We recently drove from Arizona to Arkansas. Due to the lack of superchargers between Oklahoma City and Little Rock, we had to dip down to Denton, TX and then across to the northeast of Dallas and back up to Little Rock. Along the way we met a toll road or two. I'm not really sure which ones as I was just blindly following the navigation directions as directed by the car. In addition, as far as I know, there are no toll roads in Arizona, leaving me fairly clueless as to how they work. Anyway, we ended up on some toll roads and never ran across any toll booths to pay. I saw the camera flashes go off a few times and am wondering if and when I'll be getting some bills in the mail. Any insights would be appreciated.
