CNet's Declan McCullagh breaks it down one time like they used to in 1984, when men were women, and the gradual erosion of anonymity was just an ironically distant rumbling. It seems Congress has endorsed a "standardized, electronically readable driver's license" initiative that would effectively end up being a Federal-level ID card. That's bad, I've been told, because such a technology will eventually have something to do with fiery demons taking our jobs as local grocery clerks or something like that. Honestly, as long as they wear flame-retardant aprons, I'm fine with it.
It seems that new US Passports will be RFID capable soon already, so I'd imagine a national standard driver's license would be something similar. That's not something they can track you from space with, but that's why we have satellites.
