My opinion would change on a dime on my first receipt of a nasty-gram, however. They're fools if they allow this to remain a problem for users; their focus right now should be on making the system more popular. A substantial toll discount would be one way to go about it; they're saving money on toll collectors, so why not pass along the savings?
As for the congestion problem, it will ultimately shorten the wait time for the remaining cash lanes as the system gains popularity. Right now it's a pinch because so few people use EZpass, but that will change.
As for the "tracking" problem, it does concern me, but it's easily defeated in a pinch. The day I suspect that the government is seriously interested in my whereabouts is the day I loan my transponder to a trusted friend.
It might be nice, but I a mindful that I am passing by fellow citizens made miserable by our government. It makes it not so nice for me. If the government cannot employ enough people, and construct enough toll booths, so that those who have to pay don't have to wait, then they should find some other way to pay for the roads. The government routinely thinks that the citizen's time is worthless. I'm sure I spend a couple of hundred hours collecting information for the taxman (and then I have to pay someone $1000+ to put it all together because it's way too complicated for this Freeper with a couple of Math Degrees to do himself). It's involuntary servitude or, in the case of the tolls, false imprisonment.
