Unfortunately, each State has its own ways of "proving" a DL is valid. Years ago, I need to get a Texas charitable organization license, but had to take a course on what to look for to prove a valid TX license. I was told we should never tell anybody, but we had dozens of people in the class. Thus, I cannot tell, but there are deliberate typos and coded numbers.

While I do not like the idea of granting government(s) more power, a national ID (to be used for identification, including voting and TSA) makes some sense since we have been told voter fraud is / is not a major problem and obtaining a valid ID is easy / difficult - depending upon your political stance - thus solving both "problems". Since States (including DC and territories) already issue DLs and even non-DL ID cards, it would be just moving the power from the States to the Federal government. Maybe the card could even have check marks indicating it is also a drivers license, Medicare card, hand gun permit, etc. (it should be a chip-enbedded card).
