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?
Just post some stuff and don't spam.

I think you're grossly exaggerating the difficult of memorising alphanumeric number plates:

Especially if the system is designed so that you only need to remember the first/last four or five digits. Compare to these (found at random on the Internet) number plates under a mix of the two current schemes:

You can get away with just remembering the first four digits and the car's make, model, and colour. As long as fewer than 1 million (32^4) cars of the same model and colour are registered, this system guarantees that a car is uniquely identified by its colour, model, and first four of its number plate (i.e. "I was hit by a red Tesla Model X whose plate starts with
EL0N")If you don’t have time to get a photo you probably don’t have time to get the make. I’ve seen plenty of hit and run news reports where the witness just says “dark colored SUV”.
License plates need to be easy for humans to read and remember.
Random number plates are still likely to reduce the number of possibilities to just a few, likely visually distinct, cars.
