By the point it's stolen, it's probably already too little too late. Not only will it probably be going to some impound lot before I can get to it -- it'll probably be on track to be my insurance company's car at that point. Seeing it on a map might be fun for curiosity's sake at that point, I guess.
No, and that's mostly the point right? If they get in the car, get an alert they're being tracked, then dump the car, at least you find it faster.
