Well I've never understood the idea behind professional plates, but for certain groups, it allows them certain privileges not afforded to the common man.
In the case of physicians with physician plates, for example, if there's a medical emergency for which a physician would be useful, he can leave his car practically anywhere. I know it sounds trivial, and probably almost never happens, but it's there.
What I don't understand is why PTs, DCs, ODs, PAs, or any of the whole host of other healthcare professionals, need their own professional plates. That, especially in the case of ODs and DCs, is what I call arrogant.
