It seems that in California, at least, there is a legal distinction between a 'revoked' license and being 'unlicensed'.
In Australia, AFAIK there's no distinction; if you commit an offence serious enough to have your license revoked, then you no longer have a license and are unlicensed; i.e. it's the license that gives you the right to drive, and if your license is revoked then you don't have a license any more.
It's the same deal for suspensions - in Australia, if your license is suspended, then you're by definition unlicensed for the period.
So there may be a semantic mismatch where I misunderstood you.
It would seem that in California, pretty much the only way you could get a 12500(a) is if you'd never held a license at all; in this case, it fits your assertion that Hispanics are the only _unlicensed_ drivers.
