Even GB [1] with a significant amount of #ANPR cameras, centralised vehicle licensing department and common formats for registration marks does not seem to have or use this - not for lack of technology as companies like Cleartone in #Wales have been building systems which can do this for about 20 years.
ANPR data is extensively used for gathering evidence for serious #crimes, and is gathered at things like car meets, raves etc but I suspect constabularies end up drowning in data and not being able to process it that quickly (or else I'd be hearing of a lot more folk being pulled up for things like undeclared mods..)
Most ANPR schemes tend to be only on highways and big towns..
[1] Northern Ireland has its own traffic authority and registration mark format
