People without manners nor safe driving habits don't need cellphones to be annoying or to drive dangerously. Cellphones are just a tool, nothing more. You people who are railing against them probably pass by hundreds of people each day (assuming you get out of the house) who aren't talking loudly in a public place on their cellphone because it's in their pocket or their purse. You no doubt see people in cars, too, who have their cellphones in their holder/purse/pocket and aren't talking on it as they do 65 in a school zone. Cellphones don't have personalities and don't cause specific behaviors within others. They're just phones that don't have to be plugged in to work.
