GPS Trackers… Ethical for Children or Not?

Recently we added the Trackstick and the Trackstick Pro to our store.  These are really cool products, basically allowing you to track wherever you’ve been.  They log destinations using GPS, and then you go plug it into your computer, use it with Google Maps, and see a red line where you’ve been.  It even logs other info like how fast you were going.

The question is whether or not some applications for this product are ethical.  For instance, I’ve heard of people using this device to track their employees.  If it is a company car and the employees are supposed to be running strictly business related errands then I can see why an employer would need to monitor if the employee is staying on task and not wasting gas.  In fact, many companies and organizations use the Trackstick to figure out routes to increase response time (like paramedics) or to stretch out their gas budget.

I’ve had a friend however whose parents put a GPS tracker in her car without her knowing about it.  And I know this girl, she doesn’t have a history of getting in any real trouble.   She just has parents that are super paranoid about everything.  I’m of the opinion that this should only be done when you are pretty sure your teen is a reckless driver, gets drunk, or both.  What do you think?
