If a TLA is interested in you then you don't need to worry about a data log in your car.

The kind of organized crime that those people should be focused on are also resistant to this kind of tracking. The cartels and gangs just use burner cars that they dump, possibly with the keys and title still in it. Good luck doing much with the log but you've got the log and even the entire car to try and gather all the evidence you want. This tracking is mainly for hemming up small fry and productive citizens.
