I think this RMT Rover GPS tracking device would be a great tool to monitor a teen driver. I don't think it should be used to get out of a speeding ticket, but I do think it would keep my son in check when he is driving. I did a search and found the company that sells this device. The link is: http://www.rmtracking.com/teentracking.html... . I may just get one of these devices. If nothing else, it would probably help teens be more accountable for their actions.
