A few months ago, I told you about a new program available for pre-order that turns off your cell phones once the key is in your car's ignition.
Now, there's another similar service to keep you safe and free from distraction while driving. ZoomSafer is a free service that uses your phone's GPS system to monitor your driving speed and prevent you from placing or receiving calls or texts when traveling over 10 miles per hour. The application is programmable to allow exceptions, like calls from certain important numbers. And an added bonus for parents or employers who want to monitor the driving habits of kids or employees on the job: if the system is overridden and a call is placed or text message sent, the account administrator receives an automatically-generated email alerting them to the phone's usage.
Right now, the service is only available for BlackBerrys, but will work with select Windows and Android phones early next year. I think this kind of service is a good idea to prevent distractions, especially for people without the willpower to simply ignore the phone while behind the wheel.
