IIRC this is a fee they charge you in order to have access to the vehicle's EZ pass, not for making actual trips across EZ pass bridges or the like. So if you're going to rent a car for a week and need to cross a bridge on one day, you have to enable the charge for the entire trip, or somehow prepay the charge via some website for the bridge. This is basically impossible for a tourist to figure out, of course, so they just profit from the complexity with an all-or-nothing system.
