I respectfully suggest that at THIS time of the year - the vast majority of those using the tunnel in their private cars - wont be using it for commuting.
…The regular commuting users would know better than to even try.
The problems I have mentioned stem down to “There needs to be a couple of booths that are still manned” that take cash payments - even if it’s to be at the more expensive toll rate.
Remember when London Underground stations used to have all those ticket machines differentiated by “an amount”. Yet, there would always be a big queue of people who’ve either “got no change” or “dunno what the right ticket to buy is”
“Irregular users” proof the system ain’t - essentially.
The Oyster system really HAS simplified it, but an out-of-towner like myself who might only use the Tube a handful of times per year - is still not going to bother getting an oyster card… Luckily for me, I can buy a capitalcard on the day, and use that instead. Perhaps some “pre-paid” card in the “fire and forget” format is used. You Buy it on January 1st, say, stick it in your windscreen, and when you go through the tunnel - the card is cancelled by the use. A “crossing token” if you like. If you attempt to use the crossing without a valid form recognised by the system - a gantry sign at the crossing exit says something like “Registration 55IM NOB - Payment NOT met” to remind you that you’ve used a spent card, or are just a “traveller” who’s used to not paying for anything, but the system has reminded you that they “have your number”…
All the time there are pre-paid cards for mobile phone use (after all this time!) - what’s wrong with a “fire and forget” dart tag we can buy in WH SMiths or something? I don’t wanna put £10 on some account for something I’m only going to use in say, the boxing day sales at Lakeside…

Muckles:
It’s the “Newer regs” that I find stressful about London now. I had no bother in the 90’s, when you could go pretty much where you wanted, only looking out for “Low bridge” signs.
If it were only the registered keeper who got fined - then how come so many employed drivers GET fined then? - Because the “registered keeper” no doubt passed on the information “who was driving” instead of saying “Our motor - our fine. Here’s a cheque” at your transport office.
Why are they using a EU debt collection agency? - It’s so you can’t turn up at their offices and moan… Everything is geared to make money a one way street for this outfit, a concept I’ve never agreed with via ANY firm starting up some kind of “new system” to extract money out of people that shouldn’t be paying it in the first place.
Being foreign scooters, I have no idea if they are “over 49cc” like the scooters I am more familiar with are. I of course make the assumption that “Motorway rules NO L drivers, Mopeds, Motorcycles under 50cc” means just what it says…
Bills with itemization? - I was not aware that was the way things are going. Not if I’m even being argued out of “wanting to be able to see a pic of myself going through the tunnel” on a website I’ve been obliged to register with…
I’ve been online since 1985 - back when the best modems were the illegal ones. Accoustic Couplers were always rubbish, so I never bothered with them. I used to have an account on Prestel, later Micronet800 and it was from this time that I used the screen name “Winseer” as well. When the main worldwideweb started up, I signed up for accounts early enough that my email address doesn’t have any numbers in it either. I’m not “anti-technology” by any means, so I can’t really call myself a “luddite”. I just object to being forced to hand over account credits and personal details to firms who’s offices I’m never likely to visit. OK, so I have serious trust issues. If anyone had any real idea just how anonymous the internet was - they might understand my paranoia a bit better.
The notion that “crimes can be prevented” is total rubbish.
The internet is the greatest invention to the common crook since the invention of the dagger and the skeleton key. 
Paedos don’t get caught because someone can “monitor their messages between themselves” on-line. THey get caught when someone among them foolishly puts their computer in for repair, and the repairbod reports them from what they’ve found on the offending machine.
Bank robbery can be done with a simple “assurance” that the money sent across the world - was for actual delivery of goods and services that’ll be honoured. Who says it has to be honoured? Who’s gonna make that Nigerian or Moldovan you’ve just paid online send you ANYTHING at all?
The internet has rendered entire countries unworthy to be traded with these days.
Meanwhile, the few countries you thought you COULD trust - flog your data to anyone prepared to buy or hack it out of their computer banks. It comes as no surprise then, that any requests by a “young” firm for yet more rounds of personal details - will get met with the utmost suspicion by “old hand” cynical characters like me.
