Yes it will bring a little safety. However, Ben Franklin once said: "Those who would give up essential liberty for temporary safety deserve neither liberty nor safety.":
If I were a Gazelle, I would choose the freedom and danger of the savanna over the comfort and safety of a zoo.
You're right, there is no correlation between individuals, the license plates the government assigns them, and their proximity in travel. I don't know what I was thinking.
Baaaah. Baaaaah.
I failed to see where the RFID prevented you from going ANYWHERE. Your same arguement would apply to simply putting a unique number on a license plate, and then publically displaying it. The only difference (and the ONLY difference) is that instead of relying upon an optical device to monitor license plates, we are using RF technologies. So, somehow using RFID is a violation of your 'rights', but publically displaying your license plate isn't?
