> 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.

...which is less "invasion of privacy" as "responsible parenting."

> A big issue in Illinois, which has a separate I-PASS, is that the toll rates are doubled for those who don't have the pass.

This feels like something you've got backwards. Tolls aren't doubled if you don't have the I-Pass -- they're cut in half if you do. Why? Because the costs of running the toll booths are lower, because you don't have to pay somebody to work at the booth, and so the state (or whatever entity collects the tolls) can afford to keep toll rates lower.

That is -- unless when Illinois instituted the I-Pass, they set the price at what then was the normal toll rate, then simultaneously doubled the rate for those without the pass. Then I'd see your point, certainly. It would be the state's prerogative to raise the tolls *and* to offer a discount for the I-Pass due to the lower costs -- it's just unfortunate and a little sleazy if they did both at the same time.
