personally Omag might think it strange but most people (or at least many ) are dead against this..they believe it infringes their civil rights and are terrrified that "Big Brother" will be watching their every move................
.......never mind that it helps in ways similar to your example and many other ways. too......."we must keep our civil rights intact at all costs."
It amazes me that a citizenry which apparently accepts police photorecon in just about every aspect of their lives, which accepts lisence plate tracking and photo-radar speeding tickets, and survelance cameras on every corner, would choose ID cards as a pivotal civil rights issue.
I'm all for civil rights, and I'm all for allowing people to wander the streets without the need to cary ID with them. But I wouldn't draw the line at ID cards. Take away that stupid police survalence stuff too. The police should assume that the citizens around them are innocent until they prove themselves otherwise, and there's no reason to snap a picture of the plate of an innocent driver and search it against a database looking for things amiss.
Once facial recognition technology comes I'm sure the police will be using that to check every person as they walk through every public place to make sure everyone is doing the right thing. Orwellian nightmares start long before governments hand out ID cards.
