Clark has a daughter who has been driving for about three months now and she has had her first accident. The issues of safety and freedom are always on parents’ minds when their teen starts to drive. Clark has talked about the GPS systems and black boxes that parents can install in cars to track what their kids are up to. Nextel also has phones that allow employers to track the movements of workers or parents to track the location of their kids. The phones can pinpoint locations within a few hundred yards. So, if you’ve had some problems with your teen, you might want to consider installing one of these devices for his or her safety. Just be sure to tell your child. It should not be a deceitful move, but it’s definitely okay to be a nosy parent.
