DriveAssist

DriveAssist automatically holds all your calls, e-mails, and text messages while you're driving. You do absolutely nothing: the product "senses" when your phone is in motion and disables it until you step out of the car. Understandably, DriveAssist is being marketed to parents of teen drivers who don't want their children texting or chatting while driving. It offers moms and dads considerable control: they can override the system to let their own calls go through and can get updated GPS information about the whereabouts of their children. (Computer voice: "Johnny is at the corner of Main and Elm Street.")

Unfortunately, DriveAssist won't be available until next summer. It will cost between $5 and $10 a month, though Nationwide Insurance will be offering discounts to families who use it.
