I could see that.
I guess if you were a municipality you might respond by increasing the frequency and coverage of ANPR and imtegrate alike systems, like you suggest garage records and location tracking, to compensate. TPMS has been used in traffic flow management, and a lot of places have transponders for tolling or private access.
Increasing surveillance might be controversial but maybe less so in .au?
License plates do seem anachronistic, ANPR notwithstanding.
Depending on the sophistication of the operation it opens up some interesting angles - if you can pay a gig worker to wait in line or chauffeur you, seems like it wouldn't be much more to pay someone to put on a plate and drive around safely. A /get out of tickets/ service.
