Mounted to the windshield of my car is an I-Pass toll transponder, which is Illinois’s version of the E-ZPass toll transponder used to collect tolls throughout much of the eastern half of the country. I find it both fascinating and creepy that using a toll transponder creates an electronic record of your whereabouts:

The account was charged a total of $47.09.
