Not because of disingenuous "car has a right to privacy" logic but because any judge would conclude that by tracking a car you're tracking the owner of the car and the owner does have a right to privacy.
I think you'll find that it has far more to do with directly interfering with another person's property without permission. If you publish someone's coordinates by using publicly accessible traffic cameras or (cost considerations aside) flying your own news helicopter around, the arguments become a lot vaguer. It's not clear that there's a legal/constitutional right to privacy in the US, and indeed recent supreme court decisions about abortion seem to reject the notion; jurisprudence in the 1970s saw an implicit right to privacy in certain constitutional provisions, an idea which 'originalists' regard as BS.
