What's the point of a number plate if it's not to allow a stranger at a distance to identify the car? It seems that Anti-ALPR plates are indeed a bug, although plates may be a misfeature.

The point is to allow a human to identify the car, not a network of cameras connected to a computer database. The ideal would be a plate that could be read by humans but not cameras, but failing that, a plate that can't be read by either is preferable to one that can be read by both. That still serves a purpose in satisfying legacy regulatory requirements to have a number plate even if it's now vestigial and no longer serves any non-bureaucratic purpose. The case for number plates has really eroded over time. Originally they couldn't be used for tracking because the logistics for that didn't exist, so that cost wasn't there and now it is. At the same time, their original value was always rather modest. The strongest case is for serious crimes like a hit and run, but even in those cases you need someone to get the plate number which they commonly fail to do, and in the most serious cases it's even less likely because a victim who dies can't remember the plate. So we're talking about it helping in a minority of a minority cases to begin with. Meanwhile in modern times it's more likely that the perpetrator will be caught on video (especially when every bystander has a camera phone), and then you have their face in combination with the make, model and color of the vehicle, which is enough to have a non-trivial chance of getting caught and preserve the deterrent even without the number plate. So on the one hand they now have a huge privacy cost that wasn't there before, on the other hand the value was never that high to begin with and it's even lower today than it was originally. So maybe we should just get rid of them.
