Those must be new because all the ontario and quebeck fuckers who crossed the border to golf in Boca and West palm near the other white wing trumpista terrorists still have the old plates. Good luck to you come the spring when the canadia infected cross back over the border with floriduh rona straight from Trump and mar-a-lago. I would have thought the canuck snowbirds would have stayed away this year, but it seems they are as bad as americans.
OK, I've looked at a half dozen photos and videos of those plates becoming unreadable, and I still can't figure out exactly what's causing it.
I read up a little on it and it says that electronic plate readers have no problem reading these new plates, but they seem to not have been tested with the human eyes. Sounds like a technology update made by engineers trying to sell a new product. Engineers have tunnel vision lots of time and only take into account what they are wanting to sell, which appears to be plates to be read by HD plate readers and not human eyes. The different colors may be much more highly contrasted with a laser of a certain wavelength hitting them. Some commuhnities around here have bar code scanners for their automated gate entry systems. One of the ones I have on my car is black with a gold/black reflective bars. You have to look at it just right in the sun to see it with the naked eye, but when the red laser hits it then it works pretty well.
My guess would be the highway lighting is heavy on the blue spectrum causing colour vibration between the light blue and white of the plate.
