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?

I wonder what the practical reason is for not just allowing full alphanumeric number plates. Each digit would then have 32 possibilities (I, O, Z, and S should be avoided to prevent confusion with 1, 0, 2, and 5). This gives 34.36 billion possible number plates which seems sufficient for at least the next couple years.
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.
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.
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.
