Hate to pile on, cookee, but the government or anyone having that much information about its people is dangerous. The potential for abuse is enormous. Let's say a woman co-worker of mine needs a ride home because her car is being repaired. And somehow this image (data) of her in my car makes it back to my wife/girlfriend, however innocent.
The potential for abuse, such as blackmail by unscrupulous government workers or private industry contracted to run this system, is very real. Private businesses having surveillance cameras for security is one thing, but for government to set up a national system, is another.
Every bone in my body says full time surveillance of my movements once I leave my house is not in my best interest or anyone else. Besides, I just donít like being spied upon however altruistic.
