If I would install such a device on my old car and it can tell me all of that, it can also tell anyone that has a way to connect to it the same information. I suspect it tracks you car viva satellite GPS. Why would I want to allow everyone to see how, where, and when I drive my old car? Its bad enough when my wife has to have her phone attached to herself 24 hours a day. I really don't want the government or anyone else tracking my every move.

The only advantage would be the slight possibility of it assisting in an arrest and the vehicle being returned after a theft, if the police were interested in such things these days. With few exceptions, In my opinion, the only way you get your car back these days is if no one else wants it. You seldom see a highly popular vehicle returned to the owner unless its really tore up.
