If you want to know if your daughter really just went to the movies on her date, then this USB gadget will give you the lowdown without you having to hide in the trunk. What looks like a USB thumb drive is actually equipped with a GPS receiver that records wherever it goes. Simply load it up with a couple of AAA batteries, slip it into the glove box of her Civic, and wait for it to return. Once you retrieve the stick, you can plug it into your computer and it'll sync up with Google Earth, Google Maps, MapQuest, or Virtual Earth so you can see exactly where she went. It even records how long it took to get from Point A to Point B, so you can not only lecture her on lying about where she's been, but also about how fast she was driving on the way there. The tracker costs $250; available now.
