Some toll roads, like the Illinois Tollway, allow you to pay the tolls online afterwards for up to 7 days after your travel without paying a fine. Now that Waze is rolling out showing the cost of tolls, it should also let you track the tolls you pass on roads that have online payment options. Following your drive, you should be able to export a list of the tolls, and the time you passed them, as well as instructions for how to pay online. As it is now, other apps exist to do this, but it would be awesome if Waze did this automatically for you.
