Now Think Now

Cell phones are definitely one of the most distracting technologies! If there was a TV in my parents' car I drive, that would probably be more distracting than my cell phone.

The most annoying technology in the car? Human beings. Man, they can be annoying

All kidding aside, I would say cell phones without headsets or speech recognition. If you have a headset and speech recognition, you can just speak who you want to call and the phone will call. Anything that requires you to work with buttons is a bad idea - since you generally have to look at those buttons. Yeah, some people can "do it from memory," but they're pretty tempted to look down at that phone, or put the phone in an awkward position that lessens their control of the car.

Oh, and IPHONES... OMG. That stupid screen that you HAVE to stare at just to get it to do anything. Yeah, the 3GS has voice recognition, but c'mon... hardly makes it safer. Grr.

I vote cell phones too.  Most of what you have listed are manufacturer installed products that come with the car.  I-Tunes tagging, I pod car apps and in-car fridges shouldn't be used while driving.....These are the distractions!!!  And, I think TV displays in vehicles are just wrong. 

I vote on CELL PHONES!!!!!
