The Hands Free Headset

The blue tooth head piece for cell phones. Hands down one of the stupidest most frustrating inventions I have ever witnessed. I understand that some laws do not allow people to use their hands to hold their phones while driving but I am sure calls can wait. I mean nothing is more confusing then when I pull up to a red light and notice the man in the next car over making frightening gestures and screaming by himself in the car. I get really freaked out, and until I notice the little piece in his ear I wonder to myself how someone so obviously insane was ever allowed to operate a car. I mean, the whole reason you hold a cell phone up to your ear is that it is a signal to other people that you are, in fact, talking to someone else. We all look like idiots walking around screaming and talking to ourselves. Technology is a great thing and has helped us come so far as people, but this is one invention I really think has to go. On top of everything else, it hurts your ears, and is just kinda stupid.
