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.
The issue is probably that those I, O, Z, and Ss are already on plates since the system is different?

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 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.

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.

I’ve always thought it dumb that the nation’s most populous state only uses seven of the possible eight characters on a license plate. Most states only use seven, but a dash separating letters and numbers means there is actually room for eight characters and many states will allow you to use all eight for vanity plates.
