I'm filling out the information for insurance with USAA and I clicked to modify the safety equipement list just to see what the options where... the first question was "Does your vehicle have a vehicle tracking system?". They have demo'ed vehicle tracking on the iphone app, so I can answer YES?
Pretty sure they're asking about a system that the police can use to track a stolen car. I get a break because I have OnStar and police can not only track the car, they can slow it down and stop it once they catch up with it. There are after-market systems available that can track and report a stolen car's location.
