ExpressToll, why do I need this dumb transponder?

ExpressToll makes no sense to me. Why do I have to have a stupid plastic box stuck to my windshield in order to get a better rate?

I have the dumb box, but the majority of the time the license plate cameras capture the toll anyway.

So obviously, the transponder isn't actually required. They figured out I was there, and they figured out that it was my account and not a random driver. Why do I need the transponder?

In fact how many of you have ever changed the battery in your transponder? One of mine has a battery test button (not the other), but why would I ever click it? Why put it in the window? Why do I need the transponder?

I set up an account with these guys a long time ago. I think that makes me a 'better' customer than one who hasn't (they get my money ahead of time). But because I'm a better customer, I have to stick a brick on my window? I'm clearly not understanding the logic here. Why do I need this transponder?

I just leave them at home on my workbench now. It seems to make no difference, yet…..

I was on the toll way last week and they were broadcasting on the big signs a plea to make sure you attach your transponder to your windshield. I suspect people (like me) have stopped doing it because the basic logic of the situation says, why?

Am I missing something here? This whole situation is making no sense to me.

It costs the toll agency more to process a video transaction because some human effort is required. Video technology is not as accurate as the transponder, so there is the risk of lost tolls. Some toll agencies add convenience charges or penalties for people that do not properly mount the transponder in order to offset their extra costs. Some consider it a violation of the user agreement depending on what you signed. I don't know the rules for the specific system you use but the agency knows can easily figure out what you are doing. Good luck.

@PaulM thanks for the great comment. So, what happens when all transponders in the field eventually go dead because the battery fails?

Todd - do you know there's a license-place mounted version of the transponder? They seem to work great and they'll deliver it right to your door. I've been using them for years, and no obstruction of view.
