I don't see the connection between public surveillance and oppression that most other people here apparently see. With all other things equal, I'd rather not have the government know where I drive, simply because I enjoy having privacy in that domain for its own sake. However, I'm not afraid that the government will use this information to oppress me. (An oppressive government can oppress me whether or not I've actually done anything illegal, so the surveillance doesn't make much difference.) And in the absence of that concern about oppression, I value the potential to reduce crime more than I value my privacy while in public (something of a contradiction in terms).
