We have FLOCK everywhere, so I would hope they did their research. However, if they're worse, I am going to get one come November.
I assume the background is flat and the white would be reflective? I wonder how that works with plate readers. I think I have an older plate that was like this, but dark blue background. I'll need to take a look at it.
UK has compulsory yellow on black (rear) and black on white (front). As most govn spped etc cameras work on the rear view, i seems they decided black on yellow was the best combo. Our rules are really strict though for lettering font, spacing, size, material, refelctivity etc.
Black plates with white lettering can be purchased at extra cost in Texas. Those plates show up day and night on my two cameras used for license plate capture.
