text: If cell phones are so great why anyone hasn't came up with a device to turn the cell phone off automatically when driving. Now that would be technology in the making! If telephone companies and car manufactures could come up with a smart car that would be something to drive. Just imagine riding down the road and you have to call your friend to let him know you just saw his girl riding wither mom in the car right next to him. All of a certain the cell phone goes completely dead when you try to text or make a phone call. There is no sound and no light on your cell phone. Technology would be great if that would happen while someone is driving and texting or talking on the cell phone, the phone goes completely dead.
