See the work of Stephan Brands, and others, on capabability based credentials.
You don't need anything but the proof of a permission to drive, and
linkability of that proof-token to driving offenses in the database. Nobody
needs to see the identity credentials in the database unless you have to go
to trial.
Poof. No ID card. You can do this for all kinds of stuff, proof of age,
right to carry a concealed weapon on an aircraft, :-), or anything else.
Cheers,
