the money on a bluetooth headset then not take full advantage of its features. Today on my drive home from work I was nearly run out of the lane on spring street by some idiot in a bright yellow cobalt. I look over and see the flashing ear piece in place, only to notice that the driver is looking down at his phone and presumably flipping through the address book. Isn't the point of a "wireless" headset just that? to put the phone in the passenger seat, press the button on the side, and utilize the voice recognition software in an effort to pay closer attention to the road? come on people.
