I hate transponder discrimination. To me, this is the antithesis of the entire EZPass idea. It’s a consortium. I have a PTC-issued EZPass. It drives me insane when I go to Long Island and have to pay the toll-by-mail rate.
This is why for a while, I had a Maryland-issued EZPass AND a New Jersey-issued EZPass: I was going back and forth between Philly and Maryland, and also using the bridges between Philly and South Jersey a bunch, so I wanted both the Hatem Bridge unlimited crossing plan AND the DRPA frequent user discount (which I've to this day never hit like I anticipated I might).
The other stupidity is the monthly fees. For YEARS living in Maryland, I had a Massachusetts-issued EZPass tag, because in the early 2000s I lived in the Boston area (my tag still said "Fast Lane" until its battery died). Mass didn't charge a monthly fee; Maryland did, and at the time I didn't use MD toll facilities enough to justify the in-state discount. As soon as Gov. Hogan dropped the monthly fee, I cancelled my Mass EZPass and got a Maryland one. Since MD charges a monthly fee for out-of-state addresses, I closed that account the instant I moved to PA.
Now I just have my NJ EZPass tag, and the $1 monthly fee, though chump change, is infuriating, and less than the PTC's $3 monthly fee -- that's the only reason I have the NJ EZPass as opposed to a PTC one; because the monthly fee is cheaper. Why some agencies charge monthly fees and some don't, and some are more than others, is also a mystery to me.
It pisses me off when I drive up to Connecticut to see family at the holidays, and have to pay the out-of-state toll rates at the Tappan Zee Bridge, GWB, et cetera. Software makes it just as easy to collect from an out-of-state EZPass issuer than an in-state one. New York State itself has several EZPass issuing agencies -- the NY Thruway authority, The PANYNJ, and MTA Bridges and Tunnels, to name three, and there may be more, so the in-state versus out-of-state rates make even LESS sense.
