Four years ago, I drove through Oklahoma on the way to Arizona, and the damn toll booths were about the most frustrating thing I've ever gone through. Not that the buck you have to throw in bothers me, but that half of the damn automated things did not function properly. You'd throw the change in, and it didn't recognize that you threw it in. It was so irritating, that on the way back, I drove through Kansas instead just for that reason.
However, as bad as OK was, Illinois is by far worse. I go to the Chicago Auto Show every year. Between 2011 to 2012, apparently they either doubled or tripled each toll in just that one year. Last year, I did the math, and found that I actually spent more on tolls on the Illinois tollway than I burned in gas while on the tollway.
