I think you will find that many traffic systems now record and identify license plates and possibly can perform facial recognition as does the UK in London, and at soccer matches, for example.  While the transponder is a nice touch, the toll plazas easily track your account if the battery is dead as do the red light cams we have up north.  I think if someone did something bad all those resources would be brought to bear on tracking people or persons but I believe it is all being recorded and stored today.

I don't understand your comment on using a pilot name during an ATC Call.  Do you have a reference?
