This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Or put the letters and numerals in set spots, ex. ABC-123, next move onto 123-ABC once you’re done with the first bazillion combinations , AB3-12C, etc.
That way you can tell your 1 isn’t an I because it’s not in the right spot.
But once you've got cars on the road in both the first and second combination (or first and third, or whatever) then you can't easily tell if it's 111-III or III-111 or II1-11I.
in australia we had alpha and numeric divided and then a few years ago we switched to just alphanumeric everywhere… the font used is made to be machine readable - an I and a 1 look very different; it’s a non-issue
Yeah, using a smart font is a good solution.
In my state of my country the plates are colour coded. So like for most of the 90s it was green, now they're blue or something? I dunno, if you knew what to look for you could figure out what generational combination its from.
This is also a clever idea!
This is literally what CA does. 1AAA111, they've simply exhausted the pattern - 9ZZZ999 will go out sometime this year, according to the article.
Washington state had that for a while. They changed around a decade ago or so, maybe a little less. Now it's just a seven character plate, ABC1234.
UK includes the year in it, so it shouldn't ever really run out. Ok I guess eventually it will loop but I expect most will be available for reuse by then.
One issue could be if more cars are registered than the digits would make available for that year but you would probably just design it in a way there is significantly more space than you are ever realistically going to need.
We actually did loop in Denmark a decade or so ago. It was quite easy to guess the production year of the car by just looking at the first two letters. It was a bit trippy seeing new cars with "AA 11 111” all of a sudden when we ran out of ZZ's.
That would be pretty nice. Our plates are expensive over here (US) so we just put a new tiny year sticker on each time and keep the plates for a long time.
I think you might be mis-understanding slightly? In the UK the date is on the plate as part of the number e.g. AB25 6CD would be on a car registered in 2025. We don't have anything on cars like a registration (tax disk went long ago) number plates are big and plastic here for some reason, someone smart could probably explain why it's good or bad.
