True, but we Americans shouldn't have to go around like that.
Whoever thought up this tyrannical idea of tracking Americans needs to move to Russia or China. It is simply unAmerican.
at least in the NY metro area, they use it to track traffic patterns by seeing how fast a transponder moves from point A to point B along a particular highway. they give this information back to automated traffic systems and radio traffic reports. I haven't heard of any stories of misuse yet. I think if they started issuing traffic tickets with them, people would be dropping EZPASS in droves.
