re: #101 Belafon

If you don’t drive why would you have a drivers license?

Which why many states (sorry, no idea which ones they are) offer a “non-driver ID”, or something similar, for their dedicated-pedestrian residents who want/need an “official” identification document.
And IIRC (cites appreciated), some states that have enacted voter-ID requirements have been forced to provided (free) ID for otherwise non-driving voters. And yeah, that “poll tax” issue is a fairly settled one.
