> My first reaction to privacy issues is, "well, why are you so worried about the government knowing where you're going?" But I suppose that information could be tampered with by bad people, or by big brother. The only invasion of privacy I've heard of is by parents, who check to see if their kids are *really* just sleeping over at a friend's house, or if they took the toll road down to the city to party.

I don't have a problem with the E-Z Pass in principle, I am worried by the idea that parents (private citizens) would have access to the data; that idea definately worries me. Surely there's good reason to keep that information out of the public domain.

I've included a link to a description of the road toll model that Britain is about to start trialing. I'd be interested to know what thoughts people have on constant satellite tracking of vehicals.
